Hi Luca,
I have done the changes in default-distributed-db-config.json (as mentioned
in the orientdb manual), then started orientdb instances (node1, node2,
node3) and created a class (actionevent). OrientDB versions tried with are
2.1.16 community & enterprise editions.
Please do find the config below
*{*
* "autoDeploy": true,*
* "hotAlignment": false,*
* "executionMode": "undefined",*
* "readQuorum": 1,*
* "writeQuorum": 2,*
* "failureAvailableNodesLessQuorum": false,*
* "readYourWrites": true,*
* "servers": {*
* "*": "master"*
* },*
* "clusters": {*
* "internal": {*
* },*
* "index": {*
* },*
* "actionevent_node1": {*
* "servers" : [ "node1", "node2", "node3" ]*
* },*
* "actionevent_node2": {*
* "servers" : [ "node1", "node2" ]*
* },*
* "actionevent_node3": {*
* "servers" : [ "node3" ]*
* },*
* "*": {*
* "servers": [ "<NEW_NODE>" ]*
* }*
* }*
*}*
Ideally, as per the default-distributed-db-config.json configuration
actionevent_node1 cluster need to be placed at all the three nodes (node1,
node2,node3), actionevent_node2 at node1 & node2 , actionevent_node3 at
node3.
But, i could not see that the clusters are getting created at desired
servers as mentioned in the config file.
Can you please help me out in resolving the issue?
