Description

Set a Time-to-Live (TTL) on your mirrored Azure Cosmos DB data in OneLake, independent of the TTL on your source container. Retain analytics history in OneLake longer than the source, or expire mirrored data sooner to control storage and meet retention policies. This brings retention parity with Azure Synapse Link, making it easier to migrate analytics workloads from Synapse Link to Fabric Mirroring.
