@vvysotskyi I did spot one [other recursive file listing](https://github.com/jnturton/drill/blob/65fb7ddc144ecae5330c9325af63010748f74cdf/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/metadata/Metadata.java#L376) that could possibly use the short cut in this PR if I propagate a `limit0` flag down to it. It appears to be invoked only if there are Parquet files present at the top level of the queried path which I don't think should be too common for big datasets since data files are generally only present at the leaves of the directory tree. So I thought I'd ask if you think it's worth trying to implement the single file short cut here too, or we just leave it alone? -- This is an automated message from the Apache Git Service.
