Rolling version update deployment utilizing dynamic node allocation

An apparatus for triggering rolling version updates by a configuration leader, comprising:

• a processor;
• a memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a version update for a set of workers managed by the configuration leader;
• determine a worker redundancy threshold that comprises a minimum number of workers managing task queues for a same tenant, wherein the same tenant comprises one or more users that share access to a common subset of data within a database managed by the configuration leader;
• select, by the configuration leader, from the set of workers, a subset of workers for updating, wherein the subset of workers is selected such that remaining workers of the set of workers maintain a level of worker redundancy greater than or equal to the worker redundancy threshold;
• transmit, to each worker of the subset of workers, an update message indicating the version update to perform;
• perform, at the selected subset of workers, the version update based at least in part on the update message;
• monitor, by the configuration leader, completion of the version update to receive, from each worker of the subset of workers, an update complete status of the version update based at least in part on each respective worker of the subset of workers performing the version update;
• update, by the configuration leader, version accounting over the selected subset of workers based at least in part on receiving, from each worker of the subset of workers, the update complete status;
• and
• repeat the selecting, transmitting, performing, monitoring and updating for at least one more worker of the set of workers.
