             Summary: The description of SplunkPushDownRule doesn't match expression check in RelOptRule
                 Key: CALCITE-3099
                 URL: https://issues.apache.org/jira/browse/CALCITE-3099
             Project: Calcite
          Issue Type: Bug
          Components: splunk
    Affects Versions: 1.19.0
            Reporter: Shawn Chen
            Assignee: Shawn Chen


Some SplunkPushDownRule instance has a description that contains spaces, for example:

The description of _*PROJECT_ON_FILTER*_ is "proj on filter on proj", which doesn't match the expression check in RelOptRule:
{code:java}
if (!description.matches("[A-Za-z][-A-Za-z0-9_.():]*")) {
      throw new RuntimeException("Rule description '" + description
          + "' is not valid");
    }
{code}
The constructor of SplunkPushDownRule also contains spaces when invoking super():
{code:java}
  /** Creates a SplunkPushDownRule. */
  protected SplunkPushDownRule(RelOptRuleOperand rule,
      RelBuilderFactory relBuilderFactory, String id) {
    super(rule, relBuilderFactory, "SplunkPushDownRule: " + id);
  }
{code}
