/**
 * Sometimes the amount of data exceeds buffers. In these cases we need to split the read data by some given range, usually the primary key.
 * I.e., the data is read in chunks where these chunks are split using the ID column range of values.
 *
 * With this hint one may configure the column to be used for splitting.
