Method and system for dynamic distributed data caching
A method and system for dynamic distributed data caching includes providing a cache community of peer members and a master member. A master member volunteers to leave the cache community upon which decision a peer member is selected to become the new master member. Each peer member has an associated first content portion indicating content to be cached by the respective peer. A client may be allowed to join the cache community. A peer list associated with the cache community is updated to include the client. The peer list indicates the peers in the cache community. A respective second content portion is associated with each peer based on the addition of the client.
1. A method for dynamic distributed data caching, comprising:
establishing a cache community for data storage, the cache community including a master member;
determining that the master member is to voluntarily leave the cache community;
determining whether the cache community includes other peer members;
selecting a peer member to become a new master of the cache community in response to the cache community including other peer members;
sending a nominate master message to the peer member selected to be the new master of the cache community.
2. The method of claim 1 , further comprising:
receiving a response to the nominate master message from the peer member;
shutting down the master member from the cache community.
3. The method of claim 1 , further comprising:
determining that a response to the nominate master message has not been received from the peer member;
selecting a new peer member to become the new master of the cache community.
4. The method of claim 1 , further comprising:
updating a peer list for the cache community by removing the master member from the peer list.
5. The method of claim 1 , further comprising:
sending a remove master request in response to the cache community not including any other peer members.
6. The method of claim 1 , wherein the peer member is selected to be the new master member based on either bandwidth availability or processing capability.
7. A computer readable storage medium including executable code for dynamic distributed data caching, the executable code operable to:
establish a cache community for data storage, the cache community including a master member;
determine that the master member is to voluntarily leave the cache community;
determine whether the cache community includes other peer members;
select a peer member to become a new master of the cache community in response to the cache community including other peer members;
send a nominate master message to the peer member selected to be the new master of the cache community.
8. The computer readable storage medium of claim 7 , wherein the executable code is further operable to:
receive a response to the nominate master message from the peer member;
shut down the master member from the cache community.
9. The computer readable storage medium of claim 7 , wherein the executable code is further operable to:
determine that a response to the nominate master message has not been received from the peer member;
select a new peer member to become the new master of the cache community.
10. The computer readable storage medium of claim 7 , wherein the executable code is further operable to:
update a peer list for the cache community by removing the master member from the peer list.
11. The computer readable storage medium of claim 7 , wherein the executable code is further operable to:
send a remove master request in response to the cache community not including any other peer members.
12. The computer readable storage medium of claim 7 , wherein the executable code is further operable to:
select the peer member be the new master member based on either bandwidth availability or processing capability.
13. A system for dynamic distributed data caching, comprising:
means for establishing a cache community for data storage, the cache community including a master member;
means for determining that the master member is to voluntarily leave the cache community;
means for determining whether the cache community includes other peer members;
means for selecting a peer member to become a new master of the cache community in response to the cache community including other peer members;
means for sending a nominate master message to the peer member selected to be the new master of the cache community.
14. The system of claim 13 , further comprising:
means for receiving a response to the nominate master message from the peer member;
means for shutting down the master member from the cache community.
15. The system of claim 13 , further comprising:
means for determining that a response to the nominate master message has not been received from the peer member;
means for selecting a new peer member to become the new master of the cache community.
16. The system of claim 13 , further comprising:
means for updating a peer list for the cache community by removing the master member from the peer list.
17. The system of claim 13 , further comprising:
means for sending a remove master request in response to the cache community not including any other peer members.
18. The system of claim 13 , wherein the peer member is selected to be the new master member based on either bandwidth availability or processing capability.
