Push-down, write tables and PostgreSQL 9.3

Open brunosimioni opened this issue 11 years ago • 8 comments

Atri,

PostgreSQL 9.3 FDW API provides great new features, like push-down matches, writeable table and performance issues (in an overall pov).

Is there any activity plan to migrate JDBC_FDW to PostgreSQL 9.3? Here we are facing some performance issues (1s+/query), besides all database resources lost, being stucked at 9.2 version.

Can we help you in some way?

Thanks!

Hi,

Thanks for mentioning it.

We need to add to support for 9.3. However currently I am very busy in my job and hence would not be able to directly work on it.

It would great if somebody could work on it with me sp that my life becomes easier.

Thanks for offering your help.

Regards,

Atri

Quick note: You should continue to support this library. If you are going to abandon it, please inform people of that so that they can avoid using it...unsupported software generally should be avoided.

I am not abandoning it. I will add those features but will need some time

Would your draw/identify some points to change to get an updated release? Maybe we can help your if your guide us.

What do you think, @merlinm?

Best

The way FDW API is structured unfortunately at present this work is a large copy/paste job from pgsql fdw. That being said it shouldn't be too difficult to do presuming the deparsing code is compatible with the server's SQL dialect (I'm thinking it mostly will be).

merlin,

I ask for Atri's guidance, just because I guess he have some points about his own project and ideas. Something around trying to make jdbc_fdw better than a copy&paste job, or even, how we can improve it's perfomance. (since it's a copy & paste from a reference implementation, it should - theorically - perform good. it's actually not happening, and it should be repaired).

Would you clarify how you can help us in this process, please? Are you directly involved in this project or even knows how it could works with PostgreSQL 9.3?

I'm a current user of jdbc_fdw project and, unfortunatelly I had to implement a sync method (turning a foreing table in a local table via insert/update, to get rid of performance issues. That's not a good solution, but, since jdbc_fdw gives me 1, 2 seconds delay, I have no other option.

Best, Bruno.

I can spend some time next week to think what we can do. Let's sit down and plan then if it's fine with you H Sent from my iPad

It's been about a year, is this issue dead and is the project unmaintained or will this happen at some point?
