High-Performance Data Pipelines with ClickHouse, PostgreSQL, and CouchDB on VPS

Why ClickHouse + PostgreSQL + CouchDB?

• ClickHouse is a high-performance, columnar OLAP database designed for real-time analytics, log processing, time-series data, and large-scale aggregations. Its vectorized query execution, data compression, and ability to process billions of rows in milliseconds make it ideal for analytics dashboards and IoT pipelines.
• PostgreSQL excels at transactional (OLTP) workloads and hybrid data models.
• CouchDB is a document-oriented NoSQL database, perfect for flexible JSON storage and high-speed writes with eventual consistency.
• By syncing operational data from CouchDB into PostgreSQL and ClickHouse, you get the best of both worlds — fast transactions and lightning-fast analytics — without relying on expensive managed cloud services.

Real-Time Event Streaming

We replicate CosmosDB Change Feed → Synapse-like pipelines using:

• CouchDB’s _changes feed to detect real-time updates.
• Kafka for high-throughput, fault-tolerant event streaming, capable of processing millions of messages per second.
• ClickHouse to run instant analytics queries (aggregates, trends, time-series) on fresh data.
• PostgreSQL for relational joins, metadata storage, or mixed OLTP/OLAP scenarios.

Why VPS for ClickHouse?

• Full Ownership: You have root-level control of performance tuning, schema design, and caching — something cloud vendors often restrict.
• Cost Efficiency: ClickHouse performs extremely well on commodity hardware. Various VPS providers offer high IOPS SSDs at a fraction of AWS or GCP pricing.
• Elastic Scalability: Add or remove nodes easily with Docker Swarm or Kubernetes, taking advantage of ClickHouse’s distributed cluster features.
• Compression and Speed: With LZ4/ZSTD compression and columnar storage, ClickHouse significantly reduces storage costs and query response times.

Why ClickHouse Over MariaDB ColumnStore?

• 10–100x faster query performance due to its vectorized query engine.
• Superior compression (up to 10x reduction in storage size).
• True real-time analytics — columnar engines like ClickHouse are built for speed, unlike MariaDB ColumnStore which is better suited for batch workloads.
• Extensive ecosystem: Built-in support for time-series, materialized views, aggregating indexes, and window functions.
