Currently elastic search allows you to specify custom shards for its regular indices , but when those indices are rolled up there is no way to specify shard and replica setting for the rollup index.
Elasticsearch by default assigns
shards :5
replica:1
And there is no way to change this after creation of index or while specifying rollup job
Neither there is a way to manually create a rollup index without using rollup job
Is there any plan to introduce such capabilities in future ?
