Hi,
We have a hot warm architecture for elasticsearch and have a zone awareness also in place for primary and replica shards.
We have observed that during hot > warm allocation of the index after 2 days, the index gets relocated to different availability zone in the warm node. This transfer to a different availability zone have some performance impact.
How can I make sure that the index goes to warm node in the same availability zone as it was in the hot node so as to get maximum performance during the reallocation?
