  • Configuring replication across shards of scalable database tables for improved query performance
    Patent number: 12468730
    Abstract: Replication of a client-managed table may be configured across shards of system-managed tables in a database system for improved query performance. A client-managed table may be identified to replicate as a complete copy of the table respectively collocated with two or more shards of one or more other system-managed tables. The complete copy may be stored in respective storage volumes of the two or more shards of the one or more other system-managed tables. Metadata for performing access requests at a database system may be updated to identify the client-managed table as collocated with the two or more shards of the one or more other system-managed tables.

  • DYNAMICALLY SCALING A DISTRIBUTED DATABASE ACCORDING TO A CLUSTER-WIDE RESOURCE ALLOCATION
    Publication number: 20250173338
    Abstract: Dynamic scaling may be performed for a distributed database according to a cluster-wide resource allocation. Performance metrics for different query processing nodes of a distributed database system are obtained and evaluated to make scaling decisions for the database system. Scaling operations may include increasing or decreasing database capacity units allocated to a query processing node according to the cluster-wide allocation or adding a new query processing node to the cluster, the new node being allocated database capacity units from the cluster-wide allocation of database capacity units.

  • Shard management for scaling database tables
    Patent number: 12105692
    Abstract: Shard management may be implemented for scalable database tables. A table may be identified as aligned with another table of the database according to a common shard key across multiple shards that are mapped to respective storage volumes of a data store of the database according to a placement hierarchy. Different portions of the table may be stored across the shards as respective table slices with corresponding portions of the other table as respective other table slices with same values of the shard key. Metadata for performing access requests to the database may be updated to identify individual ones of the table slices stored with individual ones of the other table slices as respective table slice groups that are mapped to respective ones of the shards in the placement hierarchy.
