[jira] [Commented] (ARROW-15363) [C++] Add max length option to PrettyPrintOptions

["Joris Van den Bossche (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-15363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17478622#comment-17478622 ]

-----------------------------------------------

Another option to consider is to have a max length on the "scalar" level, instead of the array level (in practice, this might only be relevant/necessary for variable sized types, i.e. binary and string; I think all other non-nested types have a fixed / max length)

> Some pretty prints, especially for chunked or nested arrays, can be very long even with reasonable window settings. We should have a way to set some target maximum length to output.
> A half-measure was taken with ARROW-15329, which truncates the output of the pretty printing, but that doesn't handle string columns very well if those string values contain delimiters.
