Databricks is the right platform for Spark training, notebooks, Unity Catalog governance, and large-scale ETL. Databricks SQL was designed for interactive BI — not for sub-second customer-facing analytics or the concurrency that AI agent workloads demand. PhoenixAI handles the serving layer; Databricks handles everything else.

When to add PhoenixAI

Three signs Databricks SQL needs a serving layer.

Customer-facing queries stall under concurrent load

Databricks SQL is built for interactive BI — a few analysts querying at once. Customer-facing workloads need 10,000+ QPS at sub-second latency sustained over time. PhoenixAI is purpose-built for that access pattern, on the same Delta Lake data, without moving it.

AI agents need data fresher than Delta sync delivers

DeltaStreamer and Auto Loader batch-sync data into Delta Lake. Agents working on customer behavior or transaction data see what the last sync pushed. PhoenixAI ingests streaming data directly and serves it at sub-10 second freshness — without disrupting your Delta tables.

SQL warehouses are an expensive way to serve reads

SQL warehouses start cold, spin up slowly, and are priced for compute-heavy jobs — not always-on serving workloads. PhoenixAI delivers consistent sub-second latency on a serving-optimized architecture, at lower cost than running SQL warehouses hot 24/7.

What each system does best

Workload	PhoenixAI	Databricks
Customer-facing analytics	Sub-second, 10K+ QPS, multi-tenant	SQL warehouses queue under real user traffic
AI agent serving queries	Built for high-concurrency, unpredictable shapes	Not optimized for agent-scale concurrency
Real-time data freshness	Sub-10s from streaming sources	Delta sync is batch-based; minutes to hours
Spark ML training & notebooks	Not applicable	Industry-leading
Unity Catalog governance	Works with Unity Catalog	Full governance, lineage, access control
Large-scale ETL & data prep	Not the focus	Core Databricks strength
Delta Lake federation	Native Delta Lake reads, no copy	Source of truth
Always-on serving cost	Optimized for sustained serving workloads	SQL warehouses are expensive to keep warm 24/7
Deployment	BYOC: your AWS, GCP, or Azure account	Vendor-managed cloud

Teams running both.

Conductor

Greenfield agentic AI deployment

<2 months

idea to production

Built a new agentic AI application on a Hudi + S3 lakehouse. PhoenixAI served as the real-time query layer. Sub-second latency on 240 million rows. Greenfield to production in under two months.

Herdwatch

Replaced Athena on Iceberg lakehouse

700ms–1.5s

from 2–5 minutes on Athena

Query engine swapped on existing Iceberg tables. No data movement. Same Unity Catalog. Latency dropped from minutes to under 1.5 seconds. Databricks retained for training and ETL.

SmartNews

Consolidated Trino + ClickHouse

3.6×

faster than Trino on ad-hoc

Replaced two serving engines with PhoenixAI as the single analytical layer. 3.6× faster than Trino on ad-hoc queries. Spark and notebook workloads remained on the data platform unchanged.

What stays on Databricks

PhoenixAI is not a Databricks replacement. Databricks has deep capabilities PhoenixAI does not target. The following remain on Databricks and are not in scope for PhoenixAI.

Spark ML training & notebooks Unity Catalog governance & lineage Delta Lake as source of truth Large-scale ETL & data prep Databricks AI / GenAI features Mosaic AI training Databricks Marketplace

Add a real-time serving layer to your Databricks stack.

We’ll show you what sub-second latency looks like on your Delta Lake tables — no data movement required.
