Hi All,

I am currently Project Lead at Sicap, a Swiss company which designs softwares for mobile operators and the mobile network world in general.

We are going to use a BTree library to index entries of csv files. We have identified JDBM library (http://jdbm.sourceforge.net/) and we have seen that you are currently using it in Open JMS.

As there is no more tracker activity on this project and it seems that it is the same thing for support, we would like to know if JDBM is stable:

è       Have you encountered problems when you use this library in multithreaded mode: Several concurrent inserts at a time?

è       What is the behaviour of the library when we shut down with emergency? Is it robust? By this way, does BTree file could be corrupted?

è       Do you encountered performance lack in some cases?
è       Is there some limitations or lacks: Size of the index chain, cache size etc ...
è       Etc ...

We are very interested on your feedbacks and experiences on JDBM library usage ?

Thank’s a lot,

Kind Regards,

Florent GRATTA
