TigerData vs Databricks (Iceberg lakehouse): best pattern for real-time + historical telemetry queries?

Most teams hitting telemetry scale are deciding between two patterns: keep everything in a Postgres-native system that can handle live + historical queries, or split operational workloads and analytics across a Databricks + Iceberg lakehouse. The right answer comes down to latency expectations, operational tolerance for “brittle glue,” and how much you want Postgres to stay at the center of your architecture.

Quick Answer: TigerData is best when you need sub‑second, SQL‑native queries across hot and warm telemetry (seconds to months) without stitching together Kafka, Flink, and lakehouse jobs. Databricks + Iceberg shines when your priority is large‑scale offline analytics and ML on multi‑petabyte data, and you’re okay with higher latency and more moving parts for real-time paths.

The Quick Overview

What It Is: A comparison between a Postgres‑native telemetry platform (TigerData) and a Databricks + Iceberg lakehouse pattern for real‑time + historical queries.
Who It Is For: Engineering leaders, data/platform teams, and SREs running high‑ingest time‑series/event workloads that must serve both live dashboards and deep historical analytics.
Core Problem Solved: Choosing a durable pattern for telemetry at scale: sub‑second application queries on fresh data, plus efficient historical analysis, without creating fragile, high‑maintenance pipelines.

How It Works

At a high level, you’re comparing two different philosophies:

TigerData: “Postgres for live telemetry” with time‑series primitives (hypertables, row‑columnar storage, tiered storage, continuous aggregates) and managed operations in Tiger Cloud. You ingest once into Postgres and query everything—real‑time and historical—with standard SQL. Optional replication to Iceberg gives you lakehouse benefits without moving the core workload off Postgres.
Databricks + Iceberg: A lakehouse focused on large‑scale analytics and ML. Telemetry flows through a streaming system (often Kafka) into cloud object storage, with Iceberg tables managed and queried by Databricks. Real‑time application queries usually hit a separate operational store or pre‑aggregated cache; deeper analytics and data science sit in Databricks notebooks and jobs.

From a telemetry perspective, the key difference is where queries land and how many systems you must keep in sync.

Ingest & Storage
- TigerData
  - Ingest telemetry (metrics, events, ticks) directly into Postgres hypertables via SQL, Kafka, or S3.
  - Time‑ and key‑based partitioning is automatic; Hypercore row‑columnar storage keeps writes fast and analytics efficient.
  - Tiered storage offloads cold chunks to low‑cost object storage, with automated compression (up to 98%).
- Databricks + Iceberg
  - Ingest via streaming (Kafka, Kinesis) or batch (S3/ADLS) into Iceberg tables on object storage.
  - Operational systems (services, OLTP databases, caches) stay separate and must be kept consistent with the lakehouse through jobs and connectors.
Real‑Time Queries
- TigerData
  - Application queries (dashboards, alerting, APIs) hit the same Postgres endpoint using SQL.
  - Hypertables + indexes + continuous aggregates give sub‑second queries across recent and historical windows.
  - Workload isolation and read replicas separate ingest from analytics when needed.
- Databricks + Iceberg
  - Most real‑time queries hit a dedicated operational database (Postgres, DynamoDB, Cassandra, etc.) or a cache (Redis).
  - Databricks SQL can serve “near real‑time” dashboards, but latency and concurrency are tied to cluster configuration and streaming job freshness.
  - You typically maintain two query paths: one for live operations, one for lakehouse analytics.
Historical Analytics
- TigerData
  - Columnar chunks + compression + continuous aggregates give efficient scans and rollups over months/years.
  - You can replicate to Iceberg for “infinite retention” and multi‑tool analytics, but your main queries can still stay in Postgres.
- Databricks + Iceberg
  - Deep analytics, ML, and ad‑hoc exploration live here: Spark/Photon engines running over Iceberg tables.
  - Great for petabyte‑scale joins, model training, and cross‑domain analytics, but not designed to be your primary OLTP or ultra‑low‑latency serving layer.

