>
> When a node in a job plan has a very long name (for example, a job that is
> reading from hundreds of different paths as a single input), an invalid dot
> file can be created.
> Based on simple testing with the dot command (version 2.32 on Mac OS X), it
> seems that the node name limit in a dot file is 3000 characters. However,
> even this length of node name leads to basically unreadable dot files, so
> there should be some kind of abbreviation done on long node names before
> writing out job plan dot files.
