LLMs + REST APIs = powerful combos.

Here’s Claude Code querying a ~1BN row crypto dataset from QuestDB using plain SQL over HTTP. No SDKs, just curl.

Clean pattern for real-time insights with minimal setup. Screenshot below.

Kicking off a new series on order book analytics in SQL with #questdb: bid-ask spread, liquidity thresholds, imbalance, quote stuffing—directly over L2 snapshots. Follow along for real SQL examples this week.

We watched Interstellar. That movie is a trip!

Slow dashboards make us feel like the wave planet.

We like 'em live, like our fresh crypto dashboards.

Somewhere in a database... a lonely little row from 2017 still holds out for hope.

QuestDB’s TTL helps old data move on.

Listen, row, don't think of it as deletion... More like closure.

We just need some time for ourselves (and our more recent data).

This is your database when you don’t use materialized views to pre-compute aggregates.

Every dashboard refresh is like a hot iron to the foot.

Save your DB('s feet)! Materialize your views.

QuestDB now supports Oracle-style comments, so you can add helpful annotations…

Or sneak messages to your coworkers. 👀 ☕️

Getting from zero to ingesting, querying, and exporting data to Parquet with QuestDB in under 3 minutes. That’s what we showed live at STAC in London—no magic, just fast, SQL-native performance. #questdb #opensource #SQL #Parquet

This is what happens when you put together QuestDB and github.com/finos/perspe..., a data visualization tool designed for large and streaming data. Look at this cool blotter updating every 50ms with market data coming from QuestDB.

And that, kids, is how PHP made it into our codebase.

A user on PHP hit a QuestDB 8.2.2 issue. We gave an immediate workaround, then @jerrinot.bsky.social shipped a permanent fix 11 days later—with a new PHP test runner for coverage on par with Python or Rust. Community collaboration FTW!
Screenshot from slack, showing Jaromir saying: That's excellent news :tada: I included a PHP test runner in the fix. So from now on PHP PDO has the same test coverage as we have for Python, Rust or C#. This should prevent future regressions. Many thanks for your help: The report, reproducer and now the confirmation - it all helped greatly.

Did you know you can orchestrate and schedule your QuestDB data workflows using Airflow with the PostgresOperator or Dagster with a resource using psycopg?
Airflow web console view showing a graph with four tasks: Convert_to_parquet (postgresOperator), detach_partition (postgresOperator), upload_to_s3 (python_operator), delete_folder (python_operator) Dagster web UI view showing a graph with five operations: get_execution_date, convert_to_parquet, detach_partition, upload_files_to_s3, and delete_folder
