WiredTiger is a high-performance, scalable, transactional, open-source NoSQL data engine for data management.Read 8 Oct 2026 · source.wiredtiger.com

Support

The project directs users to its user group and [email protected], and says to contact MongoDB for technical support.Read 8 Oct 2026 · source.wiredtiger.com

Maker

WiredTiger is developed and maintained by MongoDB, Inc., where it is the principal database storage engine.Read 8 Oct 2026 · source.wiredtiger.com

Capacity

The overview states support for petabyte tables, records up to 4 GB, and 64-bit record numbers.Read 8 Oct 2026 · source.wiredtiger.com

Compression

Block compression can be selected per table, and the documentation says it typically reduces information written to disk by 30–80%.Read 8 Oct 2026 · source.wiredtiger.com

Concurrency

Its optimistic concurrency control avoids a centralized lock manager, and transactional operations in one thread do not block operations in other threads.Read 8 Oct 2026 · source.wiredtiger.com

Data integrity

The engine includes end-to-end checksums, data verification, and salvage support, and its no-overwrite design protects against operating-system and hardware-level torn writes.Read 8 Oct 2026 · source.wiredtiger.com

Portability

The reference guide says WiredTiger should generally be portable to 64-bit systems supporting ANSI C11 and POSIX 1003.1, and links to build instructions for Linux, BSD, OS X, and Windows.Read 8 Oct 2026 · source.wiredtiger.com

Schema

It can be used as a key/value store and includes a schema layer with indexes and projections.Read 8 Oct 2026 · source.wiredtiger.com

Storage formats

It supports row-oriented and column-oriented storage, as well as log-structured merge trees.Read 8 Oct 2026 · source.wiredtiger.com

Tiered storage

Tiered storage is documented as experimental and not developed, tested, or tuned for production scenarios.Read 8 Oct 2026 · source.wiredtiger.com

Transactions

It provides ACID transactions with standard isolation levels and checkpoint-level or commit-level durability.Read 8 Oct 2026 · source.wiredtiger.com
