Roman Nozdrin	4c26e4f960	MCOL-4912 This patch introduces Extent Map index to improve EM scaleability ... EM scaleability project has two parts: phase1 and phase2. This is phase1 that brings EM index to speed up(from O(n) down to the speed of boost::unordered_map) EM lookups looking for <dbroot, oid, partition> tuple to turn it into LBID, e.g. most bulk insertion meta info operations. The basis is boost::shared_managed_object where EMIndex is stored. Whilst it is not debug-friendly it allows to put a nested structs into shmem. EMIndex has 3 tiers. Top down description: vector of dbroots, map of oids to partition vectors, partition vectors that have EM indices. Separate EM methods now queries index before they do EM run. EMIndex has a separate shmem file with the fixed id MCS-shm-00060001.	2022-05-04 12:59:16 +00:00