TigerData vs Databricks: Features & Benefits Breakdown

Core primitives at a glance

Core Feature / Pattern	What It Does	Primary Benefit for Telemetry
Hypertables (TigerData)	Automatic time‑ and key‑based partitioning in Postgres.	High ingest + fast time‑window queries without manual sharding.
Hypercore row‑columnar storage (TigerData)	Row for fast writes, columnar for analytics, inside Postgres.	Sub‑second queries on recent + historic data from a single SQL endpoint.
Tiered storage & compression (TigerData)	Moves cold data to object storage and compresses older chunks.	Retain years of telemetry while controlling storage cost.
Continuous aggregates (TigerData)	Incrementally maintained rollup views in SQL.	Always‑fresh dashboards/metrics without re‑scanning raw data.
Iceberg tables (Databricks)	Open table format over object storage (Parquet + metadata).	Reliable lakehouse semantics for large, slowly changing datasets.
Databricks runtime (Databricks)	Managed Spark/Photon engines for SQL, ML, and streaming.	High‑throughput batch and streaming analytics, strong for data science workloads.
Separate OLTP store (Databricks pattern)	Dedicated DB/service for real‑time reads/writes.	Keeps operations responsive, but adds integration overhead.

Ideal Use Cases

Best for TigerData (Postgres‑native live telemetry):
Because it keeps Postgres front and center and adds time‑series primitives, TigerData is ideal when:
- You need sub‑second queries across fresh and historical telemetry (seconds → months).
- Your applications speak SQL and expect Postgres semantics (transactions, joins, indexes).
- You want to avoid fragile glue—no custom mesh of Kafka, Flink, ETL, and dual‑write systems just to power dashboards.
- You still want lakehouse interoperability (replicate to Iceberg), but not as your primary serving path.
Best for Databricks + Iceberg (lakehouse‑heavy analytics & ML):
Because it optimizes Spark‑style analytics and ML over object storage, the Databricks pattern is ideal when:
- Your primary need is large‑scale offline analytics, model training, and cross‑domain joins.
- Real‑time telemetry dashboards can accept seconds to minutes of latency, or are served by a separate OLTP system.
- You already have a big data platform team comfortable operating streaming jobs, ETL pipelines, and multi‑cluster lakehouse environments.

How TigerData’s Pattern Works (Step‑By‑Step)

TigerData’s value is that it keeps the entire telemetry workflow Postgres‑native while still integrating with Iceberg when you need it.

Ingest & Model: Hypertables + indexes

You start with a standard Postgres schema, then convert your main tables to hypertables:
```
CREATE TABLE metrics (
  device_id   text,
  ts          timestamptz NOT NULL,
  metric_name text,
  value       double precision,
  tags        jsonb
);

SELECT create_hypertable('metrics', 'ts', 'device_id', 4);
```
- create_hypertable gives you automatic time/space partitioning.
- TigerData can manage default indexes for common patterns (time DESC, device_id, ts), or you can tune them:
  ALTER SYSTEM SET tsdb.create_default_indexes=false; if you want full control.
Optimize for real‑time + historical: Hypercore, compression, and tiering

As data ages, TigerData automatically shifts it through tiers:
- Row store for hot chunks (fast ingest, OLTP‑like workloads).
- Columnar store for older chunks (fast scans, aggregates).
- Compressed + tiered storage to push cold data to object storage with minimal footprint.
Example: compress and tier chunks after 7 days:
```
SELECT add_compression_policy('metrics', INTERVAL '7 days');

SELECT add_tiered_storage_policy(
  relation => 'metrics',
  older_than => INTERVAL '30 days',
  dest_tier => 'object_storage'
);
```
This gives you operational Postgres performance for recent data and warehouse‑like efficiency for older telemetry, behind a single table.
Serve queries and rollups: Continuous aggregates and workload isolation

For live dashboards, you create continuous aggregates:
```
CREATE MATERIALIZED VIEW metrics_5m
WITH (timescaledb.continuous) AS
SELECT
  time_bucket('5 minutes', ts) AS bucket,
  device_id,
  metric_name,
  avg(value) AS avg_value,
  max(value) AS max_value
FROM metrics
GROUP BY bucket, device_id, metric_name;

SELECT add_continuous_aggregate_policy(
  'metrics_5m',
  start_offset => INTERVAL '1 day',
  end_offset   => INTERVAL '1 minute',
  schedule_interval => INTERVAL '1 minute'
);
```
- Queries against metrics_5m return near‑real‑time rollups without rescanning all raw data.
- Important: continuous aggregates are incrementally refreshed. For heavy out‑of‑order data, you’ll want a refresh policy and watermark tuned to your arrival patterns.
On Tiger Cloud, you isolate workloads:
- Primary service handles ingest and transactional queries.
- Read replicas serve dashboards and analytics.
- Scale compute and storage independently, add HA, and use point‑in‑time recovery (PITR) without changing your SQL.
You can then optionally stream or replicate the same hypertables into Iceberg for offline analytics, without moving the core real‑time workload out of Postgres.

