The fact that many companies (FB, Uber, Google, Netflix, SO) roll their own TSDBs for metrics collection suggests that there is a real need. Or maybe there is not. It could a way to make boring system monitoring jobs fun and fancy again.

Perhaps these companies have such varied requirements that none of the existing TSDB systems fully support? We built our own custom time series db, along with a suite of tools for accessing, slicing, plotting, etc bc (at the time, at least) there was no support for bitpacking data, and storing/calculating certain spatial data operations.

My first job was in 2005 writing a TSDB abstraction over sql server used for BI with defense.

we merged ~30Gb of data per night in about 8hrs on a 32core machine which was severly limited by a platter SAN. We would get about 1 disk failure /6months.

So do u need an actual TSDB? Or are other companies doing what we did?
