Ruby ORM for Cassandra with CQL3
Role in this project:Back-end Developer
Back-end DeveloperContributions:6 commits, 1 comment in 2 days
Contributions summary:Elad primarily contributed to the core functionality of the Cequel ORM, focusing on features related to data persistence and query execution. They implemented the `IF NOT EXISTS` option for insert operations, along with related code modifications. Their work involved changes to the `metal/writer.rb`, `record/persistence.rb` and `metal/inserter.rb` files, and unit tests within `persistence_spec.rb`, which suggests a deep understanding of how the ORM interacts with the Cassandra database. The user also handled options for insert and updates within the Cequel system.