How the Databricks + Iceberg Pattern Typically Works

Ingest and land in the lakehouse
- Telemetry flows into Kafka/Kinesis.
- You run streaming jobs (Spark Structured Streaming, Flink) that:
  - Write to Iceberg tables in object storage.
  - Often write a separate copy to an operational database or cache for live queries.
Serve live queries from an operational store
- Your application talks to:
  - A Postgres/MySQL database with a subset of the telemetry.
  - A NoSQL store (e.g., Cassandra) for time‑series.
  - A cache (Redis, Memcached) for the hottest aggregates.
- Dashboards may:
  - Hit the operational store directly.
  - Query Databricks SQL with micro‑batch lag (seconds‑to‑minutes) and cluster‑dependent latency.
Run historical analytics and ML in Databricks
- Data scientists use notebooks and jobs over Iceberg tables.
- You run heavy joins, window functions, and ML frameworks (MLflow, Delta Live Tables, etc.) against large datasets.
This pattern is powerful for deep analytics but fragile for integrated real‑time + historical workloads:
- You own and operate multiple systems.
- You reconcile differences between the operational schema and the analytical schema.
- You maintain SLAs across streaming jobs, tables, and clusters.

TigerData vs Databricks: Trade‑Offs That Matter

1. Real‑time telemetry latency

TigerData
- Sub‑second queries on mixed recent + historical data.
- Same SQL, same Postgres driver, no extra serving layer.
Databricks + Iceberg
- Strong for analytics latency (seconds+), not OLTP‑grade.
- Real‑time behavior usually requires a separate operational store and/or caching.

2. Operational complexity

TigerData
- Single Postgres‑native system with managed operations in Tiger Cloud.
- No separate streaming query engine for most telemetry workloads.
- Optional integration with Iceberg for lakehouse workflows, but not required for core operations.
Databricks + Iceberg
- Multiple moving parts: streaming system, operational DB, object storage, Databricks clusters.
- “It worked, but it was fragile and high‑maintenance” is a common description of dual‑path architectures.

3. Cost and scaling model

TigerData
- Scale a single Postgres‑native service: hypertables + compression + tiering.
- On Tiger Cloud, you:
  - Scale compute/storage independently.
  - Don’t pay per‑query, per‑ingest‑event, or for automated backups.
  - Get transparent, itemized billing.
Databricks + Iceberg
- Pay for:
  - Databricks compute (clusters, SQL warehouses).
  - Storage (object storage for Iceberg tables).
  - Additional infra (Kafka, separate operational DBs, caches).
- High flexibility, but cost is tied to cluster size, runtime hours, and pipeline complexity.

4. Tooling and ecosystem

TigerData
- Fully Postgres‑compatible: drivers, ORMs, SQL tools “just work.”
- Vector/AI patterns via Postgres extensions (e.g., pgvector) and hybrid retrieval in the same database as telemetry.
- Lakehouse integration for Iceberg lets you keep using Databricks or other engines when needed.
Databricks + Iceberg
- Strong ecosystem for Spark, ML, and multi‑language analytics (Python, Scala, SQL, R).
- Works well as a central analytics hub for many domains, not only telemetry.

Limitations & Considerations

TigerData limitations / considerations:
- Ultra‑long‑retention deep analytics only: If your primary workload is offline batch analytics over tens of petabytes with complex ML pipelines and minimal real‑time requirements, you might lean toward a dedicated lakehouse as your center of gravity and use TigerData as a specialized operational store.
- Cross‑cloud multi‑system governance: If you already standardized governance and access controls around a single lakehouse layer, introducing another “source of truth” requires a clear replication and catalog strategy (TigerData → Iceberg).
Databricks + Iceberg limitations / considerations:
- Real‑time OLTP behavior: Databricks SQL is not an operational database. For millisecond‑level reads/writes and high‑QPS telemetry dashboards, you will need a separate serving layer.
- Integration and maintenance overhead: Running streaming jobs, reconciling schemas, and maintaining dual data paths (operational + analytical) is non‑trivial. You’ll need dedicated platform expertise.

