US 2020/0349067 A1 · MEMORY MANAGEMENT FOR SERVERLESS DATABASES

Abstract

A solution is disclosed for memory management of serverless databases that includes: based at least on detecting a trigger event, determining whether memory is to be reclaimed; based at least on determining that memory is to be reclaimed, determining an amount of memory to be reclaimed; identifying memory to be reclaimed; and reclaiming the identified memory. Disclosed solutions are flexible, enabling customization of the aggressiveness and manner of memory reclamation. This permits users to specify a tailored balance point between performance and cost, for arrangements that bill users based on resource usage (e.g., memory consumed by a serverless database). In some examples, users specify a ramp-down parameter that is used to determine how much memory can be evicted in a particular reclamation event, time intervals (or another criteria) for triggering a reclamation event, and a definition for whether a cache is active.

Dependent claims

One or more computer storage devices having computer-executable instructions stored thereon for memory management of serverless databases, which, on execution by a computer, cause the computer to perform operations comprising:

detecting a trigger event for reclaiming memory from a serverless database instance, wherein the trigger event comprises at least one event selected from the list consisting of;
a timer event and a memory usage parameter exceeding a threshold;
receiving a selection defining at least a portion of a set of performance parameters;
based at least on detecting the trigger event, determining whether memory is to be reclaimed, wherein determining whether memory is to be reclaimed comprises measuring the set of performance parameters;
receiving a selection defining a ramp-down parameter;
based at least on determining that memory is to be reclaimed, determining an amount of memory to be reclaimed, wherein determining an amount of memory to be reclaimed comprises calculating the amount of memory to be reclaimed using the ramp-down parameter;
identifying memory to be reclaimed, wherein identifying memory to be reclaimed comprises identifying a memory eviction priority;
receiving a selection defining a memory reclamation policy;
and
reclaiming the identified memory according to the memory reclamation policy.
