[jira] [Created] (SPARK-26191) Control number of truncated fields

Maxim Gekk created SPARK-26191:
----------------------------------

             Summary: Control number of truncated fields
                 Key: SPARK-26191
                 URL: https://issues.apache.org/jira/browse/SPARK-26191
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Maxim Gekk


Currently, the threshold for truncated fields converted to string can be controlled via global SQL config. Need to add the maxFields parameter to all functions/methods that potentially could produce truncated string from a sequence of fields.

One of use cases is toFile. This method aims to output not truncated plans. For now users has to set global config to flush whole plans.
