Maintaining components of networked nodes with distributed data dependencies

A first node device, comprising:

• a memory that stores computer executable components;
• a network interface that connects to a network of peer node devices;
• a drive storage device that stores node data in coordination with related data stored in a second node device selected from the peer node devices, the first node device and the second node device being in a neighborhood of node devices selected from the peer node devices;
• and
• a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
• an update receiving component to receive an update for a component of the first node device, wherein the first node device was selected to receive the update based on the second node device being determined not to have a dependency on the first device, that results in, when the first device is rendered unavailable for provision of access to data by the update, the second device is not rendered unavailable for provision of the access to the data, and
• an updating component to update the component of the first node device while the first node device is disabled from providing the node data.

A non-transitory machine-readable medium comprising executable instructions that, when executed by a processor of a first device, facilitate performance of operations, the operations comprising:

• identifying, in a group of dependent nodes of a cluster of nodes, a second device to be updated with an update, wherein the group of dependent nodes stores data linked across the group of dependent nodes;
• selecting, from the group of dependent nodes, a third device to provide data of the second device while the second device is updated with the update, wherein the third device was selected based on the third device being determined not to have a dependency on the second device, wherein, when the second device is rendered unavailable for provision of access to the data by the update, the third device is not rendered unavailable for provision of the access to the data;
• and
• updating the second device with the update.
