=== Fixed index corruption on shrunk indices
|
|
|
|
Applying deletes or updates on an index after it had been shrunk would likely
|
|
corrupt the index. We advise users of Elasticsearch 6.x who opt in for soft
|
|
deletes on some of their indices and all users of Elasticsearch 7.x to upgrade
|
|
to 7.7 as soon as possible to no longer be subject to this corruption bug. In
|
|
case upgrading in the near future is not an option, we recommend to completely
|
|
stop using `_shrink` on read-write indices and to do a force-merge right after
|
|
shrinking on read-only indices, which significantly reduces the likeliness of
|
|
being affected by this bug in case deletes or updates get applied by mistake.
|
|
This bug is fixed as of {es} 7.7.0. Low-level details can be found on the
|
|
https://issues.apache.org/jira/browse/LUCENE-9300[corresponding issue].

=== {transforms-cap}
|
|
|
|
We introduced {transforms} in 7.2.0 as a beta feature. It is now mature enough
|
|
to declare the feature GA (general availability). {transforms-cap} enable you to
|
|
pivot and summarize your data and store it in a new index. See
|
|
{ref}/transforms.html[{transforms-cap}] and
|
|
{ref}//transform-apis.html[{transform-cap} APIs].
