问题
I'm looking for a little assistance in Scala similar to that provided by pyTables. PyTables is a package for managing hierarchical datasets and designed to efficiently and easily cope with extremely large amounts of data.
Any suggestions?
回答1:
I had a quick look at pyTables, and I don't think there's anything remotely like it in Scalaland (or indeed Javaland), but we have a few of the ingredients necessary to make it a possibility if you want to invest the time:
- scala.Dynamic to do idiomatic selection on data-driven structures
- A bunch of graph databases to provide the underlying navigational persistence substrate (I've had acceptable results from OrientDB, which has a better license than most)

PyTables is a python implementation of HDF5 with some added niceties to let you work on it in a pythonic way, and get good indexing support. I'm not sure if there's a package implemented in a similar way in Scala, but you can use the same HFD5 based hierarchical data storageusing the HDF5 implementation in Java: HDF Java
