Allowed ValuesDuration
CategoryData Lifecycle
Note

Leave at the default value (1 month) in almost all cases. Setting it to a small value can cause the cluster to not initialize with the correct historical state. Only increase this value (never decrease).

Detailed Explanation:

Defines how far back the system looks to correctly place data into the appropriate Gen1 time partition and to reconstruct the correct historical state during initialization.

Recommendation: Leave at 1 month (default) for all deployments.
