The log may be stored to disk for persistence. Insertions of new records into the log may occur sequentially to ensure adequate performance. The index tree may be maintained in memory for performance. When the log is full, log records may be written in key-sorted order to a new tablet in a tablet library. Two tablets may be merged from time to time. Merging may include iteratively performing a plurality of atomic merges for each of a plurality of atomic portions. During atomic merges, tablet index data may be modified in copy-on-write fashion to preserve existing data until the atomic merge completes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maintaining I/O transaction metadata in log-with-index structure","description":"An information handling system maintains a log-with-index (LWI) structure that includes a log for inserting and deleting records, each of which includes a key, and a binary index for maintaining an in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10509780","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
