Abstract
Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions according to review and approval workflows. The transaction exchange platform may receive transactions from origination sources, which may be added to the SDP as transaction objects. As the transactions are processed, the transactions may require access to a resource (e.g., a key value in a database). A microservice processing the transaction may request, from a locking microservice, a lock for the resource. The locking microservice may query a local cache to determine whether a lock exists for the resource. If the local cache determines that no lock exists for resource, the locking mechanism may employ a consensus protocol to obtain a lock for the resource from a plurality of clusters. If consensus is reached, a lock for the resource may be granted to the requesting microservice.
