Remote Iterator Server

Remits is a persisted stream database that allows you to query via intuitive map, reduce, and filter functions called Iterators.

Remits is built to be fast, lightweight, and reliable. It is intended to be easy to setup, manage, and reason about.

Remits is still very young. Feel free to play around with it, contribute, and help define it's future...but don't use it in production yet.

To build the server:

git clone https://github.com/badtuple/remits
cd remits
cargo build --release --bin remits

To build the CLI Client for testing/administration:

cargo build --release --bin client

Overall design documentation is hosted in the design folder in the root of this repo.

From a high level though, Remits only has 3 primary constructs:

1. A Message is a list of bytes stored in a Log.
2. A Log is a persisted, append-only list of Messages.
3. An Iterator applies a Map/Filter/Reduce operation over a Log or Iterator and returns the modified Messages.

A client will be able to push Messages to a Log, and then create an Iterator over it to query them back out.

Each Message has an Offset which represents it's index in the Log. When using an Iterator, you can choose to iterate from the beginning, the end, or a certain Message's Offset. This allows you to store your place in an Iterator and then resume from that spot at a later time.

Want to contribute to Remits? Feel free to jump into our chat or open a github issue. We'll be happy to help find a good place to get started! Remits is still young, so there's alot of low hanging fruit and definitional work to do.

For now, if you have any questions please open up a github issue.
