From 2.0 adding child types to existing types was forbidden because the`_parent` field stores the join between parent and child at index time.
This is to protect from the fact that types that weren't a parent before become a parent while previously indexed documents would not have a join field.
This would break the parent/child queries.
The restriction was a bit too strict in the sense that also if a type was a parent type the restriction would forbid adding child types that point to a parent type (so child points already point to it).
This change make sure that the restriction only applies if that type isn't a parent type already.

* Register `indices.query.bool.max_clause_count` setting
This commit registers `indices.query.bool.max_clause_count` as a node
level setting and removes support for its synonym setting
`index.query.bool.max_clause_count`.

FSync translog outside of the writers global lock
Today we aquire a write global lock that blocks all modification to the
translog file while we fsync / checkpoint the file. Yet, we don't necessarily
needt to block concurrent operations here. This can lead to a lot of blocked
threads if the machine has high concurrency (lot os CPUs) but uses slow disks
(spinning disks) which is absolutely unnecessary. We just need to protect from
fsyncing / checkpointing concurrently but we can fill buffers and write to the
underlying file in a concurrent fashion.
This change introduces an additional lock that we hold while fsyncing but moves
the checkpointing code outside of the writers global lock.
Currently rounding intervals obtained by nextRoundingValue() for hour, minute and
second units can include an extra hour when happening at DST transitions that add
an extra hour (eg CEST -> CET). This changes the rounding logic for time units
smaller or equal to an hour to fix this.
Closes#18326
This commit adds simple GC overhead logging. This logging captures
intervals where the JVM is spending a lot of time performing GC but it
is not necessarily the case that each GC is large. For a start, this
logging is simple and does not attempt to incorporate whether or not the
collections were efficient (that is, we are only capturing that a lot of
GC is happening, not that a lot of useless GC is happening).

We are currently only parsing the array-syntax for the rescore part
in SearchSourceBuilder ("rescore" : [ {...}, {...} ]) . We also need
to support "rescore" : {...}

- Moves recovery logic into IndexShard
- Simplifies logic to cancel peer recovery of shard where recovery source node changed
- Ensures routing entry is set on initialization of IndexShard
With this commit we clear all caches after testing the parent circuit breaker.
This is necessary as caches hold on to circuit breakers internally. Additionally,
due to usage of CircuitBreaker#addWithoutBreaking() in caches, it's even possible
to go above the limit. As a consequence, all subsequent requests fall victim to
the limit.
Hence, right after the parent circuit breaker tripped, we clear all caches to
reduce these circuit breakers to 0 again. We also exclude the clear caches
transport request from limit check in order to ensure it will succeed. As this is
typically a very small and low-volume request, it is deemed ok to exclude it.
Closes#18325
This commit adds a variety of real disk metrics for the block devices
that back Elasticsearch data paths. A collection of statistics are read
from /proc/diskstats and are used to report the raw metrics for
operations and read/write bytes.

This commit refactors the JvmGcMonitorService so that it can be
tested. In particular, hooks are added to verify that the
JvmMonitorService correctly observes slow GC events, and that the
JvmGcMonitorService logs the correct messages.

Instead of re-exposing index metadata and blocks in RoutingNodes (which is part of the cluster state before rerouting), expose it as part of the RoutingAllocation which is known to be only temporarily used during reroute.
Sorts an array of values in ascending or descending order. If all elements are numerics, they will be sorted numerically. If values are strings, or mixtures of strings/numbers, the elements will be sorted lexicographically.
The change also renames fields and methods in the Profilers class.
Note that I had to make ProfileResult a public class (it was package private before) because now classes that call it are in a different package.
This change does the following:
- Queries that are currently unsupported such as prefix queries on numeric
fields or term queries on geo fields now throw an error rather than returning
a query that does not match anything.
- Fuzzy queries on numeric, date and ip fields are now unsupported: they used
to create range queries, we now expect users to use range queries directly.
Fuzzy, regexp and prefix queries are now only supported on text/keyword
fields (including `_all`).
- The `_uid` and `_id` fields do not support prefix or range queries anymore as
it would prevent us to store them more efficiently in the future, eg. by
using a binary encoding.
Note that it is still possible to ignore these errors by using the `lenient`
option of the `match` or `query_string` queries.
With this commit we add a precondition check to BulkRequest so
we fail early if users pass `null` for the request object.

Today, a race condition exists when retiring executors. Namely, if an
executor is retired and then the thread pool is terminated, the retiring
of the executor and the termination of the thread pool can race to
remove the retired executor from the queue of retired executors. More
precisely, when the executor is initially retired, it is placed on a
queue of retired executors, and then removed when it is successfully
shutdown. When the pool is terminated, it will also drain the queue of
retired executors. This leads to a time-of-check-time-of-use race where
the draining can see a retired executor on the queue but that retired
executor can be removed upon successful shutdown of that executor. This
leads to the draining attempting to remove an element from the queue
when there is none. This commit addresses this race condition by instead
safely polling the queue.
