xConnect Scalable Reads

xConnect Scalable Reads uses read/write requests between xConnect and the Primary Collection database shard cluster and read-only requests between xConnect and the Secondary Collection database shard cluster.

The xConnect Scalable Reads feature lets you offload the primary database from read-only workloads using one of the read-only/secondary replicas.

It is a configured replication for the collection database shard cluster. The read scale-out allows a load balance of complex read workloads without affecting the primary OLTP workload.

xConnect read scale-out is available for both SQL On-Prem and SQL Azure collection database.

Important

The MongoDB provider does not support scalable reads.
