Compatibility and Load Testing for Temporal Self-Hosted with CockroachDB Cloud

#cockroachdb #temporal

A proof-of-concept validating CockroachDB Cloud as a persistence backend for a self-hosted Temporal deployment.

What and Why

Temporal isn't on CockroachDB's official support matrix. It ships a postgres12 persistence plugin designed and tested against real PostgreSQL — not CockroachDB specifically. Before recommending CockroachDB as a backend for a self-hosted Temporal deployment, two questions need real answers rather than assumptions:

  1. Does it actually work? CockroachDB is PostgreSQL-wire-compatible, but wire compatibility isn't the same as full SQL-dialect compatibility. Temporal's schema and query patterns need to be validated end-to-end.

  2. What cluster size do I need to provision? Temporal persists every workflow state transition as a durable "checkpoint" (a history event). Sizing a cluster for a given checkpoint volume requires real, measured bytes-per-checkpoint data — not a vendor estimate.

This post documents the compatibility issues found and fixed, the load-testing methodology used to generate real data at scale, the results, and a reusable formula for extrapolating those results to any target checkpoint volume.

Architecture

Test environment:

  • MacBook Pro (Apple M3 Pro, 18 GB RAM)
  • Temporal Server v1.31.2 (self-hosted binary running locally on my laptop)
  • Temporal CLI v1.7.3
  • CockroachDB Cloud Advanced: 3 nodes, AWS us-east-1, 16 vCPU / 64 GiB RAM per node, v26.2.3

CockroachDB as persistence backend, via Temporal's postgres12 SQL plugin, split across two databases:

  • temporal — workflow execution state and event history (executions, history_node, history_tree, task-queue tables)
  • temporal_visibility — the queryable, denormalized index used by dashboards, CLI, and search (executions_visibility)

Simulated workload: This project simulates a Temporal workload for an e-commerce application that specializes in return-automation and post-purchase platform. A post-purchase return-automation saga — return eligibility check (an AI-classification activity), a package-protection branch, a signal-driven wait for physical package receipt with an SLA timer, an AI-driven disposition decision (refund / exchange / store credit), the disposition activity itself with saga-style compensation on failure, and customer notification. Built to be representative of a real branching saga, not a synthetic microbenchmark — average ~32 checkpoints per execution, ranging 12–45 depending on branch taken. Full reference implementation is in the appendix.

Compatibility Issues Found and Fixed

Temporal's schema migrations for temporal_visibility (versions v1.2 through v1.13) hit six distinct CockroachDB/PostgreSQL incompatibilities. All were fixed by patching the migration SQL files directly — no application-code changes, no fork of Temporal itself.

A separate, non-schema finding: default numHistoryShards: 4 caused severe workflow-task contention under concurrent load (context deadline exceeded, WorkflowTaskTimedOut cascades) — not a CockroachDB limitation, but an under-provisioned Temporal-side setting for the target throughput. Raising to numHistoryShards: 256 (512 is recommendation for production) increases write throughput and increases number of concurrent persistence calls.

Load Testing Methodology

Rather than relying on a single small sample, checkpoints were generated in escalating batches (100 → 1,000 → 5,000 → 20,000+) with verification at each stage:

  1. Smoke test (10–20 executions) to validate correctness end-to-end
  2. Staged batches, each followed by:

  • temporal workflow count --query "ExecutionStatus='Running'" to confirm full drain

  • Direct SQL against temporal/temporal_visibility for real execution/checkpoint counts (not estimates)

  • CockroachDB Cloud Console storage metrics per table

  1. Final run: 34,000+ total executions, exceeding the 1,000,000-checkpoint target

A custom batch.py script drove load: bounded-concurrency workflow starts with immediate signaling, fire-and-forget (no blocking on completion at scale), self-reporting throughput. A tuned worker.py (moderate max_concurrent_activities/max_concurrent_workflow_tasks, sized to the test laptop's cores/RAM.

Verification queries in CockroachDB 

-- Full drain confirmation, cross-checked in SQL
USE temporal_visibility;
SELECT status, count(*) FROM executions_visibility
WHERE namespace_id = '<your-namespace-id>'
GROUP BY status;

-- Real checkpoint totals -- the actual sizing data, not an estimate
USE temporal;
SELECT
  count(*) AS total_executions,
  sum(next_event_id - 1) AS total_checkpoints,
  avg(next_event_id - 1) AS avg_checkpoints_per_execution
FROM executions e JOIN namespaces n ON n.id = e.namespace_id
WHERE n.name = 'default';

-- Logical (uncompressed, single-copy) bytes per checkpoint
SELECT
  (SELECT sum(pg_column_size(data)) FROM history_node) AS total_logical_bytes,
  (SELECT sum(next_event_id - 1) FROM executions e JOIN namespaces n ON n.id = e.namespace_id
     WHERE n.name = 'default') AS total_checkpoints,
  (SELECT sum(pg_column_size(data)) FROM history_node)::FLOAT
    / NULLIF((SELECT sum(next_event_id - 1) FROM executions e JOIN namespaces n ON n.id = e.namespace_id
       WHERE n.name = 'default')::FLOAT, 0)
    AS avg_logical_bytes_per_checkpoint;

-- Read/write mix, from actual observed statement statistics
SELECT
  metadata->>'db' AS database_name,
  left(metadata->>'querySummary', 6) AS verb,
  sum((statistics->'statistics'->>'cnt')::INT) AS total_executions
FROM crdb_internal.statement_statistics
WHERE metadata->>'db' IN ('temporal', 'temporal_visibility')
  AND metadata->>'stmtType' = 'TypeDML'
GROUP BY 1, 2
ORDER BY total_executions DESC;
Enter fullscreen mode Exit fullscreen mode

Results

Final measured totals (34,000+ executions):

The ~2.2x gap between logical (140 bytes) and physical (~308 bytes) per-checkpoint size reflects CockroachDB's replication factor and index overhead — a legitimate planning multiplier, not compression failure.

A notable finding: temporal_visibility (Advanced Visibility's SQL-based schema) consumed more physical storage than temporal itself in our tests, despite holding far less raw data.

Read/write mix (from crdb_internal.statement_statistics, temporal DB): 56% SELECT, 23% INSERT, 15% UPDATE, 6% DELETE. Reads are the majority — Temporal's optimistic-concurrency design requires a consistency-check read before most writes.

Extrapolating to Your Own Workload

Use the measured per-unit rates above with your own target volume:

This work validates that CockroachDB Cloud Advanced functions correctly as a persistence

  • Each checkpoint is a transaction in CockroachDB and the heuristic is 1 vCPU : 150 TPS
  • executions/month = checkpoints_per_month ÷ avg_checkpoints_per_execution
  • temporal DB storage = checkpoints_per_month × 308 bytes
  • temporal_visibility size = executions_per_month × 13,300 bytes
  • steady-state storage (N-day retention) = (temporal + temporal_visibility) × (retention_days ÷ 30)
  • recommended total = steady-state storage × 1.30-1 (headroom: fragmentation, non-uniform load, growth margin)
  • storage per node = recommended total ÷ node count

Disclaimer

This work validates that CockroachDB Cloud Advanced functions correctly as a persistence backend for self-hosted Temporal, given the schema patches documented above, and provides real measured data for capacity planning. Temporal is not on CockroachDB's official support matrix. This is compatibility-validated proof-of-concept work, not an officially supported or vendor-certified deployment pattern. Production adoption should include an engineering review of the schema patches, ongoing monitoring for behavior differences from Temporal's tested PostgreSQL backend, and the load-test validation flagged above before committing to a final cluster size.

"""
Return-Automation Saga Workflow
================================
Simulates a post-purchase return/exchange/store-credit platform as a
durable Temporal saga. Designed to generate a realistic, varied checkpoint
(event history) shape for CockroachDB storage sizing.

Saga shape:
    ReturnInitiated
      -> EligibilityCheck (rules + AI classification activity)
      -> PackageProtectionCheck (branch)
      -> wait for carrier "package received" signal (with SLA timer)
      -> DispositionDecision (AI agent activity: refund/exchange/store-credit)
      -> disposition activity (with compensation on failure)
      -> CustomerNotify
    Concurrently: SupportEscalation signal can arrive at any point and
    short-circuits to a human-handled resolution path.

Each Activity call, Timer, and Signal is one or more durable checkpoints
(history events) persisted to CockroachDB via the `temporal` database.
