Show HN: Parseable, an open observability datalake, handles 100M time-series/min

This looks super interesting. Question about the scale, I thought Thanos and some other Prometheus variants can handle about 100 million active time series. I would have expected your solution to scale to billions. Have you not pushed it past 100 million or am I maybe missing something.

We haven't yet tried pushing it to the scale of billions yet. The max that we've gone to is 150-180 million.

Definitely publish it! I’ll be following closely! 100M seems a bit too low to turn heads, but cool project nevertheless. Always exciting to see open source observability tools pop up!

I currently manage 50m active series and it’s brain dead easy using Mimir (which can also easily do 100-200m).

That being said, perhaps this Parseable project is much more efficient (RAM) in storing that 1b samples compared to Mimir (RAM). Once we add in object stores which cheapen the storage cost by orders of magnitude (by going from memory to disk), the comparison is even weaker. Mimir and Cortex/Thanos are quite happy to pull cold data from S3.

So I too expected to see “billions” as well.. hmm.

Yeah Mimir cleared a billion series years ago prior to several recent re-architectures that make it faster and more efficient to run.
