add SlotStore ObjectStore implementation ---------------------------------------- Key: JBTM-3276 URL: https://issues.redhat.com/browse/JBTM-3276 Project: JBoss Transaction Manager Issue Type: Enhancement Components: Transaction Core Affects Versions: 5.10.3.Final Reporter: Jonathan Halliday Assignee: Jonathan Halliday Priority: Minor Fix For: 5.next The SlotStore provides an alternative ObjectStore implementation that dispenses with the file create/open/close/delete overhead of the FileStore, whilst also eschewing the write batching of the JournalStore. This combination is particularly tailored to new persistent memory hardware, for which the file write sync operation can be done in userspace with low overhead and a high degree of parallelism.
