InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Similar to fsync, these are designed to ensure data integrity, but in a test setup, they don't matter. You can read more about these in the Postgres doc on non-durability. and explore some benchmarks from Gitlab here. Interestingly, CircleCI's old Postgres images had these features disabled by default, but the newer ones don't seem to.
To fix this, we upgraded to a newer version of the CircleCI orb that allowed us to omit the branch name from the cache key. This immediately fixed things. Now both initial builds and subsequent builds were equally as fast. And we now save on storage costs, since we now share the cache across branches. In the three months preceding this, we had used 500–900 GB of storage on this service each month; in the two months since, we've used 500GB in total.
