Fix the timestamp field of a data stream to @timestamp (#59210)
Backport of #59076 to 7.x branch.

The commit makes the following changes:
* The timestamp field of a data stream definition in a composable
  index template can only be set to '@timestamp'.
* Removed custom data stream timestamp field validation and reuse the validation from `TimestampFieldMapper` and
  instead only check that the _timestamp field mapping has been defined on a backing index of a data stream.
* Moved code that injects _timestamp meta field mapping from `MetadataCreateIndexService#applyCreateIndexRequestWithV2Template58956(...)` method
  to `MetadataIndexTemplateService#collectMappings(...)` method.
* Fixed a bug (#58956) that cases timestamp field validation to be performed
  for each template and instead of the final mappings that is created.
* only apply _timestamp meta field if index is created as part of a data stream or data stream rollover,
this fixes a docs test, where a regular index creation matches (logs-*) with a template with a data stream definition.

Improve cardinality measure used to build aggs (#56533) (#59107)
This makes a `parentCardinality` available to every `Aggregator`'s ctor
so it can make intelligent choices about how it collects bucket values.
This replaces `collectsFromSingleBucket` and is similar to it but:
1. It supports `NONE`, `ONE`, and `MANY` values and is generally
   extensible if we decide we can use more precise counts.
2. It is more accurate. `collectsFromSingleBucket` assumed that all
   sub-aggregations live under multi-bucket aggregations. This is
   normally true but `parentCardinality` is properly carried forward
   for single bucket aggregations like `filter` and for multi-bucket
   aggregations configured in single-bucket for like `range` with a
   single range.

While I was touching every aggregation I renamed `doCreateInternal` to
`createMapped` because that seemed like a much better name and it was
right there, next to the change I was already making.

Add Check for Metadata Existence in BlobStoreRepository (#59141) (#59216)
In order to ensure that we do not write a broken piece of `RepositoryData`
because the phyiscal repository generation was moved ahead more than one step
by erroneous concurrent writing to a repository we must check whether or not
the current assumed repository generation exists in the repository physically.
Without this check we run the risk of writing on top of stale cached repository data.

Fix assertion in testCollectNodes test (#58948)
Currently we assert that the reason we fail collecting nodes in this
test is due to the fact that no seeds are available or no connections
could be established to cluster_2. However, the collection could fail if
we cannot establish connections to cluster_1. This commit adds that as
an acceptible assertion.

Sending operations concurrently in peer recovery (#58018)
Today, we send operations in phase2 of peer recoveries batch by batch
sequentially. Normally that's okay as we should have a fairly small of
operations in phase 2 due to the file-based threshold. However, if
phase1 takes a lot of time and we are actively indexing, then phase2 can
have a lot of operations to replay.

With this change, we will send multiple batches concurrently (defaults
to 1) to reduce the recovery time.

[7.x] Validate Data Streams reference a template on composable template update (#59106) (#59193)
This commit adds validation that when a composable index template is updated, that the number
of unreferenced data streams does not increase. While it is still possible to have data streams
without a backing template (through snapshot restoration), this reduces the chance of getting
in to that scenario.

Fix race in RecoveryRequestTrackerTests (#59187)
Currently in the recovery request tracker tests we place the futures
into the future map on the GENERIC thread. It is possible that the test
has already advanced past the point where we block on these futures
before they are placed in the map. This introduces other potential
failures as we expect all futures have been completed. This commit fixes
the test by places the futures in the map prior to dispatching.

Nik Everett d536854879 Fix test bug in auto_date_histo
The test would try to prepare a `Rounding` even when there aren't any

the rounding. It turns out that we don't need the rounding in that case
so we just use `null` then.

[7.9] GET data stream API returns additional information (#59128) (#59177)
* GET data stream API returns additional information (#59128)

This adds the data stream's index template, the configured ILM policy
(if any) and the health status of the data stream to the GET _data_stream
response.

