It is in the sense that it's a purpose built time series database. Once upon a time it was definitely among the best too, but IMO their sales and tech and everything strategies have been just massive clusterfucks. They also have the best metrics agent, by far.

They deleted customer data permanently in their hosted version after sending two emails to billing addresses. Their marketing and product naming also sucks:

InfluxDB InfluxDB Cloud Serverless InfluxDB Cloud Dedicated InfluxDB Clustered
