Hello, Thank You for Your kind feedback!
I began coding and I uploaded the source code written so far on the website at https://sites.google.com/site/gsoc2013tajo34/home/validation. It is uploaded as an attachment and there are some other files with tests I've done. I continue with the optimization of changing outer joins to inner joins, whenever suitable , in method rewriteOuterJoin, as proposed in EXT 3.3 in the Software Design Document. In the following days I shall upload this source code as well. Please be kind to give me feedback of whether You are content with the source code I wrote so far and if You agree on the processing performed so far. Yours sincerely, Camelia -------------------------------------------- On Wed, 7/3/13, Hyunsik Choi <[email protected]> wrote: Subject: Re: [GSoc2013] - Outer Join To: "tajo-dev" <[email protected]> Date: Wednesday, July 3, 2013, 10:04 PM Camellia, Since you submitted your proposal, I've been amazed at your work.
