We often need to request what are the online redo log details, such as the number of groups and their respective sizes. It would be helpful going forward to log these details directly into the logs, perhaps as something like:

Redo Group #1 has 2 members at 200,000,000 bytes.
Redo Group #2 has 2 members at 200,000,000 bytes.
...

We either should consider to log these details during the Task start-up or we should consider logging these details at the start of the streaming phase where these details may have performance impact.
