+** Google Summer of Code 2019: Graph compression
+
+*** Objective
+- Implement graph compression techniques for the main data model
+- Enable in-memory processing of the graph
+
+*** Timeline
+- Research and experiments
+- Compression pipeline and automation
+- API to query the compressed graph
+
+*** Results
+- From 2.5TB down to... *100GB*
+- In-memory access performance
+- One week runtime for the full compression pipeline
+
+* Conclusion
+** Come and talk to us! \hfill www.softwareheritage.org
