Thanks [[email protected]].
But in the code there are these methods
{code}
static TestOptions calculateRowsAndSize(final TestOptions opts) {
int rowsPerGB = getRowsPerGB(opts);
if (opts.size != DEFAULT_OPTS.size) {
// total size in GB specified
opts.totalRows = (int) opts.size * rowsPerGB;
opts.perClientRunRows = opts.totalRows / opts.numClientThreads;
} else {
opts.totalRows = opts.perClientRunRows * opts.numClientThreads;
opts.size = opts.totalRows / rowsPerGB;
}
return opts;
}
static int getRowsPerGB(final TestOptions opts) {
return ONE_GB / ((opts.valueRandom? opts.valueSize/2: opts.valueSize) *
opts.getColumns());
}
{code}
So does this mean that with 50 threads the range is 50M rows (2nd option in
calculateRowsAndSize) or some other calculation which depends on the value size
* #columns(?)
Also, another question, in PE, when we run with
{code}
--columns=50 --valueSize=200
{code}
does this means the value is of size 200B or each column is of size 200B and
the value size is of size 50*200B(?)
I thought the first option was correct but from looking at the getRowsPerGB
method it seems the second one (50*200B) is the answer
