PigMix is a set of queries used test pig performance from release to release. There are queries that test latency (how long does it take to run this query?), and queries that test scalability (how many fields or records can pig handle before it fails?). In addition it includes a set of map reduce java programs to run equivalent map reduce jobs directly. These will be used to test the performance gap between direct use of map reduce and using pig. In Jun 2010, we release PigMix2, which include 5 more queries in addition to the original 12 queries into PigMix to measure the performance of new Pig features. We will publish the result of both PigMix and PigMix2.

Usage
To run PigMix
...
, run the following command from PIG_HOME:
Code Block |
---|
ant -Dharness.hadoop.home=$HADOOP_HOME pigmix-deploy (generate test dataset)
ant -Dharness.hadoop.home=$HADOOP_HOME pigmix (run the PigMix benchmark)
|
You can optionally set HADOOP_CONF_DIR before run.
If you want to change the default size of test dataset, change test/perf/pigmix/conf/config.sh.
Note the PigMix is checked in to Pig 0.12 and beyond. If you want to run it in earlier version of Pig, Please go to https://issues.apache.org/jira/browse/PIG-200 and use PIG-200-0.12.patch.
Runs
PigMix
The following table includes runs done of the pig mix. All of these runs have been done on a cluster with 26 slaves plus one machine acting as the name node and job tracker. The cluster was running hadoop version 0.18.1. (TODO: Need to get specific hardware info on those machines).
The tests were run against two versions of pig: top of trunk, and top of types branch both as of Nov 21 2008.
The tests were run three times for each version and the results averaged.

With this run we included a new measure, weighted average. Our previous multiplier that we have been publishing takes the total time of running all 12 Pig Latin scripts and compares it to the total time of running all 12 Java Map Reduce programs. This is a valid way to measure, as it shows the total amount of time to do all these operations on both platforms. But it has the drawback that it gives more weight to long running operations (such as joins and order bys) while masking the performance in faster operations such as group bys. The new "weighted average" adds up the multiplier for each Pig Latin script vs. Java program separately and then divides by 12, thus weighting each test equally. In past runs the weighted average had significantly lagged the overall average (for example, in the run above for August 27 it was 1.5 even though the total difference was 1.2). With this latest run it still lags some, but the gap has shrunk noticably.
