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.

WiredTiger Architecture

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 should be generally portable to any 64-bit system supporting the ANSI C99, POSIX 1003.1 and POSIX 1003.1c (threads extension) standards.
