as the title said, I'm confused what does max_connections really do? it seems es client didn't support this param.
the rally command:
esrally race --pipeline=benchmark-only --track=test --target-hosts=$target_hosts --challenge=append-no-conflicts --track-params="bulk_size:10000,bulk_indexing_clients:32,number_of_replicas:1,number_of_shards:1" --client-options="timeout:180"
the rally log:
the doc said:
es didn't exposed this parameter to the user
so what does the rally with this param do?
