Ingest your data
into ClickHouse from day one
Backfill historical data, keep CDC in sync, handle schema changes, normalize messy data, and keep ClickHouse queries correct.



The Problems
Most ClickHouse projects break
in the first 30 days
ClickHouse queries are fast but getting correct data into ClickHouse is the hard part. Most teams face these issues:
Historical backfills are painful
You need old PostgreSQL, MySQL, or MongoDB data in ClickHouse before your analytics are useful. But historical imports usually break when live updates start.
Keeping ClickHouse continuously synced from Postgres WAL, MySQL binlog, MongoDB, or Debezium quickly becomes messy. Teams end up maintaining custom glue code.
CDC becomes fragile
Historical imports and CDC running together create race conditions. Older rows overwrite newer state. Your analytics become inconsistent.
Backfills overwrite live updates
Data plane and. control plane separated. We manage upgrades, orchestration, reliability, and operations while your data stays in your infrastrucure.
