Hi all, Currently master code of carbondata works with *prestodb 0.217* We all know about competing *presto-sql* also. Some of the users doesn't want to migrate to *presto-sql *as their cloud vendor doesn't support presto sql (Example, AWS EMR, Huawei MRS, AZURE services except HDInsights still comes with *presto db*)
So, 1. carbondata need to support both of them ? 2. carbondata need to maintain two modules ? one for prestodb, one for prestosql, may be need to extract common code (big effort) 3. At a time carbondata can support only version of prestodb and presto-sql. Every 15 days they release version and our integration is not based on SPI (not as stand alone connector), we extended hive connector interface. so, every few releases, carbondata and presto integration code need to modify. This can be a bigger problem for maintenance. And this is about read support, when we handle write support need to take care about all the above points. Thanks, Ajantha
