  • Publication number: 20240070193
    Abstract: Implementations relate to maintaining metadata, of a client device, stored on a remote computing device, to reduce overall network utilization and/or latency in responding to automated assistant requests received at the client device. The metadata of a client device is identified and provided to a remote computing device with a request that requires additional processing by the remote computing device. Current metadata is compared to previously provided metadata that was provided to the remote computing device with a previous request and one or more operations are generated based on the difference between the current metadata and the previous metadata. The remote computing device executes the one or more operations on a remote version of the metadata to generate a new remote version of the metadata of the client device. The remote computing device further processes the request with the new remote version of the metadata.
