ClickHouse Blog
2 updatesClickHouse describes why Postgres and ClickHouse are becoming the default combination for AI applications, which demand real-time transactions and analytics on massive data volumes. The post covers AI's data-growth demands, the collapse of traditional OLTP/OLAP boundaries, and ClickHouse's investments in tools like PeerDB/ClickPipes for CDC, pg_clickhouse for cross-database querying, and pg_stat_ch for observability.
Article explores how chDB (ClickHouse embedded) can serve as a local data engine for AI agents, reducing latency and instability from network calls by embedding a full query engine in the agent process. Covers three use cases: agent memory using append-only MergeTree with vector search, chDB as a federation hub, and token/cost savings from eliminating network failures and retry loops.
