Abstract
A system for an in-memory row storage architecture can be provided. In some implementations, the system performs operations comprising processing a database transaction affecting at least a first row in an in-memory row store and at least a second row in a persistent page store, logging changes to the second row within a page store transaction log as part of the processing and prior to committing the database transaction, logging a final aggregated result of the first row as part of committing the database transaction within a row store transaction log that is separate and distinct from the page store transaction log, and altering at least a portion of the in-memory row store based on accessing the row store transaction log. Related systems, methods, and articles of manufacture are also described.
