RE: [Crossdb-developers] CrossDB and LDBC

[<tr...@th...>]

Ya, I like the idea of that option as well.  Especially for people that want to have database independence with programs that are already written.  So they don't have to convert to crossdb, they can just replace the jdbc driver with ldbc.  And for new code, they can just start using crossdb directly.  

You should look into what it would require to merge the two like this and we'll go from there.

Hi Travis,
> Use the ldbc sql parser to parse into a crossdb query/tree, then let
crossdb finish off the db specific sql code. What do you think?
LDBC is currently using Antlr (www.antlr.org) as the parser, and antlr uses
it's own tree representation... not sure how to convert that to crossdb
query/tree. I think on the high level it would be a good idea, but there may
be some nasty technical problems. But probably nothing we can't solve.
I think it would be great if the user can choose the method he would like to
use, writing SQL statements and letting LDBC/CrossDB convert then, or only
using CrossDB to generate SQL for him (for higher performance).

P.S. I will be on vacation until mid next week.
