Distributed key/value store system using asynchronous messaging systems

A non-transitory computer-readable storage medium storing instructions for updating a value in a distributed key/value store system, the instructions comprising instructions for:

• at a network communication component:
• receiving, from an instance of the distributed key value store system, a message indicating a key and corresponding value;
• and
• in response to receiving the message:
• storing the key and corresponding value in a database;
• and
• publishing an update indicating the key and corresponding value to a plurality of instances of the key/value store system.

A system for updating a value in a distributed key/value store system, the system comprising one or more instances of the distributed key/value store system and memory storing instructions that, when executed, cause the system to:

• at a network communication component:
• receive, from an instance of the distributed key value store system, a message indicating a key and corresponding value;
• and
• in response to receiving the message:
• store the key and corresponding value in a database;
• and
• publish an update indicating the key and corresponding value to a plurality of instances of the key/value store system.

A method for retrieving a value in a distributed key/value store system, comprising:

• at an instance of the distributed key/value store system:
• receiving a request to retrieve a value;
• and
• in response to receiving the request to retrieve the value:
• determining whether the value is stored in a local cache associated with the instance of the distributed key/value store system;
• in accordance with the determination that the value is stored in the local cache, retrieving the value from the local cache;
• and
• in accordance with the determination that the value is not stored in the local cache:
• sending a message to a network communication component of the distributed key/value store system, the message indicating a key corresponding to the requested value;
• and
• receiving, from the network communication component, a response including the requested value.

A method for securely publishing values via a distributed key/value store system, comprising:

• encrypting a data key and an authentication key;
• at a first instance of the distributed key/value store system:
• using the data key to encrypt a value;
• using the authentication key to compute a first hash of the encrypted value;
• and
• publishing the encrypted value, the first hash, and the encrypted keys, via an asynchronous messaging service, to a plurality of instances of the distributed key/value store system.

• encrypt a data key and an authentication key;
• at a first instance of the distributed key/value store system:
• use the data key to encrypt a value;
• use the authentication key to compute a first hash of the encrypted value;
• and
• publish the encrypted value, the first hash, and the encrypted keys, via an asynchronous messaging service, to a plurality of instances of the distributed key/value store system.
