Workload management using blockchain-based transaction deferrals

Abstract

A determination is made that a request associated with an application is a candidate for blockchain-based deferral. An insertion of a record representing at least the request at a blockchain is initiated. One or more records representing the request are accessed to perform an operation indicated in the request.

 examine a history of earlier transactions directed to other items of the first category; and 
 determine, based at least in part on examination of the history of earlier transactions, that at least a portion of processing of the first transaction is a candidate for blockchain-based deferral. 
   
     
     
         29 . The system as recited in  claim 28 , wherein the one or more computing devices include further instructions that upon execution on or across the one or more computing devices further cause the one or more computing devices to:
 cause a first record representing the portion of processing of the first transaction to be inserted into a blockchain; and   cause an indication that the portion of processing has succeeded to be provided to a submitter of the request prior to completion of implementation of the portion of processing.   
     
     
         30 . The system as recited in  claim 28 , wherein the one or more computing devices include further instructions that upon execution on or across the one or more computing devices further cause the one or more computing devices to:
 provide an indication, to a submitter of the request, that the portion of processing has been deferred.   
     
     
         31 . The system as recited in  claim 28 , wherein the one or more computing devices include further instructions that upon execution on or across the one or more computing devices further cause the one or more computing devices to:
 select, from among a plurality of resource groups, a particular resource group at which a first record representing the portion of processing of the first transaction is to be stored in a blockchain, wherein selection of the particular resource group is based at least in part on an estimate of a cost associated with storing the first record at the particular resource group.   
     
     
         32 . The system as recited in  claim 28 , wherein the one or more computing devices include further instructions that upon execution on or across the one or more computing devices further cause the one or more computing devices to:
 obtain a score pertaining to the first transaction from one or more of: (a) a machine learning model or (b) a rule processing system, wherein the portion of processing of the first transaction is a determined as a candidate for blockchain-based deferral based at least in part on the score.
