The journey to today's version of QuestDB began with the original prototype in 2013, and we've described what happened since in a post published during our HN launch last year. In the early stages of the project, we were inspired by vector-based append-only systems like kdb+ because of the advantages of speed and the simple code path this model brings. We also required that row timestamps were stored in ascending order, resulting in fast time series queries without an expensive index.
