Consistency Testing

Offline Testing

Test Purpose

Test data consistency between the source and target redis.

Test Environment

  • Machine: 16 cores, 32GB memory
  • Data Structures: key(set/del), set(sadd, spop), list(lpush, lpop), incr, hash(hset, hdel)
  • QPS: 4500
  • Redis: Source (3 masters, 3 slaves), Target (3 masters, 1 slave)
  • Data Volume: 260,000 keys
Sync Type Case Test Method Test Result Description
Transaction Source Master-Slave Switching Execute cluster failover force in redis, compare source and target redis via redis-full-check tool Passed Consistent data after 10+ switches
Transaction Target Master-Slave Switching Execute cluster failover force in redis, compare source and target redis via redis-full-check tool Passed Consistent data after 10+ switches
Non-Transaction Source Master-Slave Switching Execute cluster failover force in redis, compare source and target redis via redis-full-check tool Passed Consistent data after 10+ switches
Non-Transaction Target Master-Slave Switching Execute cluster failover force in redis, compare source and target redis via redis-full-check tool Passed Consistent data after 10+ switches
Slot migration Migrating source redis slots Scale up/down source redis, or migrate slots Failed A little bit of data is consistent
Slot migration Migrating target redis slots Scale up/down source redis, or migrate slots Passed

For the case that data is inconsistent after migrated source redis slots, please refers to the solution inconsistency solution
