QuestDB Overview

What is QuestDB?

QuestDB is the fastest growing open-source time-series database offering blazingly fast, high throughput ingestion and dynamic, low-latency SQL queries. We achieve high performance via a column-oriented storage model, parallelized vector execution, SIMD instructions, and low-latency techniques. In addition, QuestDB is hardware efficient, with quick setup and operational efficiency. QuestDB implements ANSI SQL with native time-series SQL extensions. These SQL extensions make it simple to analyze, filter and downsample data, or to correlate data from multiple sources using relational and time-series joins.

(Original )Information
What do you like best about QuestDB?

At my organization, we needed to build a real time analytics system for OTT streams and for this we needed a solid Time Series Database. Initally we were using elastic search but once we needed to scale up we consistently faced latency issues. So we needed a TimeSeries database which could handled load of billions rows every day. We decided to give Timescale DB a try and there also we faced multiple issues regarding latency. Then we discovered QuestDB and it was a game changer for us. After initial analysis we found that QuestDB is more performant than Timescale and Elasticsearch so we decided to give it a chance. Our use case was to ingest 3 million rows per second and QuestDB was able to handle this load easily. We have been Using QuestDB since 2022 now and we never looked back for another database. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

We have been using QuestDB for last two years and haven't found any issues so far. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

We are an OTT company so we need to collect cdn logs and analyze them to find most streamed contents. These logs come according to timestamp so we needed a time series database. Intially we were ingesting 5k rows per second and Elasticsearch was sufficient for this use case but as scale grew we needed a more performant database. For this we done analysis on TimeScale and QuestDB. With QuestDB we were able to ingest 3 Million rows per second with minimal delay. With timescale while we were facing latency on simple group by queries (upto 30 seconds), Quest DB was able to perform same queries under 500 milliseconds. So to summarize we needed a both read and write performant DB and QuestDB was able to achieve both. Review collected by and hosted on G2.com.

What do you like best about QuestDB?

The simple deployment and upgrade processes. The ability to manage dynamic data with varying variables/sensors per row. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

The lack of a compressed format for exporting or for returning large result sets. Given the recent developments with added parquet support I guess this situation might change soon. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

Persisting and analysing/querying large sets of sensor data from various PLC machines.

At a client we have a setup with various PLC machines with different sensors attached. We sample data of some 100-300 variables at rates of 500Hz to 1kHz.

Initially we tried other solutions with bad performance due to the varying datasets. Other solutions struggled with performance when the datamodel got updated (added or removed sensors).

With QuestDB we managed to easily deploy a setup where ingesting this type of data was no problem. We went with small edge-deployed servers dealing with single PLC and a two larger QuestDB instances where one was used to aggregate data for all PLC's to facilitate any near-realtime queries of status of all PLC's and the other larger instance was used to persist data-sets that was classified as valuable to keep for long term analysis.

Having the http/rest-api allowing ingestion and queries simplifies integration with other systems of ours without the need to link to specific database libraries.

The built-in UI that houses query capabilities among others allow us to run quick tests and concepts and in recent releases this also hints at bad server configurations and how to fix some bad server configuration to get the best QuestDB experience.

As a developer I have really enjoyed the open and welcoming attitude by the QuestDB developers. They have actively listened and implemented a lot of end-user suggestions. Review collected by and hosted on G2.com.

What do you like best about QuestDB?

QuestDB fits our needs. We handle and analyze large datasets of cell growth data with measurements over time, often as CSV files. This time-series-based database fits our use case very well. By importing it into an SQL database, developers can quickly implement a convenient and known way to get statistics from selections made in the front end.

We look forward to integrating streaming data from measurements into the database at a later point, but we are not there yet. We know that it is possible in this setup.

Also, the Slack channel is friendly, and the direct contact with developers is excellent. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

I have nothing big to complain about, but if I have to complain about something, there was one non-backwards-compatible upgrade. It was fixed on our side but unexpected from the usually very stable product development. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

As our data is a time series, it fits our needs like a hand in a glove. Also, the automatic CSV import made our development time significantly shorter, saving the company a lot of money. Review collected by and hosted on G2.com.

What do you like best about QuestDB?

Byond QuestDB being *incredibly fast*, it's also a joy to use. And more importantly, it's not a pain to use. Other DBs require more ongoing maintenance, troubleshooting, etc. QuestDB truly is a "set it & forget it", trustworthy DB that shines in production workloads.

The inbuilt SQL extensions and curated dialect make writing QuestDB SQL fast, fun, and powerful. The inbult REST support, in addition to the InfluxDB Line Protocol & PG Wire connection methods allow the user to select the best tool for the job.

Being open source, the deployment flexibility is fantastic. The QuestDB team regularly meets with us to ensure we're satisfied, and they regularly ship impactful features.

