Hi,
I'm trying to create a custom value generator for Basho Bench, but keep
getting this error:
escript: exception error: no match of right hand side value
{error,
{bad_return,
{{basho_bench_app,start,[normal,[]]},
I am trying to run a map-reduce job against all keys in a bucket. The job
is working fine on buckets with ~60,000 or less entries. However on buckets
with > 63,000 keys I get the following error every time:
Input:

There have been many improvements to MapReduce on the "tip" version, largely
thanks to some customers who want to crunch large datasets. In some test runs,
we have processed over 400K keys, so we know it's possible. Expect these
improvements in the 0.13 release (which will be pretty soon, if you
One problem with using the default number of partitions, which is 64, is that
many bucket/key pairs wind up hashing to the same few partitions. This has the
effect of concentrating the majority of the map function invocations onto a few
processes which winds up causing read function outs. These

I found that changing
erlang:apply(Module, Function, [Id] ++ Args);
