WiredTiger is an high performance, scalable, production quality, NoSQL, Open Source extensible platform for data management.WiredTiger supports row-oriented storage (where all columns of a row are stored together), and column-oriented storage (where columns are stored in groups), allowing for more efficient access and storage of column subsets. Additionally, WiredTiger supports log-structured merge trees (LSM), for sustained throughput under random insert workloads.

WiredTiger includes ACID transactions with standard isolation levels and durability at both checkpoint and fine-grained granularity.

WiredTiger can be used as a simple key/value store, but also has a complete schema layer, including indices and projections.

This documentation describes the programming interface to WiredTiger used by developers to construct applications. We follow SQL terminology: a database is set of tables managed together. Tables consist of rows, where each row is a key and its associated value. Tables may optionally have an associated schema, splitting the value into a set of columns. Tables may also have associated indices, each of which is ordered by one or more columns.

WiredTiger distributions are tested on Linux, FreeBSD and OS X. WiredTiger is portable to any 64-bit system supporting the ANSI C99, POSIX 1003.1 and POSIX 1003.1c (threads extension) standards.
