Elasticsearch Client Reuse Companion
FreeSearch Client Reuse
Warning icon on a new RestHighLevelClient(...) (legacy client) or new ElasticsearchClient(...) (modern Java client) construction written inside a regular method body: Elastic's own documentation states "only one single instance should be created" and that it's "best practice to create your RestHighLevelClient instance as singleton" since "each instance creates its own connection pool". Buildi
The gap it fixes
new RestHighLevelClient(RestClient.builder(host)) compiles fine and returns a working client — call it once per request handler and each call quietly opens a brand new connection pool instead of reusing the one the application actually needs.
