What do you like best about the product?

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.

What do you dislike about the product?

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.

What problems is the product 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.
