Remote procedure calls that offload search pattern matching from clients to servers
A system enables client to convert a command, which specifies applying a search pattern to a data object that is stored by server, into a remote procedure call, which specifies applying the search pattern to the data object that is stored by server, and to use a network connection between client and server to send the remote procedure call to server, in response to receiving the command. The system reads the data object from server, in response to receiving the remote procedure call. The system generates a match result by applying the search pattern to the data object. The system uses the network connection between client and server to send the match result to client as a part of a response to the remote procedure call, thereby enabling client to convert the response to the remote procedure call into a response, which comprises the match result, to the command.
1. A system for remote procedure calls that offload search pattern matching from clients to servers, comprising:
one or more processors; and
a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to:
receive, by a client side module, a command specifying a search pattern, a data object stored by a server, and application of the search pattern to the data object;
convert, by the client side module, the command into a remote procedure call and use a network connection between the client and the server to send the remote procedure call to the server in response to receiving the command specifying application of the search pattern to the data object, wherein the remote procedure call specifies the search pattern, the data object, and application of the search pattern to the data object;
read, by a server side daemon, the data object specified in the remote procedure call from the server;
generate, by the server side daemon, a match result by applying the search pattern specified in the remote procedure call to the data object read by the server side daemon; and
use, by the server side daemon, the network connection between the client and the server to send the match result to the client as a part of a response to the remote procedure call, thereby enabling the client side module to convert the response to the remote procedure call into a response to the command, which comprises the match result.
2. The system of claim 1 , wherein enabling the client to convert the command into the remote procedure call and use the network connection to send the remote procedure call to the server comprises providing the client with the client-side module that converts the command into the remote procedure call and uses the network connection to send the remote procedure call to the server.
3. The system of claim 2 , wherein the client-side module is incorporated in a client-side component that offloads part of a deduplication process from a disk array to the client and/or the server.
4. The system of claim 1 , wherein the search pattern comprises a regular expression and the server comprises a network access server.
5. The system of claim 1 , wherein using the network connection between the client and the server to send the remote procedure call to the server comprises determining whether the client is already connected to the server, and creating the network connection between the client and the server in response to a determination that the client is not already connected to the server.
6. The system of claim 1 , wherein the server-side daemon is incorporated in a server-side component that offloads part of a deduplication process from a disk array to the client and/or the server.
7. A computer-implemented method for remote procedure calls that offload search pattern matching from clients to servers, comprising:
receiving, by a client side module, a command specifying a search pattern, a data object stored by a server, and application of the search pattern to the data object;
converting, by the client side module, the command into a remote procedure call and use a network connection between the client and the server to send the remote procedure call to the server in response to receiving the command specifying application of the search pattern to the data object, wherein the remote procedure call specifies the search pattern, the data object, and application of the search pattern to the data object;
reading, by a server side daemon, the data object specified in the remote procedure call from the server;
generating, by the server side daemon, a match result by applying the search pattern specified in the remote procedure call to the data object read by the server side daemon; and
using, by the server side daemon, the network connection between the client and the server to send the match result to the client as a part of a response to the remote procedure call, thereby enabling the client side module to convert the response to the remote procedure call into a response to the command, which comprises the match result.
8. The computer-implemented method of claim 7 , wherein enabling the client to convert the command into the remote procedure call and use the network connection to send the remote procedure call to the server comprises providing the client with the client-side module that converts the command into the remote procedure call and uses the network connection to send the remote procedure call to the server.
9. The computer-implemented method of claim 8 , wherein the client-side module is incorporated in a client-side component that offloads part of a deduplication process from a disk array to the client and/or the server.
10. The computer-implemented method of claim 7 , wherein the search pattern comprises a regular expression and the server comprises a network access server.
11. The computer-implemented method of claim 7 , wherein using the network connection between the client and the server to send the remote procedure call to the server comprises determining whether the client is already connected to the server, and creating the network connection between the client and the server in response to a determination that the client is not already connected to the server.
12. The method of claim 7 , wherein the server-side daemon is incorporated in a server-side component that offloads part of a deduplication process from a disk array to the client and/or the server.
13. A computer program product, comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein to be executed by one or more processors, the program code including instructions to:
receive, by a client side module, a command specifying a search pattern, a data object stored by a server, and application of the search pattern to the data object;
convert, by the client side module, the command into a remote procedure call and use a network connection between the client and the server to send the remote procedure call to the server in response to receiving the command specifying application of the search pattern to the data object, wherein the remote procedure call specifies the search pattern, the data object, and application of the search pattern to the data object;
read, by a server side daemon, the data object specified in the remote procedure call from the server;
generate, by the server side daemon, a match result by applying the search pattern specified in the remote procedure call to the data object read by the server side daemon; and
use, by the server side daemon, the network connection between the client and the server to send the match result to the client as a part of a response to the remote procedure call, thereby enabling the client side module to convert the response to the remote procedure call into a response to the command, which comprises the match result.
14. The computer program product of claim 13 , wherein enabling the client to convert the command into the remote procedure call and use the network connection to send the remote procedure call to the server comprises providing the client with the client-side module that converts the command into the remote procedure call and uses the network connection to send the remote procedure call to the server.
