Hi, Thanks for the answer. I wasn't aware that the chunk_size is scaled with the record size.
A few clarifications. What I mean by that "the column type is not fixed" is that the fields (or what I referred to as "columns") of the compound type are not known at compile time (there is no predefined C struct), but will be fixed at runtime when the table is created. The problem I have is when I create a large compound type with a lot of fields, the performance degrades quite substantially. At some size, it will even refuse to build this compound type. -- View this message in context: http://hdf-forum.184993.n3.nabble.com/Using-H5TB-for-large-tables-tp4025782p4025795.html Sent from the hdf-forum mailing list archive at Nabble.com. _______________________________________________ Hdf-forum is for HDF software users discussion.
