  • bustub

    The BusTub Relational Database Management System (Educational)

    • Andy Pavlo's courses at CMU teach database internals (e.g., https://15445.courses.cs.cmu.edu/fall2020/). In the project coursework, you build features for a teaching relational database called BusTub (https://github.com/cmu-db/bustub).

  • PostgreSQL

    Mirror of the official PostgreSQL GIT repository. Note that this is just a *mirror* - we don't work with pull requests on github. To contribute, please see https://wiki.postgresql.org/wiki/Submitting_a_Patch

    • In Postgres this is done through "access methods" and the storage layer. You will probably also need to analyze how a query is parsed and converted to a binary format, then handed over to the executor

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
