US 12,619,602 B2 · Propagating resource scaling information between source and target data stores of a materialized view

Abstract

A materialized view management service (MVMS) is capable of monitoring resource allocation changes of a source data object at a source data store and responsively generating resource change alerts to the owner of a target data object (the materialized view) in the target data store. Resource allocation changes may include autoscaling changes to the source data object's partition scheme, throughput limit, storage limit, and the like. The MVMS generates resource change alerts in response to these detected events and pushes the alerts to interested subscribers. Depending on the embodiment, the alerts may be pushed to human administrators, or the target data store itself, which may be configured to automatically adjust the resource allocation of the target data object to match the source data object. Advantageously, the disclosed alerts allow view owners to gain real time visibility of resource auto-scaling at the data source and appropriately react to such changes.

Dependent claims

A system, comprising:

at least one processor;
and
a memory, storing program instructions that when executed on or across the at least one processor, cause the at least one processor to:
create, in a target data store of a second type of database system, a materialized view of a source data object stored in a source data store of a first type of database system;
receive, via a first interface, resource metadata about the source data object from the source data store, wherein the resource metadata indicates a change to a resource allocation of the source data object;
determine, based at least in part on a view definition of the materialized view, to update a resource allocation of the materialized view to handle an amount of data from the source data store after the change to the resource allocation of the source data object;
and
generate, via a second interface, a resource change alert based at least in part on the change to the resource allocation of the source data object, wherein the resource change alert includes an instruction that specifies the update to a resource allocation of the materialized view in response to the change to the resource allocation of the source data object.

A method, comprising:

performing, by one or more processors and associated memory:
creating, in a target data store of a second type of database system, a materialized view of a source data object stored in a source data store of a first type of database system;
receiving, via a first interface, resource metadata about the source data object from the source data store, wherein the resource metadata indicates a change to a resource allocation of the source data object;
determining, based at least in part on a view definition of the materialized view, to update a resource allocation of the materialized view to handle an amount of data from the source data store after the change to the resource allocation of the source data object;
and
generating, via a second interface, a resource change alert based at least in part on the change to the resource allocation of the source data object, wherein the resource change alert includes an instruction that specifies the update to a resource allocation of the materialized view in response to the change to the resource allocation of the source data object.

3 more elements

One or more non-transitory computer-readable storage media storing program instructions that when executed on or across one or more computing devices cause the computing devices to:

create, in a target data store of a second type of database system, a materialized view of a source data object stored in a source data store of a first type of database system;
receive, via a first interface, resource metadata about the source data object from the source data store, wherein the resource metadata indicates a change to a resource allocation of the source data object;
determine, based at least in part on a view definition of the materialized view, to update a resource allocation of the materialized view to handle an amount of data from the source data store after the change to the resource allocation of the source data object;
and
generate, via a second interface, a resource change alert based at least in part on the change to the resource allocation of the source data object, wherein the resource change alert includes an instruction that specifies the update to a resource allocation of the materialized view in response to the change to the resource allocation of the source data object.
