Hello Team,

Could you please help me understand if elasticsearch filter plugin uses cache and if there are performance issues with the plugin.  
I am planning to use this filter plugin forvl data lookup.

Thank you for your help and support.  
Aditya

As far as I know it does not cache any data and as it makes a request per event it tends to be slow and restrict throughput.
