This post details how Bolt uses ksqlDB for data replication to their data warehouse. It covers the requirements for a data replication pipeline (consistency, resilience, scalability, data manipulation, denormalization, integration) and explains why ksqlDB was chosen over other solutions. The post provides concrete ksqlDB SQL examples for creating streams from topics, selecting and filtering data, and merging streams. It also elaborates on ksqlDB's advantages: native Kafka integration, ease of deployment and management, linear scalability, Schema Registry integration, declarative query language, extensibility with UDFs, and ease of stream management.
