US 11,960,487 B2 · Configuration-aware micro-database caches

Abstract

Methods and systems for using dispersed cached data stored in multiple database nodes for serving database access requests are described herein. Upon receiving a request for data from a requesting device, a first application server determines whether the requested data is stored in a local cache memory. If it is determined that the requested data is not stored in the local cache memory, without accessing a local, first database, the first application server determines that the requested data is stored in a cache memory of a second application server, wherein the second application server stores at least a portion of the data from a second database in its cache memory. The first application server retrieves the requested data from the cache memory of the second application server and provides the retrieved data to the requesting device.

Dependent claims

A system comprising:

one or more hardware processors;
and
one or more machine-readable storage media having instructions stored thereon that, in response to being executed by the one or more hardware processors, cause the system to perform operations comprising:
receiving, by a first computer node and from a user device, a request for information that is stored in a distributed database distributed across a plurality of computer nodes comprising the first computer node, wherein the first computer node comprises (i) a first database storing data associated with the distributed database and (ii) a first cache memory;
determining that the information is not stored in the first cache memory;
in response to determining that the information is not stored in the first cache memory and without accessing the first database, determining, based on a cache index, that the information is stored in a second cache memory of a second computer node from the plurality of computer nodes;
retrieving the information from the second cache memory of the second computer node via a computer network;
and
transmitting the information to the user device.

6 more elements

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

receiving, from a user device, a request for information that is stored in a distributed database distributed across a plurality of computer nodes comprising a first computer node, wherein the first computer node comprises (i) a first database storing data associated with the distributed database and (ii) a first cache memory;
in response to determining that the information is not stored in the first cache memory and without accessing the first database, determining, based on accessing a cache index, that the information is stored in a second cache memory of a second computer node from the plurality of computer nodes, wherein the second computer node is different from the first computer node;
in response to determining that the second computer node is available, retrieving the information from the second cache memory of the second computer node;
and
transmitting the information to the user device.
