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?