Restoring a data stream from a snapshot could install a data stream that
doesn't match any composable templates. This also makes the `template`
field in the `GET _data_stream` response optional.

Nhat Nguyen de6ac6aea6 Fix recovery stage transition with sync_id (#57754)
If the recovery source is on an old node (before 7.2), then the recovery
target won't have the safe commit after phase1 because the recovery
source does not send the global checkpoint in the clean_files step. And
if the recovery fails and retries, then the recovery stage won't
transition properly. If a sync_id is used in peer recovery, then the
clean_files step won't be executed to move the stage to TRANSLOG.

Would fail with a 500 error and a message like:

      {
        "type": "illegal_state_exception",
        "reason":"async actions are left after rewrite"
      }
    ]
  }
}
```

This fixes that by moving the query rewrite phase from a synchronous
call on the data nodes into the standard aggregation rewrite phase which
can properly handle the asynchronous actions.

Remove nodes with read-only filesystems (#52680) (#59138)
Today we do not allow a node to start if its filesystem is readonly, but
it is possible for a filesystem to become readonly while the node is
running. We don't currently have any infrastructure in place to make
sure that Elasticsearch behaves well if this happens. A node that cannot
write to disk may be poisonous to the rest of the cluster.

With this commit we periodically verify that nodes' filesystems are
writable. If a node fails these writability checks then it is removed
from the cluster and prevented from re-joining until the checks start
passing again.

Add data stream timestamp validation via metadata field mapper (#59002)
Backport of #58582 to 7.x branch.

This commit adds a new metadata field mapper that validates,
that a document has exactly a single timestamp value in the data stream timestamp field and
that the timestamp field mapping only has `type`, `meta` or `format` attributes configured.
Other attributes can affect the guarantee that an index with this meta field mapper has a
useable timestamp field.

The MetadataCreateIndexService inserts a data stream timestamp field mapper whenever
a new backing index of a data stream is created.

This commit adds an integration test that component templates used to form a composite template can

In #58643 an issue arose where mappings were causing problems because of the way we unwrap `_doc` in

`MapperService` to do the merging. #58643 was fixed in 7.9 and master with the #58521 change, since
mappings now are read and digested by the actual mapper service.

This test passes for 7.x and master, and I intend to open a separate PR including this test for
7.8.1 along with a bug fix for #58643. This test is to ensure we don't have any regression in the

Account for recovery throttling when restoring snapshot (#58658) (#58811)
Restoring from a snapshot (which is a particular form of recovery) does not currently take recovery throttling into account
(i.e. the `indices.recovery.max_bytes_per_sec` setting). While restores are subject to their own throttling (repository
setting `max_restore_bytes_per_sec`), this repository setting does not allow for values to be configured differently on a
per-node basis. As restores are very similar in nature to peer recoveries (streaming bytes to the node), it makes sense to
configure throttling in a single place.

The `max_restore_bytes_per_sec` setting is also changed to default to unlimited now, whereas previously it was set to
`40mb`, which is the current default of `indices.recovery.max_bytes_per_sec`). This means that no behavioral change
will be observed by clusters where the recovery and restore settings were not adapted.

Account for remaining recovery in disk allocator (#58800)
Today the disk-based shard allocator accounts for incoming shards by
subtracting the estimated size of the incoming shard from the free space on the
node. This is an overly conservative estimate if the incoming shard has almost
finished its recovery since in that case it is already consuming most of the
disk space it needs.

This change adds to the shard stats a measure of how much larger each store is
expected to grow, computed from the ongoing recovery, and uses this to account
for the disk usage of incoming shards more accurately.

Introduce new put mapping action for dynamic mapping updates. (#58746)
Backport of #58419

Mapping updates that originate from indexing a document with unmapped fields will use this new action
instead of the current put mapping action. This way on the security side, authorization logic
