Elasticsearch breaking changes
editElasticsearch breaking changes
editThis list summarizes the most important breaking changes in Elasticsearch 7.2.1. For the complete list, go to Elasticsearch breaking changes.
Discovery changes
editOnly a single port may be given for each seed host.
editIn earlier versions you could include a range of ports in entries in the
discovery.seed_hosts list, but Elasticsearch used only the first port in the range and
unexpectedly ignored the rest. For instance if you set discovery.seed_hosts:
"10.11.12.13:9300-9310" then Elasticsearch would only use 10.11.12.13:9300 for
discovery. Seed host addresses containing port ranges are now rejected.
Index lifecycle management (ILM) deprecations
editAn ILM poll interval of less than one second is deprecated.
editSetting indices.lifecycle.poll_interval to less than one second (1s) is now
deprecated. If the indices.lifecycle.poll_interval cluster setting is too low,
it can cause excessive load on a cluster.
To avoid deprecation warnings, use a setting value of 1s or greater.
Ingest pipeline changes
editThe user_agent ingest processor’s ecs parameter is deprecated.
editThe ecs parameter for the user_agent ingest processor is deprecated and will
be removed in 8.0. In 8.x, the user_agent ingest processor will only return
Elastic Common Schema (ECS) fields.
To avoid deprecation warnings, remove the parameter from your ingest pipelines.
