> CQSI maintains a client-side metadata cache for tables.
> UPDATE_CACHE_FREQUENCY is a property which can be set on tables and used to
> decide when to update a table's metadata in the client-side cache. If the
> UPDATE_CACHE_FREQUENCY is set to 0, a tables's metadata should always be
> retrieved by getting the latest metadata from the server.
> Currently, tables with UPDATE_CACHE_FREQUENCY set to 0 are retrieved from the
> server each time they are accessed for a query or mutation. After every
> retrieval from the server, the old table ref in the cache is removed and the
> new one is inserted unnecessarily.
> [MetaDataCachingIT#testCacheShouldBeUsedOnlyForConfiguredTables()
> |https://github.com/apache/phoenix/blob/master/phoenix-core/src/it/java/org/apache/phoenix/query/MetaDataCachingIT.java#L170]can
> be used to confirm that the cache is used only for tables with non zero
> update cache frequency. This test is currently ignored.
