Wow! Kalian Wajib Tahu Database Ini : ClickHouse
Pernah dengar database yang bisa scan MILIARAN baris data dalam hitungan detik? Namanya ClickHouse — dan kalau kamu kerja dengan data, kamu WAJIB tahu database ini.Di video ini kita nggak cuma teori. Kita bangun langsung pipeline data
lengkap dari nol: data transaksi dari PostgreSQL mengalir secara real-time
ke ClickHouse, lalu kita eksplorasi kekuatan analitiknya lewat dashboard
demo yang interaktif.
Yang akan kamu pelajari di video ini:
✅ Beda OLTP vs OLAP — kenapa satu database saja tidak cukup
✅ Change Data Capture (CDC) — sinkronisasi data real-time tanpa batch ETL
✅ Debezium — menangkap setiap perubahan dari PostgreSQL
✅ Apache Kafka — message broker sebagai jembatan data
✅ ClickHouse — database OLAP columnar yang super cepat
✅ Fitur-fitur ClickHouse: Streaming analytics, Funnel, Distribution, Pre-Aggregation, sampai Time Travel
Pipeline yang kita bangun:
PostgreSQL (OLTP) → Debezium → Apache Kafka → ClickHouse (OLAP)
ClickHouse bukan pengganti database transaksional — dia pelengkap. Setelah nonton video ini, kamu bakal paham kapan dan kenapa harus pakai database OLAP, dan betapa powerful-nya ClickHouse untuk kebutuhan analytics.
