Abstract
A database management system maintains a collection of data using a log-based storage structure. In response to a request to store data items (key-value pairs), the database management system stores mapping information to a data item in an in-memory data structure while the data items are stored on the log-based storage structure. The hash of the key includes information to identify an index entry that comprises information that maps to the location of the data item stored on the log-based storage structure.
