I was trying to incorporate WSO2 DSS 3.5.0 with Mongodb 3.2.1;
I found out that the functions exposed by the .dbs file are very limited compared to the mongo shell
for example:
the famous
db.collection.FindAndModify()
is not supported;
nested usage of mongodb shell command as following
db.collection.remove({_id: $BinData(3, #)}
can not be parsed
I googled around and found a ds-connector-mongodb(with mongo-java-driver-2.9.0, and jongo 0.3) on Github
I checkd the DSS 3.5.0 bundles under "/repository/components/plugins", and found "mongo-java-driver_3.0.0.wso2v2.jar" ...
I am totally confused about how mongodb is supported on WSO2 DSS 3.5
Had the "ds-connector-mongodb" been deprecated?
or had there it been a new structure/frame or what?
not to mention there were compatibility problems between the 2.x.x and 3.x.x of mongo-java-drive ...
please advice
thanks
For mongodb support the currently supported operations are available under MongoOperationLabels in [2] for other specific operations such as "db.collection.FindAndModify() custom operations will have to be written extending the current code base by extending[1]
[1]https://github.com/wso2/wso2-dss-connectors/blob/master/mongodb/src/main/java/org/wso2/dss/connectors/mongodb/MongoDBDataSource.java
[2] https://github.com/wso2/wso2-dss-connectors/blob/master/mongodb/src/main/java/org/wso2/dss/connectors/mongodb/MongoDBDSConstants.java
The currently available operations are as below
COUNT,
DROP,
FIND,
FIND_ONE,
INSERT,
REMOVE,
UPDATE
The documentation[3] explains how a data source can be created using the WSO2 Data Services Server. Hear please note that the Servers can be specified as a comma separated list of server hosts and ports as: "localhost" - "125.10.5.3, 125.10.5.4" - "192.168.3.1:27017, 192.168.3.2:27017"
The Auto Connect Retry is used to controls whether or not to connect. when the system retries to connect automatically.
You may also find [4] which is a sample that explains how operations such as createCollection can be used
