各位大佬好,安装的redis版本为5.0.8 ,在测试rdb+aof混合模式下从节点重启是否可以部分同步时,发现只要开启了aof持久化模式,从节点重启还是全量同步,是因为psync2保存的复制id与复制偏移量只保存在rdb文件里的原因吗,如果是这样那是不是开启了aof就不能使用psync2的特性了?,烦请各位指教
参数配置如下:
rdbcompression yes
rdbchecksum yes
dbfilename "dump_6912.rdb"
dir "/redis/redis6912/db"
appendonly yes
appendfilename "appendonly_6912.aof"
appendfsync everysec
no-appendfsync-on-rewrite yes
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
aof-load-truncated yes
aof-use-rdb-preamble yes
replicaof 10.xxx.xxx.xxx 6912
