TimescaleDB: Turn PostgreSQL into a Time-Series Engine with One Extension (Sponsored)

Problem

In standard PostgreSQL, all rows live in one table. As time-series data grows into the millions, queries cannot skip irrelevant data, so even recent lookups scan far more than needed.

Solution

TimescaleDB solves this with hypertables, which automatically partition data into time-based chunks.

Queries only touch the relevant chunks, leaving the rest untouched.

Other capabilities:

• Shrink storage by up to 95% with columnar compression that stays fully queryable
• Faster queries with continuous aggregates that refresh only new data
• Built-in retention policies to automatically remove old data

Guidance: One Function for Clean LLM Labels

Problem

Classification tasks with LLMs can get messy. Instead of a clean label, you might get “Option A”, “The answer is A”, or a full explanation.

Cleaning this up requires extra parsing, retries, and validation that can make your system fragile.

Solution

With Guidance, the select() function constrains the model to return exactly one option from your list.

Key benefits:

• Guarantees output matches one of your predefined options
• Eliminate parsing code and regex patterns
• Works with any list of valid choices
