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.** Full post at [QuestDB Enterprise 4.0: cold storage, QWP, and restart-free failover | QuestDB](https://questdb.com/blog/questdb-enterprise-4-0-release/) ---
