Most of the circuit breaker settings are dynamically configurable.
However, `indices.breaker.total.use_real_memory` is not. With this
commit we add a clarifying note that this specific setting is static.
Closes#44974
In order to make it easier to interpret the output of the ILM Explain
API, this commit adds two request parameters to that API:
- `only_managed`, which causes the response to only contain indices
which have `index.lifecycle.name` set
- `only_errors`, which causes the response to contain only indices in an
ILM error state
"Error state" is defined as either being in the `ERROR` step or having
`index.lifecycle.name` set to a policy that does not exist.
This PR addresses the feedback in https://github.com/elastic/ml-team/issues/175#issuecomment-512215731.
* Adds an example to `analyzed_fields`
* Includes `source` and `dest` objects inline in the resource page
* Lists `model_memory_limit` in the PUT API page
* Amends the `analysis` section in the resource page
* Removes Properties headings in subsections
With this change, we will return primary_term and seq_no of the current
document if an update is detected as a noop. We already return the
version; hence we should also return seq_no and primary_term.
Relates #42497
Adds an API to clone an index. This is similar to the index split and shrink APIs, just with the
difference that the number of primary shards is kept the same. In case where the filesystem
provides hard-linking capabilities, this is a very cheap operation.
Indexing cloning can be done by running `POST my_source_index/_clone/my_target_index` and it
supports the same options as the split and shrink APIs.
Closes#44128
* Switch from using docvalue_fields to extracting values from _source
where applicable. Doing this means parsing the _source and handling the
numbers parsing just like Elasticsearch is doing it when it's indexing
a document.
* This also introduces a minor limitation: aliases type of fields that
are NOT part of a tree of sub-fields will not be able to be retrieved
anymore. field_caps API doesn't shed any light into a field being an
alias or not and at _source parsing time there is no way to know if a
root field is an alias or not. Fields of the type "a.b.c.alias" can be
extracted from docvalue_fields, only if the field they point to can be
extracted from docvalue_fields. Also, not all fields in a hierarchy of
fields can be evaluated to being an alias.

We already have a note that the order of actions is up to ILM for each
phase, this commit puts the actions in the same order as they will be
executed.
Resolves#41729
This change adjusts the data frame transforms stats
endpoint to return a structure that is easier to
understand.
This is a breaking change for clients of the data frame
transforms stats endpoint, but the feature is in beta so
stability is not guaranteed.
Backport of #44350
Some small clarifications about force-merging and global ordinals, particularly
that global ordinals are cheap on a single-segment index and how this relates
to frozen indices.
Fixes#41687
In data frame transforms the same scheduler controls both
retries in the event of search failures and gaps between
checks for changes when the transform is running continuously.
Co-Authored-By: Lisa Cawley <lcawley@elastic.co>
This adds a new dynamic cluster setting `xpack.data_frame.num_transform_failure_retries`.
This setting indicates how many times non-critical failures should be retried before a data frame transform is marked as failed and should stop executing. At the time of this commit; Min: 0, Max: 100, Default: 10
Several files in the REST APIs nav section are included using
:leveloffset: tags. This increments headings (h2 -> h3, h3 -> h4, etc.)
in those files and removes the :leveloffset: tags.
Other supporting changes:
* Alphabetizes top-level REST API nav items.
* Change 'indices APIs' heading to 'index APIs.'
* Changes 'Snapshot lifecycle management' heading to sentence case.
elastic/elasticsearch#41281 added custom metadata parameter to
snapshots. During review, the parameter name was changed from '_meta' to
'metadata,' but the documentation wasn't updated. This corrects the
documentation to use the 'metadata' name.
* Expose index age in ILM explain output
This adds the index's age to the ILM explain output, for example:
```
{
"indices" : {
"ilm-000001" : {
"index" : "ilm-000001",
"managed" : true,
"policy" : "full-lifecycle",
"lifecycle_date" : "2019-07-16T19:48:22.294Z",
"lifecycle_date_millis" : 1563306502294,
"age" : "1.34m",
"phase" : "hot",
"phase_time" : "2019-07-16T19:48:22.487Z",
... etc ...
}
}
}
```
This age can be used to tell when ILM will transition the index to the
next phase, based on that phase's `min_age`.
Resolves#38988
* Expose age in getters and in HLRC
