1.4 Compare Wiht Redis
With Redis AOF configuration appendfsync everysec, redis basically write data into memeory. However, pika uses rocksdb, which writes WAL on ssd druing every write batch. That comparation becomes multiple threads sequential write into ssd and one thread write into memory.
Put the fairness or unfairness aside. Here is the performance.
2. Cluster (Codis)
2.1 Topology:
WithBInlog&Slave
4 machine * 2 pika instance (Master)
4 machine * 2 pika instance (Slave)
NoBinlog&Slave
4 machine * 2 pika instance (Master)
Slots Distribution:
2.2 WithBinlog&Slave
| Command | QPS |
|---|---|
| Set | 1,400,000+ |
2.3 NoBinlog&Slave
| Command | QPS |
|---|---|
| Set | 1,600,000+ |
2.4 Get Command
| Command | QPS |
|---|---|
| Get | 2,300,000+ |
With or without binlog, for Get command, QPS is approximately the same.
