    Description

      WiredTiger currently provides named snapshots, which allow applications to assign a name to a point in transaction time and perform reads as-of that time.

      The current implementation keeps all updates more recent than the oldest named snapshot pinned in cache, so it can easily cause the cache to become full of dirty pages that cannot be evicted. Find a solution so that ordinary reads and writes are not blocked by long-running readers.
