The latest version of Neo4j 5 Enterprise Edition (v.5.14) introduces a new storage engine called Block format, which significantly increases the efficiency of graph-native storage. The new format lays out data on disk in a structure that reduces fragmentation and improves performance by up to 40% compared to the existing Record format. With better memory usage, processing queries requires less memory, and storage is more compact, allowing for faster query execution. The Block format beta version is now available, with the general availability (GA) release expected early in 2024. Users can migrate or copy their databases to the new format using various commands, and performance tests show significant improvements over Record format across different scenarios. Despite some limitations, such as offline conversion for large databases and lack of incremental bulk import, the Block format is a major leap forward in graph-native database technology.
