What to do about SQLITE_BUSY errors despite setting a timeout - Bert Hubert's writings

Wed, 19 Feb 2025 02:01:34 +0000

The tl;dr on this, to prevent SQLITE_BUSY errors even when setting a timeout, don’t ever upgrade transactions to read-write. If you know you are going to write in a transaction, use ‘BEGIN IMMEDIATE’, or start off with the write. But do read on for why this is so, and how other databases struggle with this problem as well.

Turning Your Root URL Into a DuckDB Remote Database | Drew Breunig

Mon, 02 Dec 2024 21:42:22 +0000

On the Overture Slack, Jake Wasserman shared a cool trick where you can connect to a remote DuckDB database using the ATTACH statement, using an HTTP or S3 URL. Jake’s demo was especially cool because he created a DB containing only views referencing an Overture parquet on S3, so the hosted database file was only a couple hundred kilobytes.

Writing Composable SQL using Knex and Pipelines

Fri, 29 Nov 2024 03:25:56 +0000

We have used a query builder to programmatically build SQL queries, and by using higher-order functions (functions that take other functions as arguments) and pipelines, we have: Eliminated the need to pass the query object explicitly. Made it easier to add, remove, or rearrange query modifiers without disrupting the overall structure. Improved maintainability and simplified testing since each query modifier function is a self-contained unit that can be reused across various queries and scenarios.

SQLite Index Visualization: Structure

Sat, 16 Nov 2024 04:16:30 +0000

After learning about indexes, I understood their basic structure, but I wanted to dig deeper — to explore the data structure, understand the algorithm, and learn how the index data is stored on disk. The theory and actual implementation can differ, so I decided to explore this topic further.

Vector Databases Are the Wrong Abstraction

Tue, 29 Oct 2024 23:29:14 +0000

A more effective abstraction is conceptualizing vector embeddings not as independent tables or data types but as a specialized index on the embedded data. This is not to say that vector embeddings are literally indexes in the traditional sense, like those in PostgreSQL or MySQL, which retrieve entire data rows from indexed tables. Instead, vector embeddings function as an indexing mechanism that retrieves the most relevant parts of the data based on its embeddings.

Cron-based backup - Litestream

Sun, 27 Oct 2024 22:19:44 +0000

Sometimes Litestream can be overkill for projects with a small database that do not have high durability requirements. In these cases, it may be more appropriate to simply back up your database daily or hourly. This approach can also be used in conjunction with Litestream as a fallback. You can never have too many backups!
