How redislite works

redislite provides enhanced versions of the redis.Redis() and redis.StrictRedis() classes.

These enhanced classes accept the same arguments as the corresponding redis classes.

Both enhanced classes accept one additional optional argument, which is the filename to use for the redis rdb file.

These enhanced classes provide the following additional functionality:

• They configure and start an embedded copy of the redis server running on a unix domain socket in the redislite temp directory for the communication to the redis service.
• TCP communication is disabled by default, unless server settings are passed to enable it.

• The classes have two additional attributes:

  • db - The path to the db backing file for the redis instance.
  • pid - The process id (pid) of the embedded redis server.

• If the db argument is passed and there is another redislite object using that db, it will create a new connection to that redislite instance.
• The redis server for a redislite object is shutdown and it’s configuration is deleted when the last redislite connection to the server is terminated.
• If a redis rdb filename is specified, the cleanup will not delete the rdb file so it can be used again.
