Do you store the block chain in a SQL database as well as neo4j? If so, what SQL database are you using? I've written a tool that stores the block chain in PostgreSQL but INSERTs are getting a bit slow due to indexes. Maybe we could share notes...

I am using SQLite (yeah) for blockchain data and the C++ LEMON library for in-memory graph operations. Every module is able to update incrementally.
