A dictionary data structure is defined and stored on the disk storage system. Key-value pairs can be inserted and deleted into the dictionary data structure, with full transactional semantics, at a rate that is faster than one insertion per disk-head movement. Keys can be looked up with only a logarithmic number of transfers, even for keys that have been recently inserted or deleted. Queries can be performed on ranges of key-value pairs, including recently inserted or deleted pairs, at a constant fraction of the bandwidth of the disk. The dictionary employs indirect logging for physical block logging."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Disk-resident streaming dictionary","description":"A method, apparatus and computer program product for storing data in a disk storage system is presented.
