Apache NiFi Support

24/7 Apache NiFi Support with a 15-Minute Emergency SLA

AceMQ supports Apache NiFi flows in production — content and FlowFile repositories filling disk from unbounded backpressure, cluster nodes dropping out from the coordinator under load, and provenance repositories growing until they take down a node. Every ticket reaches a named senior engineer who already knows your flow topology.

Escalation Path

Your first hour of a Apache NiFi outage

Most vendors publish an SLA number. This is what actually happens, minute by minute, when you page a senior AceMQ engineer.

T+0

You page us

Phone, email, or Slack — any channel reaches the on-call senior engineer directly. No web form, no tier-1 queue.

T+15

Named engineer live

A senior engineer who already knows your environment joins a live bridge. Zero cold-start, no re-explaining your topology.

T+30

Root cause isolated

Direct broker access, log and metric review, and a working hypothesis with a rollback plan before we touch anything.

Post

Written RCA

Documented root cause, the fix applied, and the prevention steps — delivered after every P1, not just when asked.

Response Times

SLA tiers, contractually guaranteed

Every tier reaches a senior Apache NiFi engineer. There is no tier-1 triage layer to get through.

P1 — Emergency
15 min

Production down, messages not flowing, cluster or broker failure

P2 — Critical
1 hour

Severe degradation, rising error rates, approaching capacity limits

P3 — High
4 hours

Performance issues, configuration problems, non-critical failures

P4 — Standard
Next day

Questions, guidance, best practices, non-urgent improvements

Incident Triage

Apache NiFi problems we fix every week

These are real symptoms from real Apache NiFi production environments — and the first thing our engineers check when one comes in.

Disk fills up on a NiFi node and the flow grinds to a halt
What we check firstWhich connection queue is backpressured and why. A downstream processor that's slow, failing, or stopped — with no back-pressure object or size threshold set on the queue feeding it — lets the FlowFile and content repositories grow unbounded.
Typical resolutionUnder 1 hour
A node disconnects from the cluster under load, keeps flapping
What we check firstCluster coordinator heartbeat timeouts and network latency between nodes. Under sustained high throughput, heartbeat intervals set too aggressively for actual network conditions cause healthy nodes to be marked disconnected repeatedly.
Typical resolution1–3 hours
A processor shows 'running' but nothing is actually processing
What we check firstThread pool exhaustion — whether the processor's concurrent task setting has consumed all available threads in the timer-driven or event-driven pool, starving it and every other processor sharing that pool.
Typical resolution1–2 hours
Provenance repository disk usage grows until a node goes unresponsive
What we check firstProvenance retention settings (max storage size and time) against actual event volume. High-throughput flows with default provenance retention will fill a dedicated provenance volume faster than most teams expect.
Typical resolutionUnder 2 hours
Site-to-site or cluster communication suddenly breaks
What we check firstSSL/TLS certificate expiry on the nodes involved. Certificate expiry is the single most common cause of a previously-working cluster or site-to-site connection failing with no configuration change made.
Typical resolutionUnder 1 hour
One node's flow behaves differently from the rest of the cluster
What we check firstflow.xml.gz version and checksum across all nodes. A manual change made directly on one node instead of through the cluster-managed flow definition causes silent drift that only surfaces as inconsistent processing.
Typical resolution1–2 hours
High-volume flow causes GC pauses and processing stalls
What we check firstJVM heap allocation against FlowFile attribute size and volume. NiFi keeps FlowFile attributes in heap, and flows with large or numerous attributes per FlowFile need heap sized well beyond the shipped defaults.
Typical resolution2–4 hours
Custom processor broke migrating from NiFi 1.x to 2.x
What we check firstProcessor API compatibility and Python vs. Java processor framework changes introduced in 2.x. The 1.x-to-2.x jump changes enough of the extension model that most custom Java processors need real rework, not a recompile.
Typical resolution2–4 hours

Resolution times reflect typical Apache NiFi engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.

What's Included

Everything in your Apache NiFi support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

Emergency Incident Response

A node goes down, disk fills, or a critical flow stops processing. A senior engineer joins a live bridge within 15 minutes with direct cluster access to diagnose — not a ticket acknowledgement.

Root Cause Analysis

Every P1 closes with a written RCA: what failed, why, the fix applied, and the specific backpressure, queue, or config change that prevents recurrence.

Flow & JVM Performance Tuning

Backpressure thresholds, thread pool sizing, provenance retention, and JVM heap allocation tuned against your actual FlowFile volume and attribute size.

Certificate & Cluster Health Advisory

Proactive tracking of TLS certificate expiry across nodes and site-to-site connections, plus cluster coordinator heartbeat tuning to stop node flapping before it starts.

Disk & Capacity Reviews

Quarterly reviews of repository disk growth trends — content, FlowFile, and provenance — so you size storage ahead of throughput growth instead of reacting to a full disk.

Migration & Custom Processor Support

NiFi 1.x to 2.x migration planning, custom processor rework for the updated extension model, and flow architecture review for teams scaling past a few hundred processors.

Anywhere You Run It

We support Apache NiFi wherever it's deployed

Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.

Why AceMQ

What you get that you don't get elsewhere

Named Engineers, Zero Cold Start

The same senior engineers stay on your account. They know your flow topology, your processor groups, and which queues are fragile — so a P1 starts with diagnosis, not twenty minutes of explaining your environment.

No Tier-1 Triage Layer

You reach a senior NiFi engineer directly by phone, email, or Slack. No help desk collecting information to pass along, no escalation approval process standing between you and someone who can fix it.

We Read the Flow, Not Just the Logs

Most NiFi incidents trace back to a specific backpressure setting or processor configuration buried in the flow definition. We open the canvas and trace the actual data path, not just the error log.

Genuine Follow-the-Sun Coverage

Engineers across 26+ countries and every time zone. Your 3am disk-full alert is someone's mid-afternoon — no overnight skeleton crew, no waiting for a region to wake up.

Proactive, Not Just Reactive

Quarterly health checks on repository growth and certificate expiry, plus shared intelligence across our support base. When a version-specific bug surfaces on one customer's cluster, every affected customer hears about it before it reaches their production.

Full-Stack, Not Just the Flow Canvas

NiFi problems are frequently disk, JVM, network, or certificate problems wearing a stalled-flow symptom. We diagnose across the whole stack because that's where root causes usually live.
