[ https://issues.apache.org/jira/browse/CASSANDRA-16573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17316667#comment-17316667 ]

-------------------------------------------------
[~paulo], should we add this to the GSoC tickets? Something in between for someone learning Cassandra

> Key: CASSANDRA-16573
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16573
> Project: Cassandra
> Issue Type: Bug
> Components: Documentation/Website
> Reporter: Brian Houser
> Priority: Normal
>
> The documentation on the website for the defaults of CQLSH appear to be incorrect and contain numerous errors (at least for the latest and greatest)
> For this page:
> [https://cassandra.apache.org/doc/latest/tools/cqlsh.html]
> {{MINBATCHSIZE}} is listed as defaulting to 2. Code says this is 10.
> https://github.com/apache/cassandra/blob/trunk/pylib/cqlshlib/copyutil.py#L355
> Chunksize says 1000, actually set to 5000.
> https://github.com/apache/cassandra/blob/trunk/pylib/cqlshlib/copyutil.py#L352
> NumProcessis is also off...
> "NUMPROCESSES
> The number of child worker processes to create for COPY tasks. Defaults to a max of 4 for COPY FROM and 16 for COPY TO. However, at most (num_cores - 1) processes will be created."
> Default is the number of cores -1 or 16 which ever is smaller, and you can set this value to anything. See the following code
> https://github.com/apache/cassandra/blob/trunk/pylib/cqlshlib/copyutil.py#L361
> https://github.com/apache/cassandra/blob/trunk/pylib/cqlshlib/copyutil.py#L407
