 ====== Implementations ======
-Distributed locking with Zoo-Keeper: https://dzone.com/articles/distributed-lock-using
+  * Distributed locking with Zoo-Keeper: https://dzone.com/articles/distributed-lock-using
-Hashicorp Consul: https://www.consul.io/docs/guides/semaphore.html
+  * Hashicorp Consul: https://www.consul.io/docs/guides/semaphore.html
-Relational database:
+  * Google Chubby
+  * Distributed locks with Redis: https://redis.io/topics/distlock
+    * Not recommended when lock should be used for guarantee correctness (http://martin.kleppmann.com/2016/02/08/how-to-do-distributed-locking.html)
+  * Relational database
+    * Fencing tokens
+    * Linearizable writes
+      * Writes should appear to be instantaneous. Once a write completes, all later reads should return the value of that write or the value of a later write. Once a read returns a particular value, all later reads should return that value or the value of a later write.
