Method flush

crates/commitlog/src/lib.rs:290–296

Write all outstanding transaction records to disk. Note that this does **not** force the OS to sync the data to disk. Use [`Self::flush_and_sync`] or call [`Self::sync`] after this method to ensure all data is on disk. Returns the maximum transaction offset written to disk. The offset is `None` if the log is empty and no data was pending to be flushed. Repeatedly calling this method may return

        trace!("flush commitlog");
        inner.flush()?;

        Ok(inner.max_committed_offset())
