setUpStorageProvider

public void setUpStorageProvider(StorageProviderUtils.DatabaseOptions databaseOptions)

Description copied from interface: PartitionedStorageProvider

This method allows to reinitialize the StorageProvider. It can be used if you are using Flyway or Liquibase to setup your database manually. By default, this method is automatically called on construction of the StorageProvider

Parameters:

databaseOptions - defines whether to set up the StorageProvider or validate whether the StorageProvider is set up correctly.
