CxLeaderboard - a comprehensive leaderboard library
I wrote a library for building leaderboards. Would love any feedback. This is the list of features from the readme:
- Ranks, percentiles, any custom stats of your choice
- Concurrent reads, sequential writes
- Stream API access to records from the top and the bottom
- O(1) querying of any record by id
- Auto-populating data on leaderboard startup
- Adding, updating, removing, upserting of individual entries in live leaderboard
- Fetching a range of records around a given id (contextual leaderboard)
- Pluggable data stores:
EtsStorefor big boards,TermStorefor dynamic mini boards - Atomic full repopulation in ~O(2n log n) time
- Multi-node support
- Extensibility for storage engines (
CxLeaderboard.Storagebehaviour)

I wanted to link it but the website was down for me as well … You can do erl -man gb_trees in your shell.
