pub fn scan_backlog(
directory: &Utf8Path,
pattern: &str,
) -> Result<Vec<ConsumerBacklog>>Expand description
Scan directory and report the backlog of each consumer relative to the
newest segment matching pattern. Consumers are discovered by their
.<checkpoint_name> files. Segment contents are never decompressed. Only
their directory listing and file metadata are read. A nonexistent directory
yields an empty report.
