Re: [jira] [Created] (IGNITE-6769) SQL: prototype for hand-made parser
Hi Ray, Not yet, I think we will heave a roadmap by the end of this year. I hope that by the time of 2.4 release we will have the following: 1) Improve data loading speed [1]. As a part of this activity there is a chance that we will change our implementation of our indexes, so that they no longer depend on H2. 2) Have our own parser capable of handling DDL requests [2], [3] 3) Have a raw prototype of very simple execution engine to reason about possible performance improvements (no ticket yet).

Re: [jira] [Created] (IGNITE-6769) SQL: prototype for hand-made parser
Hi Vladimir, Thanks for the reply. Is there any roadmap for this new execution engine? For example, in version 2.4 the new engine will process select commands and the rest commands will still be handled by H2. -- Sent from: http://apache-ignite-developers.2346864.n4.nabble.com/
Re: [jira] [Created] (IGNITE-6769) SQL: prototype for hand-made parser
Hi Ray, Yes, we are going to gradually move away from H2. This will be long process, so first we create execution engine for simple queries, then for more complex, etc.. Also it is very likely that our current distributed execution engine and co-location model will be reworked somehow.

Re: [jira] [Created] (IGNITE-6769) SQL: prototype for hand-made parser
Hi Vladimir, What's the purpose of this ticket? Does it mean in the future Ignite will have its own SQL parser instead of H2's parser Ignite is using now? -- Sent from: http://apache-ignite-developers.2346864.n4.nabble.com/
