Persistent get delta #173

Closed songweijia closed 4 years ago

songweijia commented 4 years ago

New Feature:

Persistent::getDelta(version_t ver) allows efficient handling of a delta log entry instead of reconstructing the whole state at version 'ver'. This feature is useful for efficiently tracking versions of a Key in Cascade.

Improvements and bugfixes:

Rewritten Persistent documentation
Bugfixes for zero-copy version of Persistent::get(), which didn't work.
Minor fixes for RVO warnings with GCC-9

I want to merge the pull request I made about 10 days ago. This feature is required for efficient Cascade LINQ API. I verified with regression test that this update will not change the performance of core derecho performance. Please let me know if you guys agree this merge. @sagarjha @mpmilano @etremel

Yes, this looks good to me.

Thanks, Edward! I guess should merge it this weekend if there is no more feedback.
