  • Databases in 2025: A Year in Review
    QuestDB at least is gaining some popularity: https://questdb.com/ I was hoping to learn about some new potentially viable alternatives to InfluxDB, alas it seems I'll continue using it for now. - Source: Hacker News / 7 months ago
  • How to Forecast Air Temperatures with AI + IoT Sensor Data
    If your data lacks uniform time intervals between consecutive entries, QuestDB offers a solution by allowing you to sample your data. After that, MindsDB facilitates creating, training, and deploying your time-series models. - Source: dev.to / over 2 years ago
  • K3s Traefik Ingress - configured for your homelab!
    But of course, I want to run a QuestDB instance on my node, which uses two additional TCP ports for Influx Line Protocol (ILP) and Pgwire communication with the database. So how can I expose these extra ports on my node and route traffic to the QuestDB container running inside of k3s? - Source: dev.to / over 2 years ago
  • Annotations in Kubernetes Operator Design
    In this post, I will detail a way in which I recently used annotations while writing an operator for my company's product, QuestDB. Hopefully this will give you an idea of how you can incorporate annotations into your own operators to harness their full potential. - Source: dev.to / over 2 years ago
  • Is all data time-series data?
    QuestDB is an open source, high performance time series database. With its massive ingestion throughput speeds and cost effective operation, QuestDB reduces infrastructure costs and helps you overcome tricky ingestion bottlenecks. Thanks for reading! - Source: dev.to / over 2 years ago

  • How we've approached reliability & cost savings for our strapped SaaS
    We've come a long way from my first iteration where I ran speedtest-cli in a docker container that posted data to mysql all hosted on a single ec2 instance in AWS, with absolutely no fault tolerance or scaling. Now we host our stack in containers running in GKE, split into their own microservices, passing data between our services using pubsub, and using a bad ass new TimeSeries database QuestDB. Additionally, our... Source: over 3 years ago
  • Advice on dealing with massive options data
    This is a very good answer. Clickhouse does not preserve row order though - you may be better off with https://questdb.io/ as it's designed for basically exactly this, and is free. Not sure why Mizzlr says TDengine is limited in schema design... it's also designed for exactly this. Source: over 3 years ago
  • How to Build API with Go and QuestDB
    QuestDB is a relational column-oriented database designed for time series and event data. It uses SQL with extensions for time series to assist with real-time analytics. - Source: dev.to / almost 4 years ago
  • Timeseries Database for 100M timeseries
    Try in memory db called https://questdb.io is probably one of the fastest in market. Storage solution would have to implemented by you. Source: about 4 years ago

  • Ask HN: Data infrastructure for IoT data
    I'm writing docs for https://questdb.io/ which offers SQL-based analytics for time series. We have quite a few users already who use us for ML applications that rely on performance. Instead of writing an MQTT -> PostgreSQL bridge, you could use Telegraf to listen to MQTT topics and write data to QuestDB over InfluxDB line protocol when it meets certain criteria. One of our users shared the tooling they use in... - Source: Hacker News / almost 5 years ago
  • Using Telegraf and QuestDB to store metrics in a time series database
    Although Telegraf can collect an exceptional amount and variety of data, we need to store and visualize this information at some point. Considering that we collect the metrics over time, a convenient way to store time series data is using a time series database. We'll use QuestDB for ingestion and perform some basic visualization for this tutorial. - Source: dev.to / about 5 years ago
  • How do you store the stock market time-series data?
    I write the docs for QuestDB which is built for this, and we have users already using us for algotrading, so this might be interesting for you. From Python, the fastest inserts will be using InfluxDB line protocol. Source: about 5 years ago
  • What is the fastest way to communicate between a database and the program?
    I write documentation for QuestDB which I can recommend if latency is a priority for your project. You can use postgres wire using psychopg2 for a quick start. Some types of queries are optimized more than others, but it's likely you can get the performance you're looking for. Source: about 5 years ago
  • What database do you recommend for stats app with filtering
    For showing financial data over time, a time series database is a good choice. I write the docs for QuestDB which is used a lot for this. Also, I'm curious why SQL is definitely out of the question. Source: over 5 years ago
