6. A computer-implemented method, comprising:
determining a first checkpoint descriptor for a first application at a dialog-driven application management service, wherein the first checkpoint descriptor includes a first rule for identifying application state information to be included in a checkpoint, and wherein an utterance of a client of the first application is transmitted to the dialog-driven application management service as a sequence of input blocks; generating, at the dialog-driven application management service, based at least in part on detecting that a checkpoint boundary criterion has been met with respect to the first application, a first checkpoint in accordance with the first rule, wherein the first checkpoint comprises one or more identifiers for respective input blocks obtained at the dialog-driven application management service from a particular client-side component of the dialog-driven application management service; obtaining a plurality of input blocks at the dialog-driven application management service subsequent to a connectivity failure and a re-establishment of connectivity between the particular client-side component and the dialog-driven application management service, wherein the plurality of input blocks comprises one or more retransmitted input blocks; and determining, at the dialog-driven application management service using the first checkpoint, at least one input block of the plurality of input blocks for which further processing is not to be performed. |
