我可以使用副本集名称通过mongo-connector连接

Question

I would like to know, is there a way we can replicate from one mongo replica set to another via mongo-connector? As per mongo documentation we can connect two mongo instances via mongo-connector by using a command as in the example below, but I would like to pass replica set name or use a configuration file instead of passing server:port name in command line.

Mongo Connector can replicate from one MongoDB replica set or sharded cluster to another using the Mongo DocManager. The most basic usage is like the following:

mongo-connector -m localhost:27017 -t localhost:37017 -d mongo_doc_manager

I also tried config.json option by creating below config.json file but it has failed.

{
    "__comment__": "Configuration options starting with '__' are disabled",
    "__comment__": "To enable them, remove the preceding '__'",

    "mainAddress": "localhost:27017",
    "oplogFile": "C:\Dev\mongodb\mongo-connector\oplog.timestamp",
    "verbosity": 2,
    "continueOnError": false,

    "logging": {
        "type": "file",
        "filename": "C:\Dev\mongodb\mongo-connector\mongo-connector.log",
        "__rotationWhen": "D",
        "__rotationInterval": 1,
        "__rotationBackups": 10,
        "__type": "syslog"        
    },

    "docManagers": [
        {
            "docManager": "mongo_doc_manager",
            "targetURL": "localhost:37010",
            "__autoCommitInterval": null
        }
    ]
}

Answer 1

yes its possible to connect to a replica set or a shard server using mongo connector.

 {
mongo-connector -m <mongodb server hostname>:<replica set port> \
            -t <replication endpoint URL, e.g. http://localhost:8983/solr> \
            -d <name of doc manager, e.g., solr_doc_manager>
}

you can also also pass a connection string to the mongo-connector such as

{
mongo connector -m mongodb://db1.example.net,db2.example.net:2500/?replicaSet=test&connectTimeoutMS=300000

}

to specify specifc config files you can use

{ mongo-connector -c config.json } 

where config.json is your config file.

I'm able to resolve my issue by entering backslash '\\' for my windows directory path.Here is my updated config file for reference. Thanks to ShaneHarvey Not able to use Configuration file for connecting to mongo-connector

{
    "__comment__": "Configuration options starting with '__' are disabled",
    "__comment__": "To enable them, remove the preceding '__'",

    "mainAddress": "localhost:27017",
    "oplogFile": "C:\\Dev\\mongodb\\mongo-connector\\oplog.timestamp",
    "noDump": false,
    "batchSize": -1,
    "verbosity": 2,
    "continueOnError": false,

    "logging": {
        "type": "file",
        "filename": "C:\\Dev\\mongodb\\mongo-connector\\mongo-connector.log",
        "__format": "%(asctime)s [%(levelname)s] %(name)s:%(lineno)d - %(message)s",
        "__rotationWhen": "D",
        "__rotationInterval": 1,
        "__rotationBackups": 10,
        "__type": "syslog",
        "__host": "localhost:27017"        
    },  


    "docManagers": [
        {
            "docManager": "mongo_doc_manager",
            "targetURL": "localhost:37017",
            "__autoCommitInterval": null
        }
    ]
}