can easily determine whether a mapping update is automatically generated or a mapping update originates
from the put mapping api.

The new auto put mapping action is only used if all nodes are on the version that supports it.

Merge mappings for composable index templates (#58709)
This PR implements recursive mapping merging for composable index templates.

When creating an index, we perform the following:
* Add each component template mapping in order, merging each one in after the
last.
* Merge in the index template mappings (if present).
* Merge in the mappings on the index request itself (if present).

Some principles:
* All 'structural' changes are disallowed (but everything else is fine). An
object mapper can never be changed between `type: object` and `type: nested`. A
field mapper can never be changed to an object mapper, and vice versa.
* Generally, each section is merged recursively. This includes `object`
mappings, as well as root options like `dynamic_templates` and `meta`. Once we
reach 'leaf components' like field definitions, they always overwrite an
existing one instead of being merged.

Relates to #53101.

Add index block api (#58716)
Adds an API for putting an index block in place, which also ensures for write blocks that, once successfully returning to
the user, all shards of the index are properly accounting for the block, for example that all in-flight writes to an index have
been completed after adding the write block.

This API allows coordinating more complex workflows, where it is crucial that an index is no longer receiving writes after
the API completes, useful for example when marking an index as read-only during an upgrade in order to reindex its
documents.

Allows SparseFileTracker to progressively execute listeners during Gap processing (#58477) (#58584)
Today SparseFileTracker allows to wait for a range to become available
before executing a given listener. In the case of searchable snapshot,
we'd like to be able to wait for a large range to be filled (ie, downloaded
and written to disk) while being able to execute the listener as soon as
a smaller range is available.

This pull request is an extract from #58164 which introduces a
ProgressListenableActionFuture that is used internally by
 SparseFileTracker. The progressive listenable future allows to register
listeners attached to SparseFileTracker.Gap so that they are executed
once the Gap is completed (with success or failure) or as soon as the
Gap progress reaches a given progress value. This progress value is
defined when the tracker.waitForRange() method is called; this method
has been modified to accept a range and another listener's range to
operate on.

Fix Incorrect Snapshot Shar Status for DONE Shards in Running Snapshots (#58390) (#58593)
Minor bugs/inconsistencies:

If a shard hasn't changed at all we were reporting `0` for total size and total file count
while it was ongoing.

If a data node restarts/drops out during snapshot creation the fallback logic did not load the correct statistic from the repository but just created a status with `0` counts from the snapshot state in the CS. Added a fallback to reading from the repository in this case.

Introduce node.roles setting (#58512)
Today we have individual settings for configuring node roles such as
node.data and node.master. Additionally, roles are pluggable and we have
used this to introduce roles such as node.ml and node.voting_only. As
the number of roles is growing, managing these becomes harder for the
user. For example, to create a master-only node, today a user has to
configure:
 - node.data: false
 - node.ingest: false
 - node.remote_cluster_client: false
 - node.ml: false

at a minimum if they are relying on defaults, but also add:
 - node.master: true
 - node.transform: false
 - node.voting_only: false

If they want to be explicit. This is also challenging in cases where a
user wants to have configure a coordinating-only node which requires
disabling all roles, a list which we are adding to, requiring the user
to keep checking whether a node has acquired any of these roles.

This commit addresses this by adding a list setting node.roles for which
a user has explicit control over the list of roles that a node has. If
the setting is configured, the node has exactly the roles in the list,
and not any additional roles. This means to configure a master-only
node, the setting is merely 'node.roles: [master]', and to configure a
coordinating-only node, the setting is merely: 'node.roles: []'.

With this change we deprecate the existing 'node.*' settings such as
'node.data'.

Add Variable Width Histogram Aggregation (backport of #42035) (#58440)
Implements a new histogram aggregation called `variable_width_histogram` which
