elasticsearchHow do I use Elasticsearch with ZGC?
Elasticsearch can be used with ZGC (Z Garbage Collector) to improve the performance of your Java applications. To use Elasticsearch with ZGC, you must first enable the ZGC JVM option. This is done by adding the following line to your jvm.options file:
-XX:+UseZGCThis will enable the Z Garbage Collector for your Elasticsearch cluster. Once enabled, you can then tune the ZGC parameters to optimize the performance of your Elasticsearch cluster. For example, to set the maximum heap size for ZGC, you can use the following line in your jvm.options file:
-XX:MaxHeapSize=<size>Where <size> is the maximum heap size in bytes. You can also tune other ZGC parameters such as the pause target, the number of threads, and the number of regions.
In addition to tuning the ZGC parameters, you should also ensure that Elasticsearch is configured to take advantage of ZGC. This includes setting the indices.memory.min_shard_index_buffer_size and indices.memory.max_shard_index_buffer_size settings, as well as setting the node.max_local_storage_nodes setting.
