redli VS redimo.go

The Redis cluster on Digital Ocean has TLS enabled. This means you won't be able to connect to it using the redis-cli without configuring stunnel. Alternatively, you can use redli to connect to a Redis cluster with TLS enabled.

Did this for DynamoDB over the pandemic. Helped me learn both the Redis API and DynamoDB. https://github.com/dbProjectRED/redimo.go

Want to do the same thing with Postgres as well.

The Redis API and data structures are really nice and have been tuned to be useful in a wide variety of situations. Implementing these APIs is different concurrent, compute and storage models is a nice way to learn them and get options open.

The way that I learnt the ins and outs of DynamoDB (and there is a lot to learn if you want to use it effectively) is by implementing all the Redis data structures and commands on it. That helped understand both systems in one shot.

The key concept in Dynamo is that you use a partition key on all your bits of data (my mental model is that you get one server per partition) and you then can arrange data using a sort key in that partition. You can then range/inequality query over the sort keys. That’s the gist of it.

The power and scalability comes from the fact that each partition can be individually allocated and scaled, so as long as you spread over partitions you have practically no limits.

And you can do quite a bit with that sort key range/inequality thing. I was pleasantly surprised by how much of Redis I could implement: https://github.com/dbProjectRED/redimo.go

Running a Fly app backed by DynamoDB Global Tables is an option. DDB keeps a copy of your data in all the regions you specify, each Fly instance can connect to the nearest region, and writes are propagated with eventual consistency & last write wins.

And most Redis commands can be mapped to DDB, I worked on a lib to do that.

Redimo this open source project from Sudhir Jonathan that provides a library that allows you to use the Redis API on DynamoDB and bridges the two and translates the Redis API operations into space / time / cost-efficient DynamoDB API calls. Redimo is especially well suited to serverless environments, since there is no pool of connections to handle and DynamoDB is purpose-built for near-zero management use.
