package com.arjuna.ats.internal.arjuna.objectstore;
The basic action store implementations store the object states in a separate file within the same directory in the object store, determined by the object's type. However, as the number of file entries within the directory increases, so does the search time for finding a specific file. The HashStore implementation hashes object states over many different sub-directories to attempt to keep the number of files in a given directory low, thus improving performance as the number of object states grows. Currently the hash number is set for both user hashed stores and action hashed stores.
