Please Tell me about the need for clustering in ElasticSearch.Please tell me about EFS, which outputs PEGA and Stream logs.

Since multiple development environments are required for testing, it is assumed that the namespace is split and two pega-web and pega-stream are built.

The premise is to build one EFS for PEGA log output and one for stream log output.

For such a configuration, how many EFS should I build?

I would like to build one for PEGA log output and one for stream log output, and separate folders by specifying the log output destination. Is it possible?

Please let me know if there are any additional steps required.

Also, do I need to build two EFSs each for PEGA log output and stream log output?

If so, what is the reason?

Also, please tell me the steps to configure log output when two EFSs are configured.
