question about 1.10 scheduling, swmr concurrency

Hdf-forum archives

Hello,

I wrote about this earlier...
I need in the near future a new file format for our measurement
instruments, and I consider hdf5 and sqlite.
A "must have" for my project is swmr (single writer multiple users) concurrency.
My favorite is hdf5 especially for performance reasons, but the swmr
feature is only announced in older messages for the version 1.10...
and I still don't find any development version in the downloads.
Since last version (3.7) sqlite implements this kind of concurrency
(wal mode), so I'm at a point where I have to reconsider my options...

Is there a more recent estimation about it? Or even better, is it
possible to get a version for testing/evaluating?

Thanks,
Gabriel

  We're still shooting for a beta release of 1.10.0 around November of this year. I can point you at some alpha quality code, if you are interested in test-driving what's available now and won't keep any of the files produced.
