Emergency Incident Response
Production pipelines down, jobs failing cluster-wide, or a workspace that won't provision. A senior engineer joins a live bridge within 15 minutes with direct access to diagnose.
Databricks Support
Last reviewed by Scott Sternloff
AceMQ supports Databricks in production across AWS, Azure, and GCP — job cluster cold starts, Delta small-file compaction, skewed joins, and Unity Catalog migrations off the legacy Hive metastore. Every ticket reaches a named senior engineer who already knows your workspace.

Incident Triage
These are real symptoms from real Databricks production environments — and the first thing our engineers check when one comes in.
| Symptom you're seeing | What we check first | Typical resolution |
|---|---|---|
| Job clusters spend most of their billed time on cold start | Autoscaling min/max worker settings against actual job runtime. A min_workers of 0 forces a full cluster provision on every scheduled run — often the majority of the DBU bill for short jobs. | 1–2 hours |
| Delta table writes slowing down, thousands of tiny files piling up | Average file size via DESCRIBE DETAIL and OPTIMIZE history. High-frequency streaming writes without auto-compaction or a scheduled OPTIMIZE job are the standard cause. | 1–3 hours |
| Driver returns 'not responsive' or crashes with OOM | Notebook and job code for collect() or toPandas() calls pulling a full dataset to the driver node, plus broadcast join thresholds against actual table size. | Under 2 hours |
| One executor runs 10x longer than every other task in the stage | Spark UI stage detail for partition size skew on the join key. Salting the key or enabling adaptive query execution's skew join handling is the usual fix. | 1–3 hours |
| Unity Catalog permission errors after a Hive metastore migration | External location grants, metastore assignment, and which tables were never registered into Unity Catalog — lineage gaps trace back to this almost every time. | 2–4 hours |
| DBU spend blows past budget with no workload change | Cluster event logs for all-purpose clusters left running versus job clusters, and auto-termination timeout settings. Idle all-purpose clusters are the most common line item. | Same day |
| VACUUM removes files a running time-travel query still needs | Retention interval configuration against in-flight time-travel queries and any concurrent OPTIMIZE jobs touching the same table. | Under 2 hours |
| Photon isn't engaging on a workload that should qualify | Cluster runtime version and whether the workload's operators are Photon-supported — a single UDF in the query plan disqualifies the whole stage from Photon acceleration. | 1–2 hours |
Resolution times reflect typical Databricks engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.
What's Included
No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.
Production pipelines down, jobs failing cluster-wide, or a workspace that won't provision. A senior engineer joins a live bridge within 15 minutes with direct access to diagnose.
Every P1 closes with a written RCA: what failed, why, the fix applied, and the specific configuration change that prevents recurrence.
Cluster sizing, autoscaling policy, Photon eligibility, and Delta table layout tuned against your actual job runtime and DBU budget — not generic best practices.
Cluster policy review, job-vs-all-purpose cluster audits, and quarterly DBU spend analysis so runaway clusters get caught before the invoice does.
Proactive alerts for security issues affecting your exact Databricks Runtime version, with tested upgrade paths that account for job compatibility.
Hive metastore to Unity Catalog migration planning, workspace-to-workspace moves, and lineage remediation for tables that fell through the cracks.
Why AceMQ
The same senior engineers stay on your account. They know your cluster policies, your Delta table layout, and your job schedules — so a P1 starts with diagnosis, not you re-explaining your workspace.
You reach a senior Databricks engineer directly by phone, email, or Slack. No help desk collecting information, no escalation approval process between you and someone who can fix it.
We support Databricks, Snowflake, and Starburst as a connected stack, not in isolation — which matters when the actual problem is where data lives, not which engine is running the query.
Quarterly cluster policy and DBU spend reviews are standard, not an upsell. Most Databricks cost overruns are idle all-purpose clusters nobody is watching, and we watch.
Engineers across 26+ countries and every time zone. Your 3am pipeline failure is someone's mid-afternoon — no overnight skeleton crew.
Databricks problems are often cloud IAM, network, or storage problems wearing a Spark stack trace. We diagnose across the cloud provider, the JVM, and the lakehouse layer.
Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.
Escalation Path
Every tier reaches a senior Databricks engineer. There is no tier-1 triage layer to get through.
P1 escalation path
A replay of one P1, from the first page to the written root-cause analysis
15-minute P1 response, 24/7.
A response time, not a resolution time.
P1 opened, on-call engineer paged
Phone, email or Slack reaches the on-call senior engineer directly, whether the incident is in RabbitMQ, Kafka, Redis, PostgreSQL or Kubernetes. No web form, no tier-1 queue.
Senior engineer on your bridge
A senior engineer who already knows your environment joins a live bridge, so nobody has to re-explain your topology.
Specialists across the stack join
When an incident crosses components, the engineers who know each one join. For RabbitMQ, the path runs to the core team.
Written root-cause analysis
Root cause, the fix applied and the prevention steps, delivered after every P1.
Pricing
AceMQ Databricks support contracts typically run $24,000–72,000 a year, depending on SLA level, scope (number of clusters or nodes, and environments) and deployment (self-managed, cloud-managed or Kubernetes).
| What moves the price | How it changes the contract |
|---|---|
| SLA level | Business-hours cover costs less than 24/7 cover with a 15-minute emergency response. |
| Scope | More clusters or nodes, and more environments, make a larger contract. |
| Deployment | Self-managed, cloud-managed and Kubernetes estates need different amounts of hands-on work. |
Covering several technologies under one contract, for example RabbitMQ, Kafka and Redis, earns an aggressive discount.
