ActorDB. Distributed SQL database written in Erlang built on top of SQLite (on top of LMDB), adding replication using the raft consensus algorithm (so sharded with no single-points of failure) and a MySQL protocol interface. Interesting combination of technologies. # 24th June 2018, 9:48 pm
Query Parquet files in SQLite. Colin Dellow built a SQLite virtual table extension that lets you query Parquet files directly using SQL. Parquet is interesting because it’s a columnar format that dramatically reduces the space needed to store tables with lots of duplicate column data—most CSV files, for example. Colin reports being able to shrink a 1291 MB CSV file from the Canadian census to an equivalent Parquet file weighing just 42MB (3% of the original)—then running a complex query against the data in just 60ms. I’d love to see someone get this extension working with Datasette. # 24th June 2018, 7:44 pm
