Abstract
In one embodiment, a method includes determining a data node corresponding to a data record to be inserted/updated in an index structure of a record-oriented file system, creating a lock on a corresponding data node, splitting the corresponding data node sequentially into two data nodes and storing the data record in one of the two data nodes in response to the corresponding data node not having free space sufficient to store/update the data record, storing a high key of the first of the two data nodes to a parent index node, splitting the parent index node sequentially into two index nodes in response to the parent index node not having free space sufficient to store/update the high key of the first of the two data nodes, and storing the high key of the first of the two data nodes in one of the two index nodes.
