Breaking changes
editThe following changes in Elasticsearch 8.10 might affect your applications and prevent them from operating normally. Before upgrading to 8.10, review these changes and take the described steps to mitigate the impact.
There are no notable breaking changes in Elasticsearch 8.10. But there are some less critical breaking changes.
Cluster and node setting changes
editRemove the unused executor builder for vector tile plugin
Details
The threadpool called vectortile
is a left over from the original development of the vector tile search end point and it is used nowhere. It can still be a breaking change if it is configured on the elasticsearch yml file, for example by changing the threadpool size thread_pool.vectortile.size=8
'
Impact
In the case the threadpool appears on the yaml file, Elasticsearch will not start until those lines are removed.
Java API changes
editChange pre-configured and cached analyzer components to use IndexVersion instead of Version
Details
This PR changes the types used to obtain pre-configured components from Version to IndexVersion,
with corresponding changes to method names.
Prior to 8.10, there is a one-to-one mapping between node version and index version, with corresponding constants in the IndexVersion class. Starting in 8.10, IndexVersion is versioned independently of node version, and will be a simple incrementing number. For more information on how to use IndexVersion and other version types, please see the contributing guide.
Impact
Analysis components now take IndexVersion instead of Version
