HDB++ schema

General Development
1

Hello!
I want to use HDB++ with tango 8.

But after i checked out repository i have faced some problems.
I have a few questions:
0)Is it a valid repository?

1)There is a new version of create_hdb++_mysql.sql with att_error_desc table separated. But hdb++ extraction libraries (java and c++) doesn’t support this schema. Is is planned to update source code to comply with schema?

2)Is it planned to keep this schema in next release?

3)Another problem is that c++ library doesn’t work with all types (short, float). Will these types be supported?

Hello!

Yes it is… This will be moved to GitHub soon.

Yes, it is planned to update the source code to comply with this new schema.

I think so, unless big issues are discovered with this new schema.

I guess you are talking about the C++ extraction library here?
Maybe Giacomo could comment on this?

Cheers,
Reynald

Thank for your answer!

When a move to GitHub is expected?

We are interested in development of HDB++ and want to contribute to a project.
For now, I could provide a simple patch for java extraction library that comply with a new schema.
Best regards,
Alexander

Hi Alex,

thanks for your patch and proposal to help. I vote for moving HDB++ to github too! It would be great if it could happen soon. I am sure it will happen before the next meeting …

Cheers

No performance tests were done.
