A simple JobDivisionManager which builds divisions based on a preferred chunk size. If for instance there's a chunk size of 1000 records, and an incoming job has an expected row count of 30,000 records - then there will be 30 divisions made.

    public FixedChunkSizeJobDivisionManager(int chunkSize) {
        if (chunkSize <= 0) {
            throw new IllegalArgumentException("Chunk size must be a positive integer");
         = chunkSize;
    public int calculateDivisionCount(AnalysisJob masterJobint expectedRows) {
        final int chunkCount = (int) Math.ceil((1.0d * expectedRows / ));
        return chunkCount;
