Abstract
A storage node may organize a database by storing current data in a balanced tree structure and storing prior data in a log structure. The storage node may update the database by replacing old data in the balanced tree with new data from a write and writing the old data to the log structure. The storage node may be able to locate appropriate date to respond to time-specific queries using the balanced tree structure and the log, and may be able to locate and remove old data with minimal computational resources.
