I'm very interested in understanding how shards are managed in elasticsearch. I mean I want to understand from basics to everything that we should know for designing and maintaining a elasctisearch cluster in production.
As of now, I've a baisc knowledge but I want to understand more like how many shards are created for every index, how much max data each shard can allocate , how to design to improve the performance like these I have many questions?
Can you please suggest me the best resources to understand shard and index management in ES.
Also are there any books for the same. would be happy, if avaialable.
Thanks for your time as always
