Our Proven Oracle to ClickHouse Migration Delivers Fixed Scope and Senior Engineers
Migrating Oracle Database to ClickHouse is a well-understood project. We assess your legacy log databases and timeseries metrics, design a columnar schema, and execute a fixed-scope migration in 4–8 months with 2–4
The lowest-cost way off Oracle Database: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.

- ✓Keep Oracle vendor support while you plan the move
- ✓40–70% savings on legacy platform support during transition
- ✓24/7 US-based support for post-migration stability
- ✓Reduce query times for log analysis and metrics reporting

Frequent data mutations (inserts/updates/deletes)
ClickHouse handles mutating data with engine families like ReplacingMergeTree. Our engineers map your legacy update patterns to ClickHouse’s append-friendly model — no loss of functionality.
Deep SQL windowing functions with custom variables
Yes, ClickHouse supports window functions and array functions. We convert your complex Oracle queries to ClickHouse equivalents, preserving analytical logic.
Legacy reporting systems incompatible with columnar interfaces
We rebuild your reporting layer to work with ClickHouse’s JDBC/ODBC connectors and popular BI tools. Your dashboards stay intact.
Oracle Database → ClickHouse migration — your questions answered
Do we need to cut over to ClickHouse immediately?+
No. Your Oracle Database stays under vendor support as long as your vendor contract is active. You migrate on your timeline in phases.
What if our Oracle support lapses before we finish?+
Our third-party support covers most operational issues on the legacy platform (excluding vendor patches) while you complete the move.
Can ClickHouse handle our high-cardinality timeseries data?+
Yes. ClickHouse’s columnar storage and vectorized execution deliver sub-second queries on billions of rows—ideal for IoT, cybersecurity, and telecom telemetry.
How do you handle complex Oracle SQL with window functions?+
We map your queries to ClickHouse’s window functions and arrayJoin. Our senior engineers test every query in a proof-of-concept before migration.
