Distributed stream-based database triggers

A database management method, comprising:

• associating a plurality of computing nodes, including a computing node, with a set of instructions to be performed in response to a request to store an item in a collection of items maintained by a database system;
• obtaining information associated with the request to store the item in the collection of items;
• in response to obtaining the information, causing the computing node to obtain the set of instructions based at least in part on resource utilization of the plurality of computing nodes;
• and
• causing the set of instructions to be performed by the computing node, wherein causing the computing node to perform the set of instructions at least in part balances workload distribution across the plurality of computing nodes.

A non-transitory computer-readable storage medium having stored thereon instructions that, upon execution by one or more computing devices, cause the one or more computing devices at least to:

• associate a plurality of computing nodes, including a computing node, with a set of instructions to be performed in response to a database system obtaining a request to store an item in a collection of items;
• in response to the request, cause the computing node to obtain the set of instructions based at least in part on resource utilization of the plurality of computing nodes;
• and
• cause the set of instructions to be performed by the computing node, wherein causing the computing node to perform the set of instructions at least in part supports equalization of workload distribution across the plurality of computing nodes.
