Ariel Weisberg commented on CASSANDRA-7933:
-------------------------------------------
Brought over from CASSANDRA-8597. Stress needs additional documentation to
introduce concepts and verbiage as well as common workflows. Most first time
users will not be familiar with C* terminology .
There are two dimensions data distribution and access distribution and knowing
all the knobs for describing data distribution (# partition, # cells/rows,
#size of cells) and access distribution (across partitions, across cells within
partitions, random vs sequential strides, # of rows/cells to select) would be
helpful. I think some times these parameters are linked as well. Understanding
data and access distribution is key to realistically simulating workloads.
A recipe of how you do a bulk load and then transition to some other mixed
read/write pattern with matching schema. A recipe for single column rows as
well as multi-column or very wide rows.
It's also worth mentioning in the distribution section that you can get the
tool to print a summary of distributions so you know what the parameters are
doing.
