> 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
> Priority: Not a Priority
> Labels: auto-deprioritized-major, auto-deprioritized-minor
>
> 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.
> The cache needs to be reloaded periodically for update。
> Limitations：
> 1. It's suitable for scenario that users don't care the lateness so much,
> periodically updating can satisfy them.
> 2. The “ALL” cache needs more memory, so it's suitable for small dimension
> table.
