Query allocator and evaluation allocator were different.
After analysis, was determined they should be the same, this will help
future development reduce TypeValue copies during queries.
Changes:
- Common allocator, PoolResource backed by MonotonicResource
- Optimized Pool, now O(1) alloc/dealloc as all chunks in Pool form a single
free list
- 2nd PoolResource, using bin sizing, not as perfect for memory usage but
O(1) bin selection
- Now have jemalloc's background thread to make sure decay and return
to OS happens
- Optimized ProperyValue to be faster at destruction/copy/move
- Less temporary memory allocations
- CSV reader now maintains a common line buffer it reuses on line reads
- Writing out bolt values, now reuses a values buffer
- Evaluating an int no longer makes temporary strings for errors it most
likely never throws
- ExpandVariable will reuse existing edge list in frame it one existed
- Remove the e2e that did concurrent mgp_* calls on the same transaction
(ATM this is unsupported)
- Fix up the concurrent mgp_global_alloc test to be testing it more precisely
- Reduce the memory limit on detach delete test due to recent memory
optimizations around deltas.
- No longer throw from hook, through jemalloc C, to our C++ on other
side. This cause mutex unlocks to not happen.
- No longer allocate error messages while inside the hook. This caused
recursive entry back inside jamalloc which would try to relock a
non-recursive mutex.
