Bowen Li updated FLINK-16781: ----------------------------- Description: Currently there's no built-in cache mechanism for LookupableTableSource. Developers have one of the following options: 1) build their own cache 2) use external cache services, like redis, memcached, etc, which Flink unfortunately doesn't have an out-of-box lookup function either 3) give up caching and bear with poor lookup performance Flink should provide a generic caching layer for all the LookupableTableSource to take advantage of. cc [~ykt836] [~jark] [~lzljs3620320] was: Currently there's no built-in cache mechanism for LookupableTableSource.
