      Description

      unit-test-long failed on ! Ubuntu 18.04

      Host: ec2-3-90-83-115.compute-1.amazonaws.com
      Project: WiredTiger (develop)
      Commit: diff: WT-6175 Bound the amount of updates in cache (2nd attempt) (#5809)

      Adds a new "updates" target/trigger pair (to the existing "clean" and "dirty" limits) tracking the total amount of "small" objects in cache (generally inserts and updates). These default to a fraction of the dirty limits.

      • Switch to counting updates directly. On the plus side, this moves a field from WT_PAGE to WT_PAGE_MODIFY. On the negative, we're doing extra atomic increments on every allocation. | 17 Jun 20 02:12 UTC
