DseClusterBuilderWithMetadataSyncOptions Method

If not set through this method, the default value options will be used (metadata synchronization is enabled by default). The api reference of MetadataSyncOptions specifies what is the default for each option.

In case you disable Metadata synchronization, please ensure you invoke RefreshSchemaAsync(String, String) in order to keep the token metadata up to date otherwise you will not be getting everything you can out of token aware routing, i.e. TokenAwarePolicy, which is used by DseLoadBalancingPolicy and is the default.

Disabling this feature has the following impact:

• Token metadata will not be computed and stored. This means that token aware routing (TokenAwarePolicy, which is used by DseLoadBalancingPolicy and is the default) will only work correctly if you keep the token metadata up to date using the RefreshSchemaAsync(String, String) method. If you wish to go this route of manually refreshing the metadata then it's recommended to refresh only the keyspaces that this application will use, by passing the
  Copy

  keyspace

  parameter.
• Keyspace metadata will not be cached by the driver. Every time you call methods like GetTable(String, String), GetKeyspace(String) and other similar methods of the Metadata class, the driver will query that data on demand and will not cache it.
• The driver will not handle
  Copy

  SCHEMA_CHANGED

  responses. This means that when you execute schema changing statements through the driver, it will not update the schema or topology metadata automatically before returning.
