Skip checksum validation on database loading process (applicable only for ARM 32/64). Default: false. Experts only. Should be set to true in order to skip checksum verification of modifications in database recovery, if process takes too long (checksum calculation on some ARM machines is somewhat slower sometimes) Although gaining faster recovery time and server startup time, skipping checksum validation may cause later report on corrupted data if one was exists during historical revocery.
