Thanks for your quick reply. I try to build qpid and found there is a linearstore. I can not find documents for it. What is the difference between it and legacystore? Which one should I prefer? Or just point me where I can find these information.
The legacystore is the older implementation. With it, every queue has to be sized upfront, and it can't grow beyond that size. The linearstore is a newer implementation that removes this limitation by using a common pool of page files, and thus allows a given queue to grow as needed.
You can choose which to build via the cmake options BUILD_LINEARSTORE, BUILD_LEGACYSTORE.
I will need to defer to Kim, the author of these stores, for any more detailed information.
