Database Administrator's Guide
There are two parameters that control the manner in which the compression is applied to log entries.
- The first is a size threshold:
If the variable region is less than this threshold, no compression is attempted.
- The second is a compression factor expressed as a percent:
If the compression does not fit in a buffer of size (<factor> * input_size / 100), then no compression takes place.
Snapshot statistics include compression results.
Note: Log compression is not currently supported.
