Conclusion

  • Not sure what ¬†happend on YbDB OLTP
  • CrDB at max latency will be unstable
  • Memory Usage:
    • TiDB > YbDB3 > YbDB1 > CrDB
  • Table
    • C: CrDB = TiDB > YbDB1 > YbDB3
    • D: CrDB = TiDB > YbDB1 > YbDB3
  • Row
    • C: YbDB1 > TiDB > CrDB > YbDB3
    • R: CrDB > TiDB > YbDB1 > YbDB3
    • U: CrDB > YbDB1 > TiDB > YbDB3
    • D: CrDB > YbDB1 > TiDB > YbDB3

Overall

CrDB > TiDB > YbDB
