I have a question in these day. *Can we improve Tajo performance further than now?* Since Tajo is well architectured, each module can be improved independently. >From the SQL parser to the network part, there will be many candidates to improve. If you didn't try due to lack of time to implement, you can share your idea. As a Tajo community member, please feel free to comment anything. We can discuss and create more issues for that. When we release Tajo 0.11, I believe that Tajo passes TPC-DS 99 queries (up to now 26 queries) and Tajo speed becomes more faster. It depends on our coding speed. :-) Best regards, Dongjoon. PS.
