To use the MongoDB connector with a replica set, you must set the value of the mongodb.connection.string property in the connector configuration to the replica set connection string.When the connector is ready to begin capturing changes from a MongoDB change stream, it starts a connection task.The connection task then uses the specified connection string to establish a connection to an available replica set member.
The mongodb.connection.string property replaces the removed mongodb.hosts property that was used to provide earlier versions of the connector with the host address of the configuration server replica.In the current release, use mongodb.connection.string to provide the connector with the addresses of MongoDB routers, also known as mongos.
For connectors that capture changes from a sharded MongoDB cluster, and for which the mongodb.connection.mode property is set to replica_set, you must grant the user permission to read the config.shards system collection.
Specifies a connection string that the connector uses to connect to a MongoDB replica set.This property replaces the mongodb.hosts property that was available in previous versions of the MongoDB connector.
Connectors that capture changes from a sharded MongoDB cluster use this connection string only during the initial shard discovery process when mongodb.connection.mode is set to replica_set.After the initial discovery process, connection strings are generated for each individual shard.
A full Java class name that is an implementation of the io.debezium.connector.mongodb.connection.MongoDbAuthProvider interface.This class handles setting the credentials on the MongoDB connection (called on each app boot).Default behavior uses the mongodb.user, mongodb.password, and mongodb.authsource properties according to each of their documentation,but other implementations may use them differently or ignore them altogether.Note that any setting in mongodb.connection.string will override settings set by this class
When using default mongodb.authentication.class:Database (authentication source) containing MongoDB credentials. This is required only when MongoDB is configured to use authentication with another authentication database than admin.
This property has an effect only when the connector is connected to a sharded MongoDB cluster and the mongodb.connection.mode property is set to replica_set.When the mongodb.connection.mode is set to sharded, or if the connector is connected to an unsharded MongoDB replica set deployment, the connector ignores this setting, and defaults to using only a single task.
Applications using MongoDB must be very carefully while updating. An update caused data loss: scenario here is UPDATE of a document.I used MongoDB 2.4 for this and ran the example given at -a-simple-todo-application-using-javafx-java-and-mongodb-part-2/It is a simple MongoDB Java driver app but on UPDATE of document it (mongoDB) (maybe its the java driver) silently updates your document with a empty document!

Since this article is 2.5 years old and the search in google mongodb step down data loss' returns you as the 5th result would you mind either A posting a notice about how 2.6 (or 3 for that matter) handles this scenario?
To connect to a MongoDB database, select Add Connection and enter the connection details for the database then Connect, the default is a local MongoDB server at mongodb://127.0.0.1:27017. You can also enter a connection string, click the "connect with a connection string" link and paste the connection string.
Quarkus supports a feature called Dev Services that allows you to create various datasources without any config. In the case of MongoDB this support extends to the default MongoDB connection.What that means practically, is that if you have not configured quarkus.mongodb.connection-string, Quarkus will automatically start a MongoDB container when running tests or in dev mode,and automatically configure the connection.
When using multiple clients, each MongoClient, you can select the client to inject using the io.quarkus.mongodb.MongoClientName qualifier.Using the above properties to configure three different clients, you can also inject each one as follows:
If you are using the quarkus-micrometer or quarkus-smallrye-metrics extension, quarkus-mongodb-client can provide metrics about the connection pools.This behavior must first be enabled by setting the quarkus.mongodb.metrics.enabled property to true in your application.properties.
If you need to customize the Mongo client configuration programmatically, you need to implement the io.quarkus.mongodb.runtime.MongoClientCustomizer interface and expose it as a CDI application scoped bean:
host is the only required part of the URI. It identifies a single host name for which SRV records are looked up from a Domain Name Server after prefixing the host name with "_mongodb._tcp". The host/port for each SRV record becomes the seed list used to connect, as if each one were provided as host/port pair in a URI using the normal mongodb protocol.
?options are connection options. Note that if database is absent there is still a / required between the last host and the ? introducing the options. Options are name=value pairs and the pairs are separated by "&". Additionally with the mongodb+srv protocol, TXT records are looked up from a Domain Name Server for the given host, and the text value of each one is prepended to any options on the URI itself. Because the last specified value for any option wins, that means that options provided on the URI will override any that are provided via TXT records.
This package lets you connect to MongoDB servers andupdate/query their data. Please see the example inDatabase.MongoDB and the tutorial from the homepage. Forinformation about MongoDB itself, see www.mongodb.org.

The recommended way to get started using the MongoDB Go driver is by using Go modules to install the dependency inyour project. This can be done either by importing packages from go.mongodb.org/mongo-driver and having the buildstep install the dependency or by explicitly running
