> Project: Flink
> Issue Type: Improvement
> Reporter: lincoln lee
> Priority: Major
> Labels: pull-request-available
>
> FLIP-234 introduced a LOOKUP hint which support suggest planner to use sync
> or async lookup function by hint option 'async' = 'false' or 'true', also the
> planner prefers an async lookup when a connector has both sync and async
> lookup capabilities.
> As discussed in the mailing list before
> ([https://lists.apache.org/thread/9k1sl2519kh2n3yttwqc00p07xdfns3h]), this
> 'lookup.async' option should be deprecated and refactor the hbase table
> source to expose both async and sync lookup capabilities to planner, so that
> users can switch to use the new query hint