Support In Practice
Databricks support and remediation work from AceMQ. Each card links to the full write-up: the workspace, what AceMQ diagnosed or changed, and the result.
Global Payments Processor
Right-sizing Databricks compute by moving scheduled work off all-purpose clusters and tightening autoscaling, instance selection, and idle timeouts.
Digital Retail Platform
Fixing Delta tables where streaming writes and over-partitioning have produced millions of tiny files, stalling reads and vacuum operations.
Insurance Services Group
Named-engineer support for production Databricks job failures — driver OOM, spot reclamation, library conflicts, and workflow retry storms.
Media Streaming Provider
Profiling a Spark estate to find over-provisioned jobs, redundant pipelines, and workloads better served by something other than Spark.
Healthcare Analytics Provider
Migrating off the legacy Hive metastore to Unity Catalog with external location mapping, table upgrades, and a grant model that survives audit.
Support options
AceMQ offers Databricks support in four tiers, each handing more of the day-to-day work to AceMQ: 24/7 support and incident management for jobs and pipelines your team runs, proactive monitoring that finds cost and Delta table problems first, managed Databricks inside your own cloud account, and fully managed Databricks run on your behalf from an AceMQ-managed cloud account and infrastructure, with the pipeline tooling around it. All three clouds and the Databricks Runtime LTS releases are covered.
You run it, we back you up
Best for: Data engineering teams that run Databricks themselves and need senior escalation cover for production pipelines.
You run it, we watch it with you
Best for: Teams that want the idle all-purpose cluster or the small-file pile-up found in a review, not on the invoice.
We run it in your cloud or data centre
Best for: Regulated estates that must keep data and compute inside their own cloud boundary.
We host it and run it, as a service
Best for: Teams that want Databricks and the platform around it run for them, without building a pipeline operations team.

Every Tier can start as an ad hoc engagement or an annual partnership, and you can move up or down a Tier as your team changes.
One partner for Databricks
Support is one part of what AceMQ does for Databricks. The same engineers deliver consulting, health checks, migrations and end-of-life cover, and support the systems that usually run next to it.
Our Databricks support covers 24/7 emergency incident response with a 15-minute SLA, root cause analysis on every P1, performance and cluster-sizing tuning, DBU cost governance, CVE and patch advisory, and migration or Unity Catalog support. Every ticket is handled by a named senior engineer assigned to your account, with no tier-1 triage layer.
Yes — cost governance is one of the most common reasons enterprises bring us in. We audit cluster policies, job-vs-all-purpose cluster usage, autoscaling configuration, and auto-termination settings, then run quarterly reviews so idle clusters and cold-start waste get caught before the next invoice, not after.
Yes. We support Databricks on all three cloud providers, including PrivateLink and VNet/VPC peering deployments. The core engine issues — cluster sizing, Delta table layout, skewed joins — are consistent across clouds; the cloud-specific issues are IAM, networking, and billing integration, which we also cover.
Yes. We plan and execute Hive metastore to Unity Catalog migrations, including external location grant mapping, lineage remediation for tables that weren't cleanly registered, and a validation pass to confirm nothing was silently dropped during the move.
P1 emergencies — pipelines down, cluster-wide job failures, a workspace that won't provision — get a 15-minute first response with a senior engineer joining a live bridge. P2 critical issues are 1 hour, P3 high-priority 4 hours, and P4 standard questions next business day. These are contractual targets.
Yes, and this is where a lot of value shows up. Many enterprises run Databricks, Snowflake, and Starburst together as a lakehouse-plus-warehouse stack. We support all three, which means we can diagnose issues that live at the boundary between them instead of pointing at 'the other vendor.'
Databricks sells Business, Production and Mission Critical support plans. On Production and Mission Critical, a Severity 1 case gets a first response within 1 hour, and a Mission Critical severity issue within 15 minutes with an escalation manager assigned. Those plans fix the platform. They do not tune your jobs, Delta tables or cluster policies, which is the layer AceMQ Databricks support covers, and we write the Databricks case with the diagnosis attached when the fault is theirs.
Yes. Each Databricks Runtime LTS release gets three years of support, so 14.3 LTS ends on 1 February 2027 and 15.4 LTS on 19 August 2027, and jobs pinned to those runtimes have to move. We inventory which clusters and jobs run each runtime from the system tables, test them against the target LTS, including Spark and library changes, and stage the rollout so a failing job rolls back instead of blocking a pipeline.
Yes. AceMQ works on Databricks in two ways: ad hoc engagements for a defined piece of work, such as a health check, an upgrade or an incident, or an annual partner engagement that covers 24/7 support, proactive reviews and named engineers. Many teams start ad hoc and move to an annual partnership once the first engagement is done.
Every AceMQ proposal is tailored to your requirements: your Databricks environment, the SLA you need, the hours of cover and the scope of work. Most contracts run $24,000–72,000 a year, depending on the SLA, the scope and how Databricks is deployed, with aggressive discounts when several technologies share one contract.
