Field Detail

MIN_MERGED_BATCH_SIZE

public static final int MIN_MERGED_BATCH_SIZE

Smallest allowed output batch size. The smallest output batch created even under constrained memory conditions.

MIN_SPILL_FILE_SIZE

public static final long MIN_SPILL_FILE_SIZE

In the bizarre case where the user gave us an unrealistically low spill file size, set a floor at some bare minimum size. (Note that, at this size, big queries will create a huge number of files, which is why the configuration default is one the order of hundreds of MB.)
