1. A method for managing entries into a clustered index, the method comprising: a computer handling, by one or more processors, one or more commands, wherein each command loads a dataset into a database; the computer receiving, by one or more processors, a first dataset to load into the database; responsive to determining a first storage size for the first dataset exceeds a storage size threshold value, the computer identifying, by one or more processors, the first dataset for indexing utilizing an optimization plan, wherein the optimization plan disables a parallel load process for loading the first dataset into a target index; the computer querying, by one or more processors, a user through a user interface on the computer, to determine to disable the parallel load process for loading the first dataset into the target index and allow for sequential loading of the first dataset; responsive to receiving a selection from the user to disable the parallel load process for loading the first dataset into a target index, the computer querying, by one or more processors, a database system catalog of the database for the target index, wherein the database system catalog contains a list of indices of the first dataset in the form of metadata; the computer disabling, by one or more processors, a parallel loading process for the first dataset; and the computer loading, by one or more processors, the first dataset into the target index as a single load process, wherein the dataset is sorted according to the target index.
