RedisTimeSeries and AOF

[Van Zyl Kruger]

When I create the following container the timeseries module does not work:

docker run -d -p 6379:6379 -it -v redis_data:/data --name redistimeseries --restart=always redislabs/redistimeseries --appendonly yes

When I remove the --appendonly yes it works fine.

How would I persist the data to a volume mounted to the host, is it supported?

Your help will be much appreciated.

Kind Regars,

Hi Van,

It is supported, can you provide the redis log output?

What do you think?  I love this module but without AOF persistence on Docker I cannot use it and will revert back to my previous sorted set solution.  I work for a large mining company and we use it as our Edge's persistence layer for Data Science and IIoT.

Hi Van,

Because you pass a different set of argument list to redis its overrides the load module argument, here how to pass both load module and AOF flags:
docker run -d -p 6379:6379 -it -v /tmp/redis_data:/data --name redistimeseries --restart=always redislabs/redistimeseries --loadmodule /usr/lib/redis/modules/redistimeseries.so --appendonly yes

Cheers,
Danni.

Thanks that's great.

I previously used Redis Desktop Manager as a UI to show people what Redis is capable of.  Do you know any Redis UIs that supports time series?

Kind Regards,

Van Zyl

RedisInsight has a nice time series view:
