ClickHouse Data Migration.
Migration to ClickHouse Cloud, powered by Shinro (our AI-assisted migration platform) with ClickHouse experts from Quest1 in the loop.
What it is.
A full-lifecycle migration engagement where Quest1 takes your existing analytical store to ClickHouse Cloud. The engagement combines Shinro (Quest1's proprietary AI-assisted migration platform) with Quest1 engineers who own the decisions the tool can't, won't, or shouldn't automate.
The work covers the full arc: assessment of the existing stack, target architecture design, infrastructure setup, application code analysis and remediation, schema and DDL translation, bulk and CDC data migration, dual-write cutover, validation, and post-migration optimization. Shinro handles the deterministic work fast (profiling, schema generation, code analysis, data validation). Quest1 engineers handle the consequential calls (architecture, sort key design, cutover sequencing, risk acceptance).
The deliverable is a production ClickHouse Cloud deployment with your application cut over, your team trained, and your old system safely decommissioned.
How we engage.
Four phases. Each phase ends when its decisions are made and proven.
Shinro Profiler maps the existing analytical store: data volume, query patterns, schema complexity, version compatibility, application dependencies. Quest1 engineers translate that into a target ClickHouse Cloud architecture with cluster topology, HA/DR posture, ClickPipes ingestion plan, and a sized cost model. The phase resolves when the target architecture is decided and the risks are named.
Infrastructure provisioned (SSO, replication, backup). Shinro Code Analyzer scans application code for ClickHouse incompatibilities with severity-graded remediation. Shinro Migrator generates ClickHouse-native schema and DDL, runs the pilot, then orchestrates bulk and CDC data movement through ClickPipes. The phase resolves when the data and schema are migrated and the pilot holds.
Dual-write across old and new, gradual traffic shift, final cutover, and decommission. Shinro Validator runs per-table row-count and aggregate consistency checks; Quest1 engineers own the cutover sequence and rollback path. The phase resolves when the new system is serving and the old one is safely retired.
Sort keys, materialized view chains, partitioning, TTL, memory configuration. Application refactoring to use ClickHouse-native features. Auto-scaling and alerting configured to your operational baseline.
What you get.
Who this is for.
Teams who have committed to ClickHouse Cloud, or are close to. Most useful when you're migrating from another analytical store and want the work done with engineering rigor rather than scripts and spreadsheets, running on a deadline (compliance, infrastructure sunset, cost ceiling) where months of manual migration isn't an option, or scaling beyond what your current deployment can support.
Why Quest1.
Shinro is Quest1's proprietary AI-assisted migration platform. It profiles the source system, analyzes application code for incompatibilities, generates ClickHouse-native schema and DDL, orchestrates the data move, and validates results per table. The platform compresses the time and risk of the deterministic work. Quest1 engineers own the architecture decisions, cutover sequencing, and edge cases. As one of the earliest services partners in the ClickHouse ecosystem, our team carries depth that doesn't appear in documentation.
