=== Aggregations changes
|
|
|
|
[float]
|
|
==== Deprecated `global_ordinals_hash` and `global_ordinals_low_cardinality` execution hints for terms aggregations have been removed
|
|
|
|
These `execution_hint` are removed and should be replaced by `global_ordinals`.
|
|
|
|
[float]
|
|
==== `search.max_buckets` in the cluster setting
|
|
|
|
The dynamic cluster setting named `search.max_buckets` now defaults
|
|
to 10,000 (instead of unlimited in the previous version).
|
|
Requests that try to return more than the limit will fail with an exception.
|
|
|
|
[float]
|
|
==== `missing` option of the `composite` aggregation has been removed
|
|
|
|
The `missing` option of the `composite` aggregation, deprecated in 6.x,
|
|
has been removed. `missing_bucket` should be used instead.
|
|
|
|
[float]
|
|
==== Replaced `params._agg` with `state` context variable in scripted metric aggregations
|
|
|
|
The object used to share aggregation state between the scripts in a Scripted Metric
|
|
Aggregation is now a variable called `state` available in the script context, rather than
|
|
being provided via the `params` object as `params._agg`.
|
|
|
|
[float]
|
|
==== Make metric aggregation script parameters `reduce_script` and `combine_script` mandatory
|
|
|
|
The metric aggregation has been changed to require these two script parameters to ensure users are
|
|
explicitly defining how their data is processed.
|
|
|
|
[float]
|
|
==== `percentiles` and `percentile_ranks` now return `null` instead of `NaN`
|
|
|
|
The `percentiles` and `percentile_ranks` aggregations used to return `NaN` in
|
|
the response if they were applied to an empty set of values. Because `NaN` is
|
|
not officially supported by JSON, it has been replaced with `null`.