Pricing & Plans (Tiger Cloud framing)

For TigerData, think in terms of database services, not per‑query or per‑scan pricing. Exact numbers depend on your region and configuration, but the model is:

You provision a Tiger Cloud service (size, storage, HA options).
You can scale compute and storage independently.
Automated backups, PITR, and internal networking are included—no separate line items for backups or per‑query charges.
Billing is monthly in arrears, with clear usage breakdowns in Tiger Console.

An approximate plan split looks like:

Performance: Best for teams needing high ingest + real‑time dashboards with clear SLAs, but not yet at massive multi‑petabyte scale. Ideal when you’re consolidating from “plain Postgres + caching” to a Postgres‑native telemetry platform.
Scale / Enterprise: Best for organizations with very high ingest (billions to trillions of metrics per day), multi‑region or regulated workloads, and requirements like SOC 2 reports, GDPR support, and HIPAA (on Enterprise). You typically get HA, read replicas, private networking (VPC peering/Transit Gateway), and 24/7 support with severity‑based response times.

For Databricks + Iceberg, pricing spans:

Databricks compute units for clusters and SQL warehouses.
Object storage for table data.
Additional cost for streaming infra (Kafka/Kinesis), operational DBs, and caches.
You’ll want to model end‑to‑end TCO, not just storage/compute in the lakehouse.

Frequently Asked Questions

Should we centralize all telemetry in Databricks + Iceberg and only use TigerData as a small operational store?

Short Answer: Only if your primary value is offline analytics/ML and you’re comfortable running separate real‑time infrastructure.

Details:
If most of your business value comes from large‑scale analytics and ML (many domains, long retention, complex joins) and your real‑time telemetry needs are modest, then centralizing data in Iceberg and using a smaller operational store can work. But this usually means:

Maintaining at least two systems for telemetry: Databricks + an OLTP DB or cache.
Building and maintaining streaming jobs and ETL to keep them in sync.
Accepting higher operational overhead for dual data paths.

If your applications and SRE workflows depend on fast, always‑on telemetry queries, it’s usually cleaner to:

Treat TigerData as the system of record and primary real‑time interface.
Replicate into Iceberg (via TigerData’s lakehouse integration) for broader analytics and ML, rather than the other way around.

Can TigerData fully replace Databricks for telemetry analytics?

Short Answer: For most real‑time + historical telemetry workloads, yes. For heavy cross‑domain big‑data ML at multi‑petabyte scale, TigerData complements rather than fully replaces Databricks.

Details:
TigerData is built specifically for time‑series, event, and tick data. It has:

Proven scale (“1 QUADRILLION data points stored,” “3 TRILLION metrics per day” on a single service).
Sub‑second queries on live + historical windows using continuous aggregates and columnar storage.
Postgres‑native vector and search patterns for RAG and AI agents.

For application‑centric telemetry workloads (monitoring, observability, product analytics, IoT, Web3):

TigerData can be your primary system for both real‑time dashboards and historical analysis.
You can add lakehouse replication when you need to join telemetry with many other domains, share data with multiple compute engines, or run heavy ML outside Postgres.

For broader enterprise‑wide analytics spanning dozens of domains with heavy ML, Databricks remains valuable. The best pattern in that scenario is typically:

Use TigerData as the operational telemetry engine.
Stream/replicate telemetry into Iceberg and access it via Databricks for organization‑wide analytics and ML.

Summary

For real‑time + historical telemetry, you’re ultimately choosing where to anchor your architecture:

TigerData gives you a Postgres‑native platform that handles high ingest, sub‑second queries, and long‑term retention in a single system. Hypertables, row‑columnar storage, compression, tiering, and continuous aggregates turn Postgres into an application‑grade telemetry engine. Lakehouse integration with Iceberg is additive, not mandatory.
Databricks + Iceberg gives you a powerful lakehouse for broad analytics and ML over massive datasets, but you’ll almost always need separate infrastructure for real‑time application queries—and you’ll own the integration between those worlds.

If your priority is low‑latency telemetry queries, operational simplicity, and Postgres compatibility, TigerData is usually the better center of gravity, with Iceberg as an extension. If your priority is cross‑domain big‑data analytics and ML, and you already operate a lakehouse, Databricks remains a strong choice—with TigerData as the specialized engine for your most demanding telemetry paths.
