From Neon Postgres to ClickHouse Managed Postgres
Blog post from ClickHouse
ClickHouse describes how three organizations—logistics startup Shipsidekick, social intelligence platform socialpruf., and educational publisher Infinitas Learning—migrated production PostgreSQL workloads from Neon to ClickHouse Managed Postgres after reporting reliability, performance, support, scaling, and network-transfer-cost concerns. The companies said the move improved uptime, query consistency and speed, connection handling, cache performance, and infrastructure costs, with Infinitas reporting p99 latency falling from seconds to single-digit milliseconds and socialpruf. reporting roughly 30% faster queries overall. Each used ClickPipes for schema transfer, parallel initial loading, and change data capture before scheduling production cutovers, completing migrations ranging from several hours to under 16 hours for databases as large as 750 GB. The account attributes the reported performance gains partly to local NVMe storage and notes that colocating PostgreSQL and ClickHouse can remove transfer charges for analytics pipelines, while also outlining migration considerations involving replication setup, application drivers, connection pooling, unsupported schema changes during CDC, and differences in branching behavior.
