Abstract: The packer system includes a packer mandrel, an upper support or gage ring, a seal member, an upper slip device, an upper cone, a lower cone, a lower slip device, a setting sleeve, and a setting piston. The seal member has a run-in position and a set position. The set position seals against a borehole at a location in a borehole. The setting sleeve has a bypass position to transfer load of the setting piston away from the lower slip device and to the lower cone, the seal member, and the upper cone to set the seal member and upper slip device before the lower slip device. The setting sleeve has a released position to separate from the setting piston so that the load of the setting piston can finally be applied on the lower slip device for expansion of the lower slip device at the proper time and location.

Abstract: A serverless computing-based, continuous gateway watch of a data store for data change process is provided. The process includes the gateway interface of the computing environment receiving a watch request from a user system to monitor the data store for data change. Based on receiving the watch request, the gateway interface invokes a serverless setup service to establish a connection between the gateway interface and the data store of the computing environment to be monitored for data change. Based on receiving, at the gateway interface, a data change indication from the data store, the gateway interface invokes a serverless message process service to mutate the data change indication from the data store into a mutated data change message indicative of a data change at the data store for return to the user system pursuant to the watch request, with the serverless message process service terminating thereafter.
