.alter-merge database sharding policy
Change the database sharding policy. Use the sharding policy to manage data sharding for databases and tables.
The sharding policy defines if and how Extents (data shards) in the Azure Data Explorer cluster should be sealed. When a database is created, it contains the default data sharding policy. This policy is inherited by all tables created in the database (unless the policy is explicitly overridden at the table level).
Syntax
.alter-merge database DatabaseName policy sharding ArrayOfPolicyObjects
Arguments
DatabaseName - Specify the name of the database. ArrayOfPolicyObjects - An array with one or more JSON policy objects.
Returns
Returns a JSON representation of the policy.
Example
The following command changes a single property for the sharding policy for a database:
.alter-merge database MyDatabase policy sharding
@'{ "MaxExtentSizeInMb": 1024}'
