Does DocumentDB support mongo shell?-CodePudding

I am using AWS document db v4.0.0. It works fine with my application using MongoDB driver to connect. But when I try to use mongo shell it gives me some errors on basic query:

db.myCollection.find({})
Error: error: {
    "ok" : 0,
    "code" : 303,
    "errmsg" : "Feature not supported: 'causal consistency'",
    "operationTime" : Timestamp(1645150705, 1)
}

Does this mean DocumentDB is not compatible with mongo shell?

CodePudding user response：

Your code is missing the actual connection part, but make sure you have the TLS keys placed on the machine.

Your connection string should be something like this:

mongo --ssl host docdb-2020-02-08-14-15-11. cluster.region.docdb.amazonaws.com:27107 --sslCAFile rds-combined-ca-bundle.pem --username demoUser --password

There is actually a really good example/explanation in the official AWS Documentation

CodePudding user response：

Casual consistency isn't supported in DocumentDB. From your mongo shell you can run "db.getMongo().setCausalConsistency(false)" then re-run your find operation.
