Memgraph Storage Modes Explained

Memgraph, an in-memory graph database, offers three distinct storage modes to cater to different performance and data management needs. The default in-memory transactional storage mode ensures high performance with ACID compliance, maintaining data integrity through Delta objects, snapshots, and write-ahead logs (WAL). For users prioritizing fast data import and reduced memory overhead, the in-memory analytical storage mode disables Delta objects, improving write performance but sacrificing ACID guarantees. The on-disk transactional storage mode, utilizing RocksDB, is designed for datasets larger than available RAM, balancing disk storage with in-memory analysis while maintaining snapshot isolation. Each mode has unique trade-offs, affecting aspects like transaction isolation and durability, and should be chosen based on specific requirements and dataset size, with the on-disk mode still being experimental.
