When using the Java driver to create an index on an embedded MongoDB cluster with the following code:
MongoClient mongoClient = /* code to get the client */; MongoCollection items = mongoClient.getDatabase("todo").getCollection("items"); items.createIndex(Indexes.ascending("task"));
I get the following exception:
com.mongodb.MongoCommandException: Command failed with error 238: 'Not implemented for embedded: operator()' on server 127.0.0.1:27017. The full response is { "ok" : 0.0, "errmsg" : "Not implemented for embedded: operator()", "code" : 238, "codeName" : "NotImplemented" }
I'm able to replicate the error using the following runCommand
MongoDatabase todoDB = mongoClient.getDatabase("todo"); todoDB.runCommand(new Document() .append("createIndexes", "items") .append("indexes", Arrays.asList(new Document() .append("key", new Document() .append("task", 1)) .append("name", "task_1")) ));
Equivalent to
db.runCommand(
{
createIndexes: "items",
indexes: [
{
key: {
"task": 1,
},
name: "task_1"
}
]
}
)
It seems to be an issue with the creation of any index, and I suspect it's hitting this line of code, but I haven't confirmed this: https://github.com/mongodb/mongo/blob/master/src/mongo/client/embedded/replication_coordinator_embedded.cpp#L331
If it would help, here's the full stacktrace:
