[jira] [Comment Edited] (CASSANDRA-21444) Speed up nodetool documentation generation by producing all command help in a single jvm
[ https://issues.apache.org/jira/browse/CASSANDRA-21444?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18089893#comment-18089893 ]

I think this is such a nice improvement that it qualifies to be in cassandra-6.0 branch as well. It applies cleanly and is a net positive, I just don't see why we couldn't have it there too.

> Generating the nodetool AsciiDoc documentation is slow as the gen-nodetool-docs script uses the nodetool command-line wrapper to capture help text for eac command. Each invocation starts a brand-new jvm, so building the documentation incurs the jvm startup cost over a hundred times (100+ node tool commands).
> This makes the documentation build unnecessarily slow and ties it to the shell wrapper and its environment setup. The solution: Generate the raw {{nodetool help}} text for every command in a single jvm.
