Understanding whether your PostgreSQL database is dominated by read or write operations is crucial for effective tuning and scaling. This deep dive reveals how to analyze workload patterns using internal statistics and provides targeted optimization strategies for each scenario. Learn why treating reads and writes as equal metrics is a critical mistake and how to leverage Postgres' internal metadata for actionable insights.

Sentry solved the database performance nightmare of analyzing billions of unstructured performance spans by applying classic hash table principles to ClickHouse. Their innovative bucketing strategy reduced query times from seconds to milliseconds, unlocking real-time observability at scale. This breakthrough now powers critical features like custom dashboards and distributed tracing across their platform.

ClickHouse reimagines row-level updates by transforming them into high-speed inserts, leveraging its MergeTree architecture to avoid the traditional pitfalls of column stores. This deep dive explores purpose-built engines like ReplacingMergeTree and CollapsingMergeTree, revealing how they enable real-time data mutations without sacrificing analytical performance. For developers grappling with IoT, e-commerce, or financial data streams, this design offers a scalable path to handling volatile datasets.

A revealing Hacker News discussion showcases how PostgreSQL's native features—trigram search, full-text indexing, and materialized views—can power robust search engines, challenging the need for complex external systems like Elasticsearch. This approach offers developers a compelling path to reduce infrastructure overhead while maintaining performance and relevance for many applications.
