This change adds a `_source` only snapshot repository that allows to wrap
any existing repository as a _backend_ to snapshot only the `_source` part
including live docs markers. Snapshots taken with the `source` repository
won't include any indices, doc-values or points. The snapshot will be reduced in size and
functionality such that it requires full re-indexing after it's successfully restored.
The restore process will copy the `_source` data locally starts a special shard and engine
to allow `match_all` scrolls and searches. Any other query, or get call will fail with and unsupported operation exception. The restored index is also marked as read-only.
This feature aims mainly for disaster recovery use-cases where snapshot size is
a concern or where time to restore is less of an issue.
**NOTE**: The snapshot produced by this repository is still a valid lucene index. This change doesn't allow for any longer retention policies which is out of scope for this change.
This endpoint accepts an arbitrary file in the request body and
attempts to determine the structure. If successful it also
proposes mappings that could be used when indexing the file's
contents, and calculates simple statistics for each of the fields
that are useful in the data preparation step prior to configuring
machine learning jobs.
It is useful to keep track of which version of a policy is currently
being executed by a specific index. For management purposes, it would
also be useful to know at which time the latest version was inserted
so that an audit trail is left for reconciling changes happening in ILM.
Auto Following Patterns is a cross cluster replication feature that
keeps track whether in the leader cluster indices are being created with
names that match with a specific pattern and if so automatically let
the follower cluster follow these newly created indices.
This change adds an `AutoFollowCoordinator` component that is only active
on the elected master node. Periodically this component checks the
the cluster state of remote clusters if there new leader indices that
match with configured auto follow patterns that have been defined in
`AutoFollowMetadata` custom metadata.
This change also adds two new APIs to manage auto follow patterns. A put
auto follow pattern api:
```
PUT /_ccr/_autofollow/{{remote_cluster}}
{
"leader_index_pattern": ["logs-*", ...],
"follow_index_pattern": "{{leader_index}}-copy",
"max_concurrent_read_batches": 2
... // other optional parameters
}
```
and delete auto follow pattern api:
```
DELETE /_ccr/_autofollow/{{remote_cluster_alias}}
```
The auto follow patterns are directly tied to the remote cluster aliases
configured in the follow cluster.

This removes `PhaseAfterStep` in favor of a new `PhaseCompleteStep`. This step
in only a marker that the `LifecyclePolicyRunner` needs to halt until the time
indicated for entering the next phase.
This also fixes a bug where phase times were encapsulated into the policy
instead of dynamically adjusting to policy changes.

This extracts a super class out of the rollup indexer called the AsyncTwoPhaseIterator.
The implementor of it can define the query, transformation of the response,
indexing and the object to persist the position/state of the indexer.
The stats object used by the indexer to record progress is also now abstract, allowing
the implementation provide custom stats beyond what the indexer provides. It also
allows the implementation to decide how the stats are presented (leaves toXContent()
up to the implementation).
This should allow new projects to reuse the search-then-index persistent task that Rollup
uses, but without the restrictions/baggage of how Rollup has to work internally to
satisfy time-based rollups.

We don't allow the user to configure a rollup index against an
existing index, but the exceptions that we return are not clear about
that. They indicate issues with metadata, instead of stating
the real reason (not allowed to use a non-rollup index to store
rollup data).
This makes the exception better, and adds a bit more testing
Today we fetch the mapping from the leader and apply it as a mapping
update whenever the index metadata version on the leader changes. Yet,
the index metadata can change for many reasons other than a mapping
update (e.g., settings updates, adding an alias, or a replica being
promoted to a primary among many other reasons). This commit builds on
the addition of a mapping version to the index metadata to only fetch
mapping updates when the mapping version increases. This reduces the
number of these fetches and application of mappings on the follower to
the bare minimum.
This commit adds tracking and reporting for fetch exceptions. We track
fetch exceptions per fetch, keeping track of up to the maximum number of
concurrent fetches. With each failing fetch, we associate the from
sequence number with the exception that caused the fetch. We report
these in the CCR stats endpoint, and add some testing for this tracking.

If a search request doesn't contain aggs (or an empty agg object),
we should just retun an empty response. This is how the normal search
API works if you specify zero hits and empty aggs.
The existing behavior throws an exception because it tries to send
an empty msearch.
Closes#32256
These two tests compliment the existing unit tests which check Rollup's
ACL/security integration.
The first test creates to indices, puts a document in each one, and then
assigns a role to the test user that can only access one of the indices.
A rollup job is created with a pattern that would match both indices,
and we verify that only the allowed document was rolled up (e.g. verifying
that the unpermissioned index stays hidden).
The second test creates a single index with two documents tagged by
the keyword "public"/"private". An attribute-based role is created
that only allows viewing "public" documents. We then verify the rollup
job only rolled the "public" doc, and not the "private" one.

* Store phase steps for index in PolicyStepsRegistry
This changes the way that steps are retrieved from `PolicyStepsRegistry` to
store the steps on a per-index basis (in memory for now, though that will change
in subsequent PRs). These steps are rebuilt as the index changes phases.
This also fixes a bug where an action with the same phase and name was not being
considered changed (and thus updated) in the compiled steps list. These are now
correctly considered as "upsert" diffs.

This commit removes the put privilege API in favor of having a single API to
create and update privileges. If we see the need to have an API like this in
the future we can always add it back.

Fix race between replica reset and primary promotion (#32442)
This commit addresses a race that can happen in the basic CCR stats REST
tests. Namely, peek reads can fire before the REST test client fires the
stats request. This means that we have to weaken our assertions about
the expected stats response.
Previously, we were using a simple CRC32 for the IDs of rollup documents.
This is a very poor choice however, since 32bit IDs leads to collisions
between documents very quickly.
This commit moves Rollups over to a 128bit ID. The ID is a concatenation
of all the keys in the document (similar to the rolling CRC before),
hashed with 128bit Murmur3, then base64 encoded. Finally, the job
ID and a delimiter (`$`) are prepended to the ID.
This gurantees that there are 128bits per-job. 128bits should
essentially remove all chances of collisions, and the prepended
job ID means that _if_ there is a collision, it stays "within"
the job.
BWC notes:
We can only upgrade the ID scheme after we know there has been a good
checkpoint during indexing. We don't rely on a STARTED/STOPPED
status since we can't guarantee that resulted from a real checkpoint,
or other state. So we only upgrade the ID after we have reached
a checkpoint state during an active index run, and only after the
checkpoint has been confirmed.
Once a job has been upgraded and checkpointed, the version increments
and the new ID is used in the future. All new jobs use the
new ID from the start
