Description

This Jira is for a proposed change to the AIO "legacy" store in the Qpid C++ Broker.

Rather than pre-allocating store files in a fixed-size ring buffer (per queue), the linear store allocates files to queue journals on an as-needed basis, freeing them to a free-pool when no longer needed (i.e. all stored messages have been dequeued).

The development is ongoing in a branch called "linearstore".