QuestDB is my definitive go-to for all timeseries needs! Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

The QuestDB web console UI is helpful for adhoc exploration, but does not currently have a means of organizing / saving queries, so it gets messy fast. Additionally, some BI solutions (like PowerBI) or downstream applications can't connect to QuestDB's flavor of PG Wire, so we've had to go through the REST API in these cases. Fortunately, the QuestDB team is on it and anticipates delivering a fix to that soon. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

We've tried Timescale, which simply takes just too much maintenance & configuration to optimize performance and stay agile. QuestDB requires almost no ongoing configuration because it ships incredibly fast by default. QuestDB eliminates the friction in storing & querying timeseries data.

What do you like best about QuestDB?

I had invested a lot of time prototyping a project with another time-series database and was finding a lot of pain points. I decided to give QuestDB a go, and the transition process was really easy and most of the issues I had with the other DB simply went away. Additionally, I gained valuable time when my application starts and has to read current state from the DB... QuestDB delivered my data in half the time the other DB did. I also like the SQL syntax - it's just one less new thing I need to pick up when starting with QuestDB. The free/open source version is great for my purposes. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

Documentation is pretty good, but I would like to see some more around best practices, particularly with how to design a schema that is optimal for my needs. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

I need to keep track of the current state of about one million data points that change over time. QuestDB had made this simple to do. Review collected by and hosted on G2.com.

What do you like best about QuestDB?

So, we had this real-time analytics use case and we're searching all across for the right time series database with a lightening performance. We landed up to an ad on Google mentioning QuestDB as a better alternative.

We went through their deep dive blog comparing both the DB archs and we understood the gains are on the upside.

Upon testing, it proved to be an excellent choice. Started using it extensively and found it to deliver on its promises.

Another thing we liked is their open Slack community always ready to help with any issues we might have. A big PLUS in my eyes. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

Since this is a newer offering compared to the other DBs, it has its pain points. Like random "table suspended" issues with health checks not updating properly requiring manual restarts, and other minor hiccups.

They do take feedback consistently improving their DB and clients like recently they upgraded from TCP to TCP over HTTP on all their clients to rectify our above mentioned issue.

Overall, I would say although it's a newer alternative, it's evolving rapidly, and I would suggest anyone looking for a time series DB, do give this a try. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

It's helping us ingest real-time analytics events from our users. Review collected by and hosted on G2.com.

What do you like best about QuestDB?

We recently evaluated several options for storing high frequency historical market data. Our initial choice was TimescaleDB because we use Postgres however it was simply not fast enough for our use case. Eventually we found QuestDB and though it was missing a few 'nice to have' features, it more than delivered on speed and ease of use.

Their support team has also been great with helping us out whenever we need it, certainly one of the best support experiences from any of the services we have enterprise contracts with. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

It's not quite as feature rich as other options, specifically we are very much looking forward to materialised view support! Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

Storing many thousands of records per second and powering an api that is used to analyse this data via both adhoc queries and a frontend charting app that is hooked up to quest via an intermediate api service that handles auth and caching. Review collected by and hosted on G2.com.

What do you like best about QuestDB?

Our project have been using Solr as a statistics data storage for years. It was not a right decision because Solr is not good solution for realtime data processing. The best approach in our case is a time series database. Using such DB in embedded mode was another important requirement. There are a lot of competitors in this market, but QuestDB was the only one who offers embedded mode. So we gave a chance to QuestDB and never regreted.

It`s great to see the rapid evolution of QuestDB. The developers team constantly introduces new features, improvements and bug fixes.

Also want to note an excellent support. The ability to ask a question directly to developers and get answer in Slack channel is a really cool. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

Actually the embedded mode chapter looks to be the smallest part of documentation. It would be nice to add some best practice advices and code examples. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

The biggest problem to solve was real time processing and storing statistical data our application collect from various sources. These data should be used for building reports and charts.

QuestDB perfectly fits our needs. Review collected by and hosted on G2.com.

What do you like best about QuestDB?

- Very responsive and co-operative support from developers/community.

- Helpful features already up and running from various versions, many more to come in the future!

- Clear roadmap that clarifies what we can expect and when.

- Loads of tools to intergrate with. Review collected by and hosted on G2.com.

What do you dislike about QuestDB?

- Current data storage feature consumes more storage, however the upcoming parquet file format shall reduce it. Review collected by and hosted on G2.com.

What problems is QuestDB solving and how is that benefiting you?

- Currently, we are using QuestDB to visualize our time-series customer data with Grafana.

- Thanks to the developers, they released an official version supporting Grafana upon the réquest. Also, using ZFS compression enabled for additional data compression.

- We had the old customer data in the legacy MySQL formats and QuestDB simplifies every work, especially ingestion speed is very helpful.

- I, as a developer, am currently looking forward to the parquet file version that further simplifies our development process. Review collected by and hosted on G2.com.