dynamically determines bucket intervals based on document groupings. These
groups are determined by running a one-pass clustering algorithm on each shard
and then reducing each shard's clusters using an agglomerative
clustering algorithm.

This PR addresses #9572.

The shard-level clustering is done in one pass to minimize memory overhead. The
algorithm was lightly inspired by
[this paper](https://ieeexplore.ieee.org/abstract/document/1198387). It fetches
a small number of documents to sample the data and determine initial clusters.
Subsequent documents are then placed into one of these clusters, or a new one
if they are an outlier. This algorithm is described in more details in the
aggregation's docs.

At reduce time, a
[hierarchical agglomerative clustering](https://en.wikipedia.org/wiki/Hierarchical_clustering)
algorithm inspired by [this paper](https://arxiv.org/abs/1802.00304)
continually merges the closest buckets from all shards (based on their
centroids) until the target number of buckets is reached.

The final values produced by this aggregation are approximate. Each bucket's
min value is used as its key in the histogram. Furthermore, buckets are merged
based on their centroids and not their bounds. So it is possible that adjacent
buckets will overlap after reduction. Because each bucket's key is its min,
this overlap is not shown in the final histogram. However, when such overlap
occurs, we set the key of the bucket with the larger centroid to the midpoint
between its minimum and the smaller bucket’s maximum:
`min[large] = (min[large] + max[small]) / 2`. This heuristic is expected to
increases the accuracy of the clustering.

Nodes are unable to share centroids during the shard-level clustering phase. In
the future, resolving https://github.com/elastic/elasticsearch/issues/50863
would let us solve this issue.

It doesn’t make sense for this aggregation to support the `min_doc_count`
parameter, since clusters are determined dynamically. The `order` parameter is
not supported here to keep this large PR from becoming too complex.

We use early termination when the number of hits to track is reached during collection

Users are perennially confused by the message they get when writing to
an index is blocked due to excessive disk usage:

    TOO_MANY_REQUESTS/12/index read-only / allow delete (api)

Of course this is technically accurate but it is hard to join the dots
from this message to "your disk was too full" without some searching of
forums and documentation. Additionally in #50166 we changed the status
code to today's `429` from the previous `403` which changed the message
from the one that's widely documented elsewhere:

    FORBIDDEN/12/index read-only / allow delete (api)

Since #42559 we've considered this block to be under the sole control of
the disk-based shard allocator, and we have seen no evidence to suggest
that anyone is applying this block manually. Therefore this commit
adjusts this block's message to indicate that it's caused by a lack of
disk space.

It was previously possible to include a similarity parameter on a number of field types
that would then ignore this information. To make it obvious that this has no effect, setting
this parameter on non-text field types now issues a deprecation warning.

Save Shard ID Serializations in Bulk Requests (#56209) (#58414)
Just like #56094 but for the request side.
Removes a lot of redundant `ShardId` instances from bulk shard requests as well as stops serializing index names when they're not needed because they're not different from what is in the shard id.

Even ignoring the index name serialization savings here, this change saves one `ShardId` instance per bulk shard request at least. This means it saves approximately:

* 8 bytes for the `ShardId` object (itself + one field)
   * + another 4 bytes for the `int` in the `ShardId`
* 16 bytes (two fields + the instance itself + the padding) for the `Index` object
   * + 30 bytes for the `Index` uuid string
   * + all the bytes in the index name string

=> 60+ bytes per bulk request item saved on heap and over the wire

curerently gets parsed to a BigInteger object, that the various term query
builders store untouched. This leads to serialization errors when these queries
are sent across the wire. Instead we can convert to a string representation
early on, since that is what we store e.g. when indexing big integers into
`keyword` fields anyway.

Closes #57917

Allow index filtering in field capabilities API (#57276) (#58299)
This change allows to use an `index_filter` in the
field capabilities API. Indices are filtered from
the response if the provided query rewrites to `match_none`
on every shard:

