The `composite` aggregation uses a TreeMap to keep track of the best buckets.
This ensures a log(n) time cost to insert new buckets but also to retrieve buckets
that are already present in the map. In order to speed up the retrieval of buckets
this change replaces the TreeMap with a priority queue and a HashMap. The insertion
cost is still log(n) but the retrieval of buckets through the HashMap is now done in constant
time. This optimization can bring significant improvement since each document needs
to check if its associated buckets are already present in the current best buckets.
The QueryStringQueryBuilder does not currently delegate to the field mapper's prefixQuery
method, so does not use indexed prefixes. This commit corrects this.
It also fixes a bug where a query a* would not match the word a if indexed prefixes were used with
a minchar setting of 2.
Negative timestamps are currently supported in joda time. These are
dates before epoch. However, it doesn't really make sense to have a
negative timestamp, since this is a modern format. Any dates before
epoch can be represented with normal date formats, like ISO8601.
Additionally, implementing negative epoch timestamp parsing in java time
has an edge case which would more than double the code required. This
commit deprecates use of negative epoch timestamps.
The default index_prefix settings will index prefixes of between 2 and 5 characters in length.
Currently, if a prefix search falls outside of this range at either end we fall back to a standard prefix
expansion, which is still very expensive for single character prefixes. However, we have an option
here to use a wildcard expansion rather than a prefix expansion, so that a query of a* gets remapped
to a? against the _index_prefix field - likely to be a very small set of terms, and certain to be much
smaller than a* against the whole index.
This commit adds this extra level of mapping for any prefix term whose length is one less than
the min_chars parameter of the index_prefixes field.
* Deprecate types in index API
- deprecate type-based constructors of IndexRequest
- update tests to use typeless IndexRequest constructors
- no yaml tests as they have been already added in #35790

This change adds a new untyped endpoint `{index}/_source/{id}` for both the
GET and the HEAD methods to get the source of a document or check for its
existance. It also adds deprecation warnings to RestGetSourceAction that emit
a warning when the old deprecated "type" parameter is still used. Also updating
documentation and tests where appropriate.

This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

This commit makes `document`, `update`, `explain`, `termvectors` and `mapping`
typeless APIs work on indices that have a type whose name is not `_doc`.
Unfortunately, this needs to be a bit of a hack since I didn't want calls with
random type names to see documents with the type name that the user had chosen
upon type creation.
The `explain` and `termvectors` do not support being called without a type for
now so the test is just using `_doc` as a type for now, we will need to fix
tests later but this shouldn't require further changes server-side since passing
`_doc` as a type name is what typeless APIs do internally anyway.

The support for rest_total_hits_as_int has already been merged to 6x
in #35848 so this change adds this new option to master. The plan was
to add this new option as part of #35848 but we've decided to wait a few
days before merging this breaking change so this commit just handles
the new option as a noop exactly like 6x for now. This will allow
users to migrate to this parameter before #35848 is merged.

The `wait_for_metadata_version` parameter will instruct the cluster state
api to only return a cluster state until the metadata's version is equal or
greater than the version specified in `wait_for_metadata_version`. If
the specified `wait_for_timeout` has expired then a timed out response
is returned. (a response with no cluster state and wait for timed out flag set to true)
In the case metadata's version is equal or higher than `wait_for_metadata_version`
then the api will immediately return.
This feature is useful to avoid external components from constantly
polling the cluster state to whether somethings have changed in the
cluster state's metadata.
* Deprecate types in count requests.
* Move RestCountAction to the 'search' package.
* Deprecate types in multi search requests.
* Add tests for types deprecation in the _search endpoint.
We've decided that the bulk, delete, get, index, update, and search APIs should not
contain this request parameter, and we will instead accept both typed and typeless calls.
Today if a wildcard, date-math expression or alias expands/resolves
to an index that is search-throttled we still search it. This is likely
not the desired behavior since it can unexpectedly slow down searches
significantly.
This change adds a new indices option that allows `search`, `count`
and `msearch` to ignore throttled indices by default. Users can
force expansion to throttled indices by using `ignore_throttled=true`
on the rest request to expand also to throttled indices.

This commit adds a new single value metric aggregation that calculates
the statistic called median absolute deviation, which is a measure of
variability that works on more types of data than standard deviation
Our calculation of MAD is approximated using t-digests. In the collect
phase, we collect each value visited into a t-digest. In the reduce
phase, we merge all value t-digests, then create a t-digest of
deviations using the first t-digest's median and centroids
Deprecates `_source_include` and `_source_exclude` url parameters
in favor of `_source_inclues` and `_source_excludes` because those
are consistent with the rest of Elasticsearch's APIs.

This change adds throttling to the update-by-query and delete-by-query cases
similar to throttling for reindex. This mostly means additional methods on the
client class itself, since the request hits the same RestHandler, just with
slightly different endpoints, and also the return values are similar.
Mappings with completion type and multi-fields, were not able to index array or
object format on completion fields. Only string format was supported.
This is fixed by providing multiField parser with externalValueContext with already parsed object
closes#15115
Although we allow to index BigInteger and BigDecimal into a keyword
field, source filtering on these fields would fail
as XContentBuilder was not able to deserialize BigInteger and BigDecimal
to json.
This modifies XContentBuilder to allow to handle BigInteger and
BigDecimal.
Closes#32395
This commit duplicates REST tests for the
- `indices.create`
- `indices.put_mapping`
- `indices.get_mapping`
- `index`
- `get`
- `delete`
- `update`
- `bulk`
APIs, so that we both test them when used without types (include_type_name=false)
and with types, mostly for mixed-version cluster tests.
Given a suite called `X_test_name.yml`, I first copied it to
`(X+1)_test_name_with_types.yml` and then changed `X_test_name.yml` to set
`include_type_name=false` on every API that supports it.

This commit fixes bwc rest tests for the doc_values format deprecation
in search. The message of the deprecation changed in 6.4.1 so the bwc test
should not check against 6.4.0.
* Improves doc values format deprecation message
This changes the deprecation message when doc values fields do not
supply a format form logging a deprecation warning for each offending
field individually to logging a single message which lists all
offending fields
Closes#33572
* Updates YAML test with new deprecation message
Also adds a test to ensure multiple deprecation warnings are collated
into one message
* Condenses collection of fields without format check
Moves the collection of fields that don't have a format to a separate
loop and moves the logging of the deprecation warning to be next to it
at the expesnse of looping through the field list twice
* fixes typo
* Fixes test
Now that types are unique per mapping we can retrieve the document mapper
without referencing the type. This fixes an NPE when stored fields are disabled.
For 6x we'll need a different fix since mappings can still have multiple types.
