This patchset is a part of a bigger effort for bringing our
microbenchmarking tests from the source tree to be used for regression
testing purposes with CI.
Now, it is possible to export results of tests run into JSON format that
can be stored in ElasticSearch and compared among runs to detect
performance degradation should it happen.
Example of JSON output (formatted for readability):
{
"results" :
{
"parameters" :
{
"read" : "64",
"read,skip,test_run_count" : "64,256,1",
