Overview
Spark estates grow by accretion. Jobs get copied, resource requests get inflated to make a deadline once and never revised, and pipelines outlive the reports they fed. AceMQ profiles the whole estate and returns a ranked list of what to fix, what to consolidate, and what to delete.
Challenge
Nobody has a complete picture of which jobs run, what they cost, and who consumes their output. Executor counts and memory settings were chosen defensively rather than measured. Several pipelines compute nearly the same aggregate from the same source. A meaningful fraction of jobs process small enough volumes that Spark's overhead exceeds the work, and would run faster as a single-node process.
Environment
Apache Spark on Kubernetes, EMR, Dataproc, or Databricks, with jobs orchestrated by Airflow or a native scheduler.
Approach
AceMQ collects event logs and scheduler history across the estate to build per-job runtime, resource allocation, and utilization profiles. Allocated resources are compared against peak observed usage to find over-provisioning, and output lineage is traced to find pipelines whose consumers no longer exist. Each finding carries a specific recommended action rather than a general observation.
Solution
- 1Estate-wide job inventory with runtime, allocated resources, peak utilization, and cost per run
- 2Over-provisioning analysis comparing requested executor memory and cores against measured peak usage
- 3Duplicate and near-duplicate pipeline detection through source and output lineage
- 4Identification of small-volume jobs where Spark overhead exceeds the work and a single-node engine is faster and cheaper
- 5Orphaned pipeline detection where downstream consumers no longer read the output
- 6Prioritized remediation backlog ordered by cost saved against engineering effort required
Outcome
Customers get a concrete, ordered backlog rather than a general efficiency report. Most estates contain enough over-provisioned and orphaned work to reduce compute spend substantially before any job is rewritten.
