  • Systems and methods for synchronizing between a source database cluster and a destination database cluster
    Patent number: 12423199
    Abstract: In some embodiments, a database cluster to cluster synchronization system may include multiple replicators coupled to a source database cluster and a destination database cluster, where the source and destination cluster may be shard clusters. Each of the multiple replicators may correspond to a respective subset of the source database cluster and configured to monitor changes of data on the respective subset of the source database cluster and translate the changes of data to one or more database operations to be performed on the destination cluster. The changes of data on the source database may be contained in respective change streams associated with each of the replicators.

  • SYSTEMS AND METHODS FOR MANAGING SHARDED DATA
    Publication number: 20240427804
    Abstract: A database system may comprise one or more nodes, where each node is embedded with functionality of each of a shard server configured for storing, retrieving, managing, and/or updating data; a shard routing process; and metadata management. A single node running these functionalities allows a database system to provide improved sharding functionality. Nodes may run on a same hardware profile. Database systems described herein may provide enhanced scalability and may appropriately scale without any input on the part of users.
