Elastic Stack Elasticsearch

Hi all,
With reading about the source code of elasticsearch,I (a beginner
with ES) cannot easily figure out the whole flow.
I cannot find out how index data of shard or replicat migrates from one
node to other node when relocation of shard or replica.
Thanks for any tips or pointers.

I want to know which class is responsible for migrating index data from one
node to other node.

Thanks.

That's somewhat complicated, involves many different classes and probably
not the best place to start learning about ES. Are you trying to resolve
some particular issue or just curious about how things work? To answer your
question, if you are interested in the actual process of moving index
pieces from one node to another you take a look at RecoveryTarget and
RecoverySource in the org.elasticsearch.indices.recovery package.

Yes, I'm curious about how things work.It seems developer guide or
references is missing.
