Call when shard reallocation occurs


(ElasticSearch Users mailing list) #1

Hi,

Is it possible to have my custom callback function defined and invoked by
ES whenever it moves a shard from one node to another?

Thanks,
Sandeep

AFAIK, there is no way to achieve such functionality.

The only way I have figured out have similar functionality is to write a
plugin with a cluster state listener and have the plugin reach out to some
external service.

Cheers,

Ivan

Thanks, Ivan. Appreciate it. I will take a look at 'ClusterStateListener'.
Meanwhile, if you have any ready reference available for this, like doc or
example code, please share. Thanks!
