Hi,
Is this question the same like the previous one?
About your question this is the default cfg
(config/default-distributed-db-config.json):
{
"autoDeploy": true,
"hotAlignment": false,
"readQuorum": 1,
"writeQuorum": 2,
"failureAvailableNodesLessQuorum": false,
"readYourWrites": true,
"clusters": {
"internal": {
},
"index": {
},
"*": {
"servers" : [ "<NEW_NODE>" ]
}
}
}
As you can see al the clusters ("*") are replicated on each new servers. If
you have the class *Client* that works against 2 clusters *client_usa* and
*client_europe* you can do this:
{
"autoDeploy": true,
"hotAlignment": false,
"readQuorum": 1,
"writeQuorum": 2,
"failureAvailableNodesLessQuorum": false,
"readYourWrites": true,
"clusters": {
"internal": {
},
"index": {
},
"client_usa": {
"servers" : [ "usa" ]
}
"client_europe": {
"servers" : [ "europe" ]
}
"*": {
"servers" : [ "<NEW_NODE>" ]
}
}
}
So all the operation against client_usa will go to the server "usa". Every
time you execute a query against the class Client, a Map/Reduce like query
is executed against both servers.
