I have been working on a project, tentatively called Q4A (Query for Accumulo). Another possible name is ASQ (Accumulo Streaming Query) [discus].
This is a streaming query as the query is completed via a stream, should never group data in memory. To batch, intermediate results would be written back to Accumulo temporarily. The *primary goal* is to have a complete SQL implementation native to Accumulo. *Why do this?* I am getting tired of writing bad java code to query a database. I would rather write bad SQL code. Also, people should be able to get queries out faster and it shouldn't take a developer. *Native To Accumulo*: - There should be no special format to read a database created by Q4A - There should be no special format for Q4A to query a table - All tables are tables available to Q4A - Any special tables, are stored away from the users databases (indexes, column definitions, etc) *Other Goals*: - Implement the entire SQL definition (currently all of SQLite) - Create JDBC Driver/Server - Push down Expressions to the Tablet Servers - Install-less queries, use Q4A jar directly against any Accumulo Cluster ( less push-down expressions) - documentation :o - testing ;) *Does it work?* Not yet, the project is still a work in progress. and I will be working on it at the Accumulo Summit this year. Progress is slow as I am getting married in about a month and some change. *Questions:* If you have questions about Q4A as here, I will be at the Accumulo Summit @ ClearEdgeIT Table and Hackathon. *WHERE IS TEH LINK?!1!* Oh.... here: https://github.com/agwells0714/q4a -- *Andrew George Wells* *Software Engineer* *awe...@clearedgeit.com <awe...@clearedgeit.com>*
