Fundamentals

Connection

• A connection is a handle to a WiredTiger database instance.

Session

• A session defines the context for most operations performed in WiredTiger.

Cursor

• Cursors are used to get and modify data.

Transactions

• Transactions provide a powerful abstraction for multiple threads to operate on data concurrently.

Timestamps

• The timestamp data model.

Snapshot

• Snapshots are implemented by storing transaction ids committed before the transaction started.

Rollback to Stable

• Rollback the database to a stable state by removing data that is beyond the stable timestamp.
