…17747 (#17831) ref #16141, close #17767, ref #17767 In-memory engine: handle error when getting regions info (#17805) ref #16141 handle error when getting regions info Signed-off-by: SpadeA-Tang <u6748471@anu.edu.au> --- In-memory Engine: Adjust memory settings based on available memory (#17515) ref #16141 This commit adjusts the following in-memory-engine defaults: * `capacity`: Now IME uses 10% of the block cache and takes an equal amount of memory from the system. This is based on tests showing that the IME rarely fills its full capacity. * `mvcc_amplification_threshold`: Change from 100 to 10 which benefit common workloads like TPCc (50 warehouse), saving approximately 20% of unified read pool CPU usage. Also, it addresses two security issues: * Upgrade hashbrown from yanked 0.15.0 to 0.15.1 Signed-off-by: Neil Shen <overvenus@gmail.com> --- In-memory Engine: fix panic when destroy an uninitialized region (#17771) close #17767 IME observes all peer destroy events to timely evict regions. By adding a new peer, the old and uninitialized peer will be destroyed and IME must not panic in this situation.
