It has a build system, but is missing an INSTALL file :( I have now added one. > by the way HDF5 has its own table API, it seems you did not use it > > https://support.hdfgroup.org/HDF5/doc/HL/RM_H5TB.html Correct. The tablator library reads the metadata to set up the column types and the number of rows. Then populating the table is a binary read(). I needed the absolute best performance, and this strategy avoids the need to parse each column and row. This puts some limits on what kind of HDF5 tables it can read. For example, it can not handle variable length strings. Cheers, Walter Landry
