Google Summer of Code at OLake
Work with OLake on a 12+ week open source project, guided by mentors. Apply with a strong proposal and build the future of data lakehouse replication.
What is GSoC?
Google Summer of Code is a global program where contributors work with open source organizations on a 12+ week project, guided by mentors.
At OLake, GSoC contributors help us improve the fastest open-source data replication tool—adding observability, improving CDC semantics, and extending our Apache Iceberg integration. You'll work alongside maintainers and ship code that powers real data pipelines.
Where to start
Before writing a proposal, we recommend:
- Read OLake docs (especially the architecture and contributor docs)
- Set up the OLake dev environment locally
- Join the OLake community channels (Slack, GitHub)
- Pick a project idea (Small / Medium / Large) and talk to the mentors early
