Hi, In a cross region setup using the S3 data store, it may make sense to leverage the Cross-Region auto replication of S3 buckets [0,1].
In order to avoid data replication issues it would make sense IMO to allow configuring the S3DataStore with two S3 buckets, one for writing and one for reading. The writing bucket would be shared among all instance (from all regions) while the reading bucket would be in each region (thus decreasing the latency). The writing bucket would auto replicate to the reading buckets. Has this been tested already ? Generally, wdyt ?
