Java 17 features in Elasticsearch code base #81820
Description
This is a meta issue for tracking Java 17 features implementation in Elasticsearch. The work is composed of the following tasks:
- Pattern matching for
instanceof. Tasks are divided between folders under https://github.com/elastic/elasticsearch. The split also takes into consideration that some of the above mentioned folders do not contain anyinstanceofoccurrences that can be transitioned to pattern matching.-
