SQLite WAL2 Mode for Microservice Read-Replication: Achieving 500,000 Reads/sec on Local NVMe
The proposed Write-Ahead Log 2 (WAL2) extension for SQLite introduces multi-writer and advanced replication capabilities, reshaping the database's role in high-throughput microservices. By leveraging local NVMe storage architectures, engineering benchmarks reveal a path toward 500,000 read operations per second without the traditional network overhead of client-server databases.
