Can PyTables be used in concurrent access scenarios?
It depends. Concurrent reads are no problem at all. However, whenever a process (or thread) is trying to write, then problems will start to appear. First, PyTables doesn’t support locking at any level, so several process writing concurrently to the same PyTables file will probably end corrupting it, so don’t do this! Even having only one process writing and the others reading is a hairy thing, because the reading processes might be reading incomplete data from a concurrent data writing operation.
