The SQLite VLDB'22 paper provides a detailed overview of SQLite architecture. I appreciate the authors' effort in analyzing the performance comparison with DuckDB. They honestly reported OLAP use cases where DuckDB is significantly faster and measured one level deeper.

Speaking on panel @VLDB at 10:45
My take: we need to rethink relational tools for analysis, for instance, estimating typical property price from rich data.
The challenge is specifying the formula and not executing a query

I had missed that ByteDance had a 2022 VLDB paper on their HTAP database, which combines an Aurora-like shared storage system with Apache Flink to create a shared-storage separate-engine HTAP system. The "Related Work" section is a good HTAP survey too.
