We wrote a python scripts to control redis backup work.
Three Steps to do this work:
1. Create meta database to store which redis instance needs to backup
2. Use scripts to connect to these redis instances with “–rdb” command (remote backup command)
3. Estimate which redis server should be transfered (only slave role redis will be transfered, wait minutes if a bgsave is running)
Backup Scripts: Redis_remote.py
MariaDB TokuDB benchmark on FusionIO ,Compare TokuDB and InnoDB engines.
Benchmark for NVMFS (supports atomic writes ,so we can close double-write option on specific MySQL version )
tips: some Flash-based cards could support large block map , the main idea is to avoid fractured page writes.
In this article, we introduce myawr and mongoawr system .
