Lijie Wang created FLINK-17178:
----------------------------------

             Summary:  Provide "ALL" cache strategy in LookupFunction
                 Key: FLINK-17178
                 URL: https://issues.apache.org/jira/browse/FLINK-17178
             Project: Flink
          Issue Type: New Feature
          Components: Connectors / Common
            Reporter: Lijie Wang


We provide "ALL" cache strategy mentioned in FLINK-13252, motivation as follow:

Maintain the entire dimension table in memory to improve performance. There is no IO overhead when we lookup the cached table. Reload dimension table periodically for update, and we can reload asynchronously with little IO delay.
