This guide explains the underlying snapshot and transaction‑log storage of ZooKeeper, outlines three key scenarios for using MSE’s import‑export feature, and provides step‑by‑step instructions with code snippets to back up, migrate, or analyze ZooKeeper clusters efficiently.
This article explains why ZooKeeper can run out of disk space due to excessive snapshots and transaction logs, describes the underlying file‑generation mechanism, and provides concrete configuration parameters and best‑practice recommendations to control file growth and keep the cluster stable.
The article explains the fundamentals of Change Data Capture (CDC), describing how capturing DML changes from relational databases like MySQL or PostgreSQL can provide incremental, near‑real‑time data for analytics and reporting while preserving source performance, and outlines modern CDC architectures, transaction‑log based extraction, and production‑ready design considerations.
This article explains the three core MySQL logs—binlog, redo log, and undo log—their structures, formats, configuration parameters, and how they work together to provide replication, crash recovery, and transactional atomicity while balancing performance and consistency.
This article presents three common MySQL interview questions—whether query fields are case‑sensitive, how InnoDB implements transactions and logs, and the different binlog formats—along with detailed explanations, configuration examples, and SQL code snippets for each scenario.
