Data layer service availability

摘要

Disclosed are various embodiments for a token management application. A data block tokenization call to a data layer service fails when a data store is unavailable. The token management application issues a temporary data token to the service calling the data layer service. The token management application completes the data block tokenization call on behalf of the service to obtain a valid data token. The valid data token is then communicated to services having the temporary data token.

主权项

1. A non-transitory computer-readable medium embodying a program executable in at least one computing device, comprising:
code that determines when at least one data store is unavailable during a communication of a data block tokenization call from one of a plurality of services to a data layer service facilitating access to the unavailable at least one data store; code that generates a temporary token responsive to the determination that the at least one data store is unavailable; code that communicates the temporary token to the one of the services, wherein the temporary token is capable of being passed to other ones of the services; code that repeatedly queries the data layer service with the data block tokenization call until a successful query is performed after the at least one data store is available; code that obtains a valid token from the data layer service responsive to the successful query; code that facilitates a communication of the valid token to at least one of the services having the temporary token; and wherein the one of the services is associated with at least one dependent service, and the temporary token facilitates an operation of the at least one dependent service.
