ULC log records

This row provides an average number of log records per transaction. It is useful in benchmarking or in controlled development environments to determine the number of log records written to ULCs per transaction.

Many transactions, such as those that affect several indexes or deferred updates or deletes, require several log records for a single data modification. Queries that modify a large number of rows use one or more records for each row.

If this data is unusual, study the data in the next section, Maximum ULC size and look at your application for long-running transactions and for transactions that modify large numbers of rows.
