Abstract
System(s) and method(s) facilitate improved performance for insert/update query requests in a database. A lazy updating based on delaying updates of newly inserted records combined with a master-staging partitioning scheme avoid deterioration of performance arising from updating indexes related to new records inserted in a database. Table partitioning as well as partitioning of indexes associated with the table allow new records to reside in manageable sections of memory for pre-configured periods of times prior to being updated. To avoid deterioration of performance associated with increasing size of table/index partitions, the size is maintained below specific thresholds that can be determined based on query workload and other historical data. Deployment of partitions among file systems and design of update delay times can further increase performance of lazy updating.
