November 7 HDF5 Working Group Meeting
Agenda (same as last time!):
- HDF5 2.0
- Planning wiki page here: HDF5 2.0 Planning · HDFGroup/hdf5 Wiki · GitHub
- We’ll briefly discuss recent PRs and look at the plans
- Discuss the sparse data RFC (continued from last week)
- If we have time, we’ll start going over this concurrency PR:
From Elena, re: sparse RFC
I suggest that tomorrow I will go through the document and we will discuss and resolve some outstanding questions. The most important ones:
-
Should we use H5Pset_layout or introduce new H5set_sparse_chunk and H5Pset_struct_chunk functions.? Please remember that in the very first RFC I was advocating for reuse of the existing functions, but THG developers voted for new APIs.
-
Should we create special filter functions for structured chunks or use versioned functions that are applicable to both dense and structured chunks?
-
New direct chunk routines. Quincey has reservations about them while we do have use cases from the Synchrotron community. I think bio-informatics community also has use case for VL data storage.
