A method and system for executing distributed locks in a locking system is disclosed. The system includes receiving a lock request including at least a lock name of a resource to place a lock on; determining a shard key at least based on the lock name and a prefix value, wherein the locking system includes a set of database instances, and wherein the prefix value is a number of database instances in the locking system; sending the lock request to at least two database instances in the set of database instances to place the lock in an entry pointed by the shard key; acknowledging the lock request when all of the at least two database instances acknowledge the lock request; and dismissing the lock request when at least one database instance of the at least two database instances cannot acknowledge the lock request.

Techniques for distributed locks

A method and system for providing consistency in read-after-write operations in a multi-replica relational database system (RDS) are provided. The method includes receiving a read transaction to read data from a database (DB) replica of the multi-replica RDS; obtaining counter values of DB replicas in the multi-replica RDS, a counter value of determines a current version of recent data stored in the respective DB replica; determining a write replica out of the DB replicas in the multi-replica RDS; determining if there is an available read replica, a read replica is a replica other than the determined write replica having counter value at least equals to a counter value of the write replica; and waiting, when there is no available read replica, a preconfigured time window to allow all replicas to synchronize with the write replica; and reading the data from a read replica when the preconfigured time window has elapsed.
