Abstract
A data store maintaining data may implement reducing input/output (I/O) operations for on-demand data page generation. Log records may be maintained for data pages of data describing changes to the data pages. A coalesce operation may be performed when log records for a data page exceed a coalesce threshold for the data page, applying the log records for the data page to a version of the data page and creating a new version that includes the changes indicated by the log records. An indication may be received to increase the coalesce threshold for a particular data page, delaying to a coalesce operation for the data page according to the increased coalesce threshold. The indication may be received from a storage engine that identifies a delay for the particular data page.
