Detailed Description
Spiel write lock context. Intended for taking write lock along transaction commission. When obtaining write lock, all read locks are revoked across entire cluster. Later read locks become obtainable only when write lock appears released explicitly.
- Note
- Write lock is held exclusively and cannot be revoked by RM. Only explicit lock cancellation is possible.
