Added "spill" and "hashagg" sections in the override example file, with
some comments:
spill: {
# These options are common to all spilling operators.
# They can be overriden, per operator (but this is just for
# backward compatibility, and may be deprecated in the future)
directories : [ "/tmp/drill/spill" ],
fs : "file:///"
}
hashagg: {
# The partitions divide the work inside the hashagg, to ease
# handling spilling. This initial figure is tuned down when
# memory is limited.
# Setting this option to 1 disables spilling !
num_partitions: 32,
spill: {
# The 2 options below override the common ones
# they should be deprecated in the future
directories : [ "/tmp/drill/spill" ],
fs : "file:///"
}
},
