Description copied from class: JavaExecutionStrategy

Execute clustering to write inputRecords into new files as defined by rules in strategy parameters. The number of new file groups created is bounded by numOutputGroups. Note that commit is not done as part of strategy. commit is callers responsibility.

Specified by:

performClusteringWithRecordList in class JavaExecutionStrategy<T>

Parameters:

inputRecords - List of HoodieRecord.

numOutputGroups - Number of output file groups.

instantTime - Clustering (replace commit) instant time.

strategyParams - Strategy parameters containing columns to sort the data by when clustering.

schema - Schema of the data including metadata fields.

fileGroupIdList - File group id corresponding to each out group.

preserveHoodieMetadata - Whether to preserve commit metadata while clustering.

Returns:

List of WriteStatus.
