Batching Like a Pro

The blog post discusses the advantages of migrating from APOC's `apoc.periodic.iterate` procedure to Cypher's `CALL {…} IN TRANSACTIONS` (CIT) for handling bulk data operations in Neo4j. APOC has traditionally been used to manage transactional data operations while avoiding out-of-memory (OOM) errors by allowing control over batch sizes. However, CIT has evolved to offer similar functionalities with additional benefits such as improved memory tracking, error handling, and enhanced readability and error detection capabilities through Cypher's tooling. CIT provides a more modern and efficient approach by simplifying query planning and execution, offering built-in query statistics, and handling entity transactions more effectively, thus reducing the risk of OOM errors and improving performance. The post highlights the ongoing improvements and support for CIT, contrasting it with APOC's maintenance mode status, and suggests that switching to CIT provides a cleaner, more reliable, and future-proof solution for managing complex queries in Neo4j.
