Cube.js pre-aggregation storage layer.
Over the past year, we've accumulated feedback around various use-cases with pre-aggregations and how to store them. We've learned that there are a set of problems where relational databases as a storage layer has significant performance and functionality issues.
These problems include:
UNION ALL queriesJOIN performance across rolled up tablesOver time, we realized that if we try to fix these issues with existing database engines, we'd end up modifying these databases' codebases in one way or another.
We decided to take another approach and write our own materialized OLAP cache store, designed solely to store and serve rollup tables at scale.
To optimize performance as much as possible, we went with a native approach and are using Rust to develop Cube Store, utilizing a set of technologies like RocksDB, Apache Parquet, and Arrow that have proven effectiveness in solving data access problems.
Cube Store is fully open-sourced and released under the Apache 2.0 license.
We intend to start distributing Cube Store with Cube.js, and eventually make Cube Store the default pre-aggregation storage layer for Cube.js. Support for MySQL and Postgres as external databases will continue, but at a lower priority.
We'll also update all documentation regarding pre-aggregations and include usage and deployment instructions for Cube Store.
docker build -t cubejs/cubestore:latest .
docker run --rm cubejs/cubestore:latest
Check out https://github.com/cube-js/arrow/tree/cubestore-2020-11-06 and put .cargo/config.toml in the current directory with following contents:
paths = ["../../arrow/rust"]
It should point to checked out Apache Arrow fork and it'll allow you to build project against locally modified sources.
Cube Store is Apache 2.0 licensed.
