Today if the connection to S3 times out or drops after starting to download an
object then the SDK does not attempt to recover or resume the download, causing
the restore of the whole shard to fail and retry. This commit allows
Elasticsearch to detect such a mid-stream failure and to resume the download
from where it failed.
* Write metadata during snapshot finalization after segment files to prevent outdated metadata in case of dynamic mapping updates as explained in #41581
* Keep the old behavior of writing the metadata beforehand in the case of mixed version clusters for BwC reasons
* Still overwrite the metadata in the end, so even a mixed version cluster is fixed by this change if a newer version master does the finalization
* Fixes#41581
Handle queries with implicit GROUP BY where the aggregation is not in
the projection/SELECT but inside the filter/HAVING such as:
SELECT 1 FROM x HAVING COUNT(*) > 0
The engine now properly identifies the case and handles it accordingly.
Fix#37051
(cherry picked from commit fa53ca05d8219c27079b50b4a5b7aeb220c7cde2)
Improve the defensive behavior of ResultSet when dealing with incorrect
API usage. In particular handle the case of dealing with no row
available (either because the cursor is before the first entry or after
the last).
Fix#46750
(cherry picked from commit 58fa38e4606625962e879265d35eacb0960c6cdb)
Without replicas we won't actually get any relocations
going when removing the node constraints in this test.
Adjusted the code to force relocations by forbidding
nodes that hold primaries instead.
Also, fixed the timeouts and asserted that we actually
get relocations.

* [DOCS] Adds outlier detection params to the data frame analytics resources.

The just released SQuirrel SQL 4.0.0 provides an Elasticsearch driver
definition out of the box; update the documentation to reflect that.

* [ILM] Add date setting to calculate index age
Add the `index.lifecycle.origination_date` to allow users to configure a
custom date that'll be used to calculate the index age for the phase
transmissions (as opposed to the default index creation date).
This could be useful for users to create an index with an "older"
origination date when indexing old data.
Relates to #42449.
* [ILM] Don't override creation date on policy init
The initial approach we took was to override the lifecycle creation date
if the `index.lifecycle.origination_date` setting was set. This had the
disadvantage of the user not being able to update the `origination_date`
anymore once set.
This commit changes the way we makes use of the
`index.lifecycle.origination_date` setting by checking its value when
we calculate the index age (ie. at "read time") and, in case it's not
set, default to the index creation date.
* Make origination date setting index scope dynamic
* Document orignation date setting in ilm settings

* Parallelize Repository Cleanup Actions
Deleting root blobs and unreferenced indices can safely happen in parallel,
no need to have both operations run sequentially when they preclude all other
repository operations.
When the stop API is called while the task is running there is
a chance the task gets marked completed twice. This may cause
undesired side effects, like indexing the progress document a second
time after the stop API has returned (the cause for #46705).
This commit adds a check that the task has not been completed before
proceeding to mark it so. In addition, when we update the task's state
we could get some warnings that the task was missing if the stop API
has been called in the meantime. We now check the errors are
`ResourceNotFoundException` and ignore them if so.
Closes#46705
Backports #46721
We added docs for proxy mode in #40281 but on reflection we should not be
documenting this setting since it does not play well with all proxies and we
can't recommend its use. This commit removes those docs and expands its Javadoc
instead.
We renew the CCR retention lease at a fixed interval, therefore it's
possible to have more than one in-flight renewal requests at the same
time. If requests arrive out of order, then the assertion is violated.
Closes#46416Closes#46013
This is fixing a bug where if an analytics job is started before any
anomaly detection job is opened, we create an index after the state
write alias.
Instead, we should create the state index and alias before starting
an analytics job and this commit makes sure this is the case.
Backport of #46602
Synced-flush consists of three steps: (1) force-flush on every active
copy; (2) check for ongoing indexing operations; (3) seal copies if
there's no change since step 1. If some indexing operations are
completed on the primary but not replicas, then Lucene commits from step
1 on replicas won't be the same as the primary's. And step 2 would pass
if it's executed when all pending operations are done. Once step 2
passes, we will incorrectly emit the "out of sync" warning message
although nothing wrong here.

There's nothing wrong in the logs from these failures. I think 30
seconds might not be enough to relocate shards with many documents as CI
is quite slow. This change increases the timeout to 60 seconds for these
relocation tests. It also dumps the hot threads in case of timed out.

The sample code is wrong. Field type is required for the sample field.
I guess the intention was to give the sample field the name ```fingerprint```, mapping it as ```text``` using the custom analyzer ```my_analyzer```
This change delays the creation of the SubSearchContext for nested and parent/child inner_hits
to the fetch sub phase in order to ensure that a SearchContext can built entirely from a
QueryShardContext. This commit also adds a validation step to the inner hits builder that ensures that we fail the request early if the inner hits path is invalid.

The changes in #32006 mean that the discovery process can no longer use
master-ineligible nodes as a stepping-stone between master-eligible nodes.
This was normally an indication of a strange and possibly-fragile configuration
and was not recommended, but this commit adds a note to the breaking changes
docs to note that this kind of configuration is more obviously broken in recent
versions.
This test verifies automatic cancellation of search requests on connection close.
It was previously not present in 7.x as the http client was subject do a bug which
made testing cancellation of requests impossible. Now that the bug is fixed upstream,
we can also backport this test
Add a section to both the low level and high level client documentation on asynchronous usage and `Cancellable` added for #44802
Co-Authored-By: Lee Hinman <dakrone@users.noreply.github.com>
This commits makes all the async methods in the high level client return the `Cancellable` object that the low level client now exposes.
Relates to #45379Closes#44802
The low-level REST client exposes a `performRequestAsync` method that
allows to send async requests, but today it does not expose the ability
to cancel such requests. That is something that the underlying apache
async http client supports, and it makes sense for us to expose.
This commit adds a return value to the `performRequestAsync` method,
which is backwards compatible. A `Cancellable` object gets returned,
which exposes a `cancel` public method. When calling `cancel`, the
on-going request associated with the returned `Cancellable` instance
will be cancelled by calling its `abort` method. This works throughout
multiple retries, though some special care was needed for the case where
`cancel` is called between different attempts (when one attempt has
failed and the consecutive one has not been sent yet).
Note that cancelling a request on the client side does not automatically
translate to cancelling the server side execution of it. That needs to be
specifically implemented, which is on the work for the search API (see #43332).
