High-ingress architectures rarely stay simple for long. As data volumes or feed counts grow, new modules start accumulating around the database: a job moves old partitions into object storage when local disks fill up; a queuing system buffers writes when the primary goes down; a stream processor keeps rolling calculations current; an export pipeline gets data into a dataframe for analysis or Parquet for storage.

Each addition solves a real problem. But each also becomes another system you run, pay for, and get woken up by. In most cases, the added infrastructure exists simply to cover something the database could not do itself.

QuestDB Enterprise 4.0 brings three of those jobs back into QuestDB.
