TingWuHuang commented on FLINK-20460:
-------------------------------------
We have recently completed development of this feature and found that only
version 2.0 supports async client,but HBASE 1.0 version doesn't provide async
methods. .So there are now three ways to do this: first, define a thread pool
call to the synchronous client to simulate an asynchronous request; The second
only Hbase2.2 connector uses asynchronous requests.The third kind of
asynchronous client that introduces external implementation, such as
Asynchbase. However, the functions they provide can only retrieve column data
for the column family one at a time. From the above analysis, maybe the first
way is better.If you agree, could you please assgin it to me. Thank.

> Support async lookup for HBase connector

> Key: FLINK-20460
> URL: https://issues.apache.org/jira/browse/FLINK-20460
> Project: Flink
> Issue Type: New Feature
> Components: Connectors / HBase, Table SQL / Ecosystem
> Reporter: Jark Wu
> Priority: Major
>
> Currenlty, {{HBaseRowDataLookupFunction}} implements {{TableFunction}} which
> is a sync operation. Would be better to have an {{AsyncTableFunction}}
> implementation which has better performance.
