[英]WSO2 DSS support for mongodb 3.x.x
I was trying to incorporate WSO2 DSS 3.5.0 with Mongodb 3.2.1; 我试图将WSO2 DSS 3.5.0与Mongodb 3.2.1合并;
I found out that the functions exposed by the .dbs file are very limited compared to the mongo shell 我发现与mongo shell相比,.dbs文件公开的功能非常有限
for example: 例如:
the famous 著名的
db.collection.FindAndModify()
is not supported; 不支持;
nested usage of mongodb shell command as following mongodb shell命令的嵌套用法如下
db.collection.remove({_id: $BinData(3, #)}
can not be parsed 无法解析
I googled around and found a ds-connector-mongodb (with mongo-java-driver-2.9.0, and jongo 0.3) on Github 我在Google上四处搜寻,并在Github上找到了ds-connector-mongodb (带有mongo-java-driver-2.9.0和jongo 0.3)
I checkd the DSS 3.5.0 bundles under "/repository/components/plugins", and found "mongo-java-driver_3.0.0.wso2v2.jar" ... 我在“ / repository / components / plugins”下检查了DSS 3.5.0捆绑软件,发现“ mongo-java-driver_3.0.0.wso2v2.jar” ...
I am totally confused about how mongodb is supported on WSO2 DSS 3.5 我对WSO2 DSS 3.5如何支持mongodb感到非常困惑
Had the "ds-connector-mongodb" been deprecated? “ ds-connector-mongodb”是否已被弃用? or had there it been a new structure/frame or what?
还是有一个新的结构/框架或什么?
not to mention there were compatibility problems between the 2.xx and 3.xx of mongo-java-drive ... 更不用说mongo-java-drive的2.xx和3.xx之间存在兼容性问题...
please advice thanks 请指教谢谢
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] 对于mongodb支持,当前支持的操作在[2]中的MongoOperationLabels下可用,用于其他特定操作,例如“ db.collection.FindAndModify(),必须编写自定义操作,方法是通过扩展[1]扩展当前代码库

The documentation[3] explains how a data source can be created using the WSO2 Data Services Server. 文档[3]解释了如何使用WSO2数据服务服务器创建数据源。 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"
请注意,可以将服务器指定为以逗号分隔的服务器主机和端口列表:“ 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. 自动连接重试用于控制是否连接。 when the system retries to connect automatically.
系统重试自动连接时。
