  16. def splitToFitMaxRecordsAndClose(batch: ColumnarBatch, maxRecordsPerFile: Long, recordsInFile: Long): Array[SpillableColumnarBatch]

    Split a table into parts if recordsInFile + batch row count would go above maxRecordsPerFile and make the splits spillable.

    Split a table into parts if recordsInFile + batch row count would go above maxRecordsPerFile and make the splits spillable.

    The logic to find out what the splits should be is delegated to getSplitIndexes.

    The input batch is closed in case of error or in case we have to split it. It is not closed if it wasn't split.

    batch

    ColumnarBatch to split (and close)

    maxRecordsPerFile

    max rowcount per file

    recordsInFile

    row count in the file so far

    returns

    array of SpillableColumnarBatch splits
