Class MultiTenancyMigration

java.lang.Object

io.camunda.zeebe.engine.state.migration.to_8_3.MultiTenancyMigration

All Implemented Interfaces:

MigrationTask

public class MultiTenancyMigration
extends Object
implements MigrationTask

This migration is used to extend the data with tenant information. Before this migration, no tenant information was stored in the state. Therefore, we're considering all existing data to be part of the default tenant.

This migration will set the tenant id of all existing data to the default tenant id. Both in values and in keys. When the key has changed, the data is moved to a new column family.
