Thanks, it does help! I understand SQLite might be better/ideal for OLTP (?) but would DuckDB also work for use cases where I query for specific records (e.g. based on primary key) or would I rather use SQLite for OLTP stuff and then read SQLite from DuckDB for analytical workloads?

Basically I'm wondering: if I go all in on DuckDB instead of SQLite would I notice? Do I have to keep anything in mind?

I know, probably difficult to answer without a concrete example of data, schema, queries and so on.

The SQL query features in the article seem really neat. Kudos @ shipping.

Good questions! You are correct that it depends. We do have indexes to help with point queries, but they are not going to be quite as fast as SQLite because DuckDB stores data in a columnar format. (Soon they will be persistent - see comments above!) That columnar format is really great for scanning many items, but not optimal for grabbing all of a single row.

With DuckDB, bulk inserts are your friend and are actually super fast.

Definitely let us know what you find! Just open up a discussion on Github if you'd like to share what you find out: https://github.com/duckdb/duckdb/discussions
