FAQs

What Python versions are supported?

Python 2.6 and 2.7. It should be trivial to port to Python 3.x, but I haven't tried that out as yet.

What dump file versions are supported?

All Versions. We have unit tests for versions 2 through 5.

Why doesn't expiry datetime match what's in the dump file?

The dump file stores the unix time in milliseconds precision. This does not have the timezone information. The parser converts this unix time into UTC. Your local clock may or may not be running UTC, and hence the difference.

If you know the timezone used while saving records in redis, you can always convert the UTC time back to the correct timezone.

Why doesn't reported memory match actual memory used?

The memory reported by this tool is approximate. In general, the reported memory should be within 10% of what is reported by info

Also note that the tool does not (and cannot) account for the following -

1. Memory used by client buffers
2. Memory used for pub/sub
3. Redis process overheads

What else can I do with this parser?

1. Export redis into a relational database like MySQL
2. Export redis into a full text search engine like solr or amazon cloud search, so that you can do (almost) real time, full text search.
3. Merge or split dump files. This is useful if you using several instances of Redis and shard your data
4. Build a UI/Explorer for the data in Redis
5. Build a tool that recommends changes that would reduce memory usage. The tool can recommend appropriate values for settings in redis.conf. It can also detect small strings that should instead be stored in a hash. Several other interesting possibilities exist.
