|
==== Camel case and underscore parameters deprecated in 6.x have been removed
|
|
A number of duplicate parameters deprecated in 6.x have been removed from
|
|
Bulk request, Multi Get request, Term Vectors request, and More Like This Query
|
|
requests.
|
|
|
|
The following camel case parameters have been removed:
|
|
|
|
* `opType`
|
|
* `versionType`, `_versionType`
|
|
|
|
The following parameters starting with underscore have been removed:
|
|
|
|
* `_parent`
|
|
* `_retry_on_conflict`
|
|
* `_routing`
|
|
* `_version`
|
|
* `_version_type`
|
|
|
|
Instead of these removed parameters, use their non camel case equivalents without
|
|
starting underscore, e.g. use `version_type` instead of `_version_type` or `versionType`.
|
|
|

|
==== Thread pool info
|
|
|
|
In previous versions of Elasticsearch, the thread pool info returned in the
|
|
<<cluster-nodes-info,nodes info API>> returned `min` and `max` values reflecting
|
|
the configured minimum and maximum number of threads that could be in each
|
|
thread pool. The trouble with this representation is that it does not align with
|
|
the configuration parameters used to configure thread pools. For
|
|
<<modules-threadpool,scaling thread pools>>, the minimum number of threads is
|
|
configured by a parameter called `core` and the maximum number of threads is
|
|
configured by a parameter called `max`. For <<modules-threadpool,fixed thread
|
|
pools>>, there is only one configuration parameter along these lines and that
|
|
parameter is called `size`, reflecting the fixed number of threads in the
|
|
pool. This discrepancy between the API and the configuration parameters has been
|
|
rectified. Now, the API will report `core` and `max` for scaling thread pools,
|
|
and `size` for fixed thread pools.
|
|
|
|
Similarly, in the cat thread pool API the existing `size` output has been
|
|
renamed to `pool_size` which reflects the number of threads currently in the
|
|
pool; the shortcut for this value has been changed from `s` to `psz`. The `min`
|
|
output has been renamed to `core` with a shortcut of `cr`, the shortcut for
|
|
`max` has been changed to `mx`, and the `size` output with a shortcut of `sz`
|
|
has been reused to report the configured number of threads in the pool. This
|
|
aligns the output of the API with the configuration values for thread
|
|
pools. Note that `core` and `max` will be populated for scaling thread pools,
|
|
and `size` will be populated for fixed thread pools.

|
|
==== The parameter `fields` deprecated in 6.x has been removed from Bulk request
|
|
and Update request. The Update API returns `400 - Bad request` if request contains
|
|
unknown parameters (instead of ignored in the previous version).
|
|
|
|

|
|
[[remove-suggest-metric]]
|
|
==== Remove support for `suggest` metric/index metric in indices stats and nodes stats APIs
|
|
|
|
Previously, `suggest` stats were folded into `search` stats. Support for the
|
|
`suggest` metric on the indices stats and nodes stats APIs remained for
|
|
backwards compatibility. Backwards support for the `suggest` metric was
|
|
deprecated in 6.3.0 and now removed in 7.0.0.
|
|
|
|
[[remove-field-caps-body]]
|
|
|
|
In the past, `fields` could be provided either as a parameter, or as part of the request
|
|
body. Specifying `fields` in the request body as opposed to a parameter was deprecated
|
|
in 6.4.0, and is now unsupported in 7.0.0.
|
|
|
|
[float]
|
|
==== `copy_settings` is deprecated on shrink and split APIs
|
|
|
|
Versions of Elasticsearch prior to 6.4.0 did not copy index settings on shrink
|
|
and split operations. Starting with Elasticsearch 7.0.0, the default behavior
|
|
will be for such settings to be copied on such operations. To enable users in
|
|
6.4.0 to transition in 6.4.0 to the default behavior in 7.0.0, the
|
|
`copy_settings` parameter was added on the REST layer. As this behavior will be
|
|
the only behavior in 8.0.0, this parameter is deprecated in 7.0.0 for removal in
|
|
8.0.0.
|
|
|
|
[float]
|
|
==== The deprecated stored script contexts have now been removed
|
|
When putting stored scripts, support for storing them with the deprecated `template` context or without a context is
|
|
now removed. Scripts must be stored using the `script` context as mentioned in the documentation.
|
|
|
|
[float]
|
|
==== Get Aliases API limitations when {security} is enabled removed
|
|
|
|
The behavior and response codes of the get aliases API no longer vary
|
|
depending on whether {security} is enabled. Previously a
|
|
404 - NOT FOUND (IndexNotFoundException) could be returned in case the
|
|
current user was not authorized for any alias. An empty response with
|
|
status 200 - OK is now returned instead at all times.
|
|
|
|
[float]
|
|
==== Put User API response no longer has `user` object
|
|
|
|
The Put User API response was changed in 6.5.0 to add the `created` field
|
|
outside of the user object where it previously had been. In 7.0.0 the user
|
|
object has been removed in favor of the top level `created` field.
|
|
|
|
[float]
|
|
==== Source filtering url parameters `_source_include` and `_source_exclude` have been removed
|
|
|
|
The deprecated in 6.x url parameters are now removed. Use `_source_includes` and `_source_excludes` instead.
|
|
|
|
[float]
|
|
==== Multi Search Request metadata validation
|
|
|
|
MultiSearchRequests issued through `_msearch` now validate all keys in the metadata section. Previously unknown keys were ignored
|
|
while now an exception is thrown.
|
|
|
|
[float]
|
|
==== Deprecated graph endpoints removed
|
|
|
|
The deprecated graph endpoints (those with `/_graph/_explore`) have been
|
|
removed.
|
|
|
|
|
|
[float]
|
|
==== Deprecated `_termvector` endpoint removed
|
|
|
|
The `_termvector` endpoint was deprecated in 2.0 and has now been removed.
|
|
The endpoint `_termvectors` (plural) should be used instead.
