In this timeout exception, we pass that 0 replicas responded. This is very confusing to someone looking at the client logs. I think we might need to throw a separate exception for contention or may be add a flag in the timeout exception. We have seen many people confused by this so I think we should fix it.

Ran some tests and tweaked the schema from the blogpost and things look better.
I do have some further questions/suggestions besides the better names.
- What is the point of batchcount? The point of a batch is to group the
inserts into a single statement for the server, so why would you send multiple
of these sequentially? Even though it's possible I can't think of a realistic
workload that would use it.
- I think it would be helpful to output some information on the partition sizes
and batch sizes for inserts to give people a sense of what their selected
values will do, like:
{code}
Global:
Partitions: Min of X, Max of Y
Rows per partition: Min of X, Max of Y
Per Batch:
Partitions: Min of X, Max of Y
Rows per partition: Min of X, Max of Y
{code}
Further stress improvements to generate more realistic workloads
Key: CASSANDRA-7519
URL: https://issues.apache.org/jira/browse/CASSANDRA-7519
Project: Cassandra
Issue Type: Improvement
Components: Tools
Reporter: Benedict
Assignee: Benedict
Priority: Minor
Labels: tools
Fix For: 2.1.1
We generally believe that the most common workload is for reads to
exponentially prefer most recently written data. However as stress currently
behaves we have two id generation modes: sequential and random (although
random can be distributed). I propose introducing a new mode which is
somewhat like sequential, except we essentially 'look back' from the current
id by some amount defined by a distribution. I may possibly make the position
only increment as it's first written to also, so that this mode can be run
from a clean slate with a mixed workload. This should allow is to generate
workloads that are more representative.
At the same time, I will introduce a timestamp value generator for primary
key columns that is strictly ascending, i.e. has some random component but is
based off of the actual system time (or some shared monotonically increasing
state) so that we can again generate a more realistic workload. This may be
challenging to tie in with the new procedurally generated partitions, but I'm
sure it can be done without too much difficulty.

[jira] [Commented] (CASSANDRA-7519) Further stress improvements to generate more realistic workloads
[ https://issues.apache.org/jira/browse/CASSANDRA-7519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=14108226#comment-14108226 ] Benedict commented on CASSANDRA-7519: - bq. What is the point of batchcount? The point of a batch is to group the inserts into a single statement for the server, so why would you send multiple of these sequentially? Even though it's possible I can't think of a realistic workload that would use it. The idea was to support benchmarking many inserts into a very wide row. However now that we support the revisit mechanism, this does seem superfluous. There is one slight potential reason to include it, which is that currently batches only support 5000 statements. Currently stress automatically splits into batches of this size, but perhaps we should error out at the start if it's possible to generate a batch larger than this, and support this option to permit users to split it up. Or, alternatively, we should drop this option and forbid batches larger than 5000 in size only if using LOGGED batches. Any of the above seem reasonable to me. bq, I think it would be helpful to output some information on the partition sizes and batch sizes for inserts to give people a sense of what their selected values will do, That does sound sensible, yes. I'll ad that. It seems that it might be worthwhile including an estimate of the size of data we've sent in the main stress output as well, as with a lot of randomly (esp. expontentially) generated data it could vary dramatically, so the current data might not be as useful. As it first appears. Separately, I think we should make a minor tweak and base the stderr calculation on partition count, not operation count.
