  • Invoke SeriesSplitter and the subsequent function in separate SQL-MapReduce calls (as in the first choice in Example 2: Using SeriesSplitter with Interpolator), rather than using SeriesSplitter in the ON clause of the subsequent function (as in the second choice in Example 2: Using SeriesSplitter with Interpolator).
  • Adjust these arguments as follows:
    • DuplicateRowsCount: as low as possible
    • SplitCount: a smaller multiple (for example, 1) of the number of vworkers in the cluster
    • RowsPerSplit: as high as possible (you want the resulting number of splits to be a smaller multiple of the number of vworkers in the cluster)
    • Accumulate: specify as few columns as possible
    • DuplicateColumn: omit this argument
    • PartialSplitID: 'true'
    • ReturnStatsTable: 'true'
