Abstract

In one embodiment, a network file management system 120 may use a persistent metadata store 410 and an access control list 420 to facilitate a batch rollout. The network file management system 120 may maintain a content database 312. A network file management system 120 may store a metadata set for the content database 312 in a separate persistent metadata store 410.

Claims20

Dependent claims

A method for executing read operations in a network file management system, the method comprising:

receiving, from a client device, a request to perform a first read operation of a data file stored in a content database containing multiple data files;
responsive to the first read operation,
directing, at a load balancer, the received request to a first server configured to access the data files in the content database according to first configuration data corresponding to a first version of the network file management system, the first configuration data being stored in a first configuration database separate from the content database;
retrieving, with the first server, a copy of the requested data file from the content database according to the first configuration data;
and
transmitting, to the client device, the retrieved copy of the data file from the content database;
receiving, from the client device, another request to perform a second read operation of the data file stored in the same content database;
responsive to the received request, determining, at the load balancer, whether a version of the network file management system has changed from the first version to a second version;
in response to determining that the network file management system has changed from the first version to the second version, at the load balancer,
directing the received another request to a second server configured to access the data files in the content database according to second configuration data corresponding to the second version of the network file management system, the second configuration data being stored in a second configuration database separate from the content database and the first configuration database, wherein the first and second configuration databases are dual-mounted to the content database;
and
retrieving with the second server, another copy of the requested data file stored in the content database;
and
transmitting, to the client device, the retrieved another copy of the data file from the content database.

A method for executing read operations in a network file management system, the method comprising:

responsive to a user request to perform a read operation of a data file in a content database containing multiple data files, determining whether a version of the network file management system has changed from a first version to a second version;
in response to determining that the network file management system has not changed from the first version to the second version, directing the received request to a first server configured to access the data files in the content database according to first configuration data of the first version of the network file management system to process, store, present, and manage the data files in the content database;
and
in response to determining that the network file management system has changed from the first version to the second version, at the load balancer, directing the received another request to a second server configured to access the data files in the content database according to second configuration data of the second version of the network file management system to process, store, present, and manage the data files in the content database, wherein the first and second configuration data are respectively stored in a first and second configuration database that are both separate from and dual-mounted to the content database;
and
retrieving with the first or second server, a copy of the requested data file stored in the content database according to the first or second configuration data, respectively;
and
transmitting, to the client device, the retrieved copy of the data file from the content database.

5 more elements

A method for executing read operations in a network file management system having a load balancer, a content database storing multiple data files, and first and second servers configured to process, store, present, and manage the multiple data files in the content database according to first and second configuration data, respectively, wherein the method comprising:

responsive to a user request to perform a read operation of a data file in the content database, at the load balancer,
determining whether a build flag in an access control list of the content database containing a value indicating a first version or a second version of the network file management system;
in response to determining that the value of the build flag indicates the first version, directing the received request to the first server configured to access the data files in the content database according to the first configuration data stored in a first configuration database;
and
in response to determining that the value of the build flag indicates the second version, directing the received request to the second server configured to access the data files in the content database according to the second configuration data stored in a second configuration database, wherein first and second configuration databases are dual-mounted to the content database;
and
retrieving, with the first or second server, a copy of the requested data file stored in the content database according to the first or second configuration data, respectively;
and
transmitting, to the client device, the retrieved copy of the data file from the content database.
