#59132 adds the sql.txn_stats.sample_rate cluster setting. The default setting is 0, which means never sample stats. However, we're soon going to change the DB Console page to show these sampled execution stats, which means that this setting has to be nonzero to show interesting information.

This issue tracks quantifying the performance effect of turning this setting up to always sample and seeing if it is realistic to remove this setting at all. If not, we might want to have a low but nonzero sample rate to provide some interesting data.