````
GET metrics-*
{
  "index_filter": {
    "bool": {
      "must": [
        "range": {
          "@timestamp": {
            "gt": "2019"
          }
        }
      }
  }
}
````

The filtering is done on a best-effort basis, it uses the can match phase
to rewrite queries to `match_none` instead of fully executing the request.
The first shard that can match the filter is used to create the field
capabilities response for the entire index.

Yannick Welsch ffeff4090e Add new flag to check whether alias exists on remove (#58100)
This allows doing true CAS operations on aliases, making sure that an alias is actually properly
moved from a given source index onto a given target index. This is useful to ensure that an
alias is actually moved from a given index to another one, and not just added to another index.

Retry failed replication due to transient errors (#56230)

Save memory when auto_date_histogram is not on top (backport of #57304) (#58190)
This builds an `auto_date_histogram` aggregator that natively aggregates
from many buckets and uses it when the `auto_date_histogram` used to use
`asMultiBucketAggregator` which should save a significant amount of
memory in those cases. In particular, this happens when
`auto_date_histogram` is a sub-aggregator of a multi-bucketing aggregator
like `terms` or `histogram` or `filters`. For the most part we preserve
the original implementation when `auto_date_histogram` only collects from
a single bucket.

It isn't possible to "just port the aggregator" without taking a pretty
significant performance hit because we used to rewrite all of the
buckets every time we switched to a coarser and coarser rounding
configuration. Without some major surgery to how to delay sub-aggs
we'd end up rewriting the delay list zillions of time if there are many
buckets.

The multi-bucket version of the aggregator has a "budget" of "wasted"
buckets and only rewrites all of the buckets when we exceed that budget.
Now that we don't rebucket every time we increase the rounding we can no
longer get an accurate count of the number of buckets! So instead the
aggregator uses an estimate of the number of buckets to trigger switching
to a coarser rounding. This estimate is likely to be *terrible* when
buckets are far apart compared to the rounding. So it also uses the
difference between the first and last bucket to trigger switching to a
coarser rounding. Which covers for the shortcomings of the bucket
estimation technique pretty well. It also causes the aggregator to emit
fewer buckets in cases where they'd be reduced together on the
coordinating node. This is wonderful! But probably fairly rare.

All of that does buy us some speed improvements when the aggregator is
a child of multi-bucket aggregator:
Without metrics or time zone: 25% faster
With metrics: 15% faster
With time zone: 22% faster

Fix Snapshot Abort Not Waiting for Data Nodes (#58214) (#58228)
This was a really subtle bug that we introduced a long time ago.
If a shard snapshot is in aborted state but hasn't started snapshotting on a node
we can only send the failed notification for it if the shard was actually supposed
to execute on the local node.
Without this fix, if shard snapshots were spread out across at least two data nodes
(so that each data node does not have all the primaries) the abort would actually
never wait on the data nodes. This isn't a big deal with uuid shard generations
but could lead to potential corruption on S3 when using numeric shard generations
(albeit very unlikely now that we have the 3 minute wait there).
Another negative side-effect of this bug was that master would receive a lot more
shard status update messages for aborted shards since each data node not assigned
a primary would send one message for that primary.

Fix DanglingIndicesIT Failures from MasterNotDiscoveredException (#58215) (#58221)
The dangling indices action is not a proper master node action so it does not
retry when executed while the cluster hasn't fully formed yet.
Since we use node restarts when setting up the dangling indices state we need
to manually ensure a fully formed cluster before moving on with the tests to avoid
failures.

MappedFieldType should not extend FieldType (#58160)
MappedFieldType is a combination of two concerns:

* an extension of lucene's FieldType, defining how a field should be indexed
* a set of query factory methods, defining how a field should be searched

We want to break these two concerns apart. This commit is a first step to doing this, breaking
the inheritance relationship between MappedFieldType and FieldType. MappedFieldType
instead has a series of boolean flags defining whether or not the field is searchable or
aggregatable, and FieldMapper has a separate FieldType passed to its constructor defining
how indexing should be done.

Fix ExtraFS Breaking SharedClusterSnapshotRestoreIT (#58026) (#58040)
If `ExtraFS` decides to put `extra0/0` into the indices folder
then the previous logic in this test would have interpreted the `0`
as shard `0` of index `extra0` and fail to list its contents (since it's a file
and not an actual shard directory).

=> simplified the logic to use actually referenced `IndexId` for iterating over indices
instead.
