Bigtable is a distributed storage system for petabyte-scale structured data across thousands of commodity servers, providing a sparse, distributed, persistent multi-dimensional sorted map that influenced the NoSQL revolution.

Change Data Capture (CDC) captures row-level changes in databases and streams them to downstream systems in real time. This module covers log-based CDC (Debezium, AWS DMS), query-based CDC, and trigger-based approaches, practical deployment with Kafka Connect and Pulsar, and 2025-2026 trends including peerDB for Postgres CDC, Snowpipe Streaming, and the convergence of CDC with real-time analytics architectures.

Platform version history and notable changes.

AI agents are making it easier for the public to interact with government, such as by helping them apply for benefits, understand complex policies, and make their opinions heard. Although improving se

A comparison argument for choosing DuckDB over SQLite. Where SQLite is a row-oriented OLTP engine optimized for point lookups and transactional writes, DuckDB is a columnar, vectorized OLAP engine designed for analytical queries over large datasets. Includes the practical implications for aggregate-heavy workloads, Parquet reads, and in-process analytics.

Collier empirically analyzes the UK SARs database, documenting the massive growth in SAR filings, low conversion rates to law enforcement action, and the 'defensive filing' phenomenon.
