At Thumbtack we use InfluxDB to store monitoring metrics collected from all of our systems. It currently handles the ingestion of more than 200,000 data points per second and with our current retention policies this adds up to 7.5TB of data.
We prefer to operate on open-source software, one of the reasons we were drawn to InfluxDB. However, the open source core does not provide high availability features.
As we grew, rolled out new features, and collected more and more metrics (the amount of which has almost doubled over the past 12 months),
