SessionOptions()¶

The options for a session in mongosh. To access the SessionOptions object, use the Session.getOptions() method.

The session options available are:

Option	Description
`causalConsistency`	Boolean. Enables or disables causal consistency for the session. You can explicitly set the option when you start a session manually: `Session = db.getMongo().startSession( { causalConsistency: true } )`
`readConcern`	Document. Specifies the read concern. In `mongosh`, you can set the option when you run `Mongo.startSession()`. You can also access the `readConcern` option via the following methods: `Session.getOptions().getReadConcern()` `Session.getOptions().setReadConcern(<document>)`
`readPreference`	Document. Specifies the read preference. In `mongosh`, you can set the option when you run `Mongo.startSession()`. You can also access the `readPreference` option via the following methods: `Session.getOptions().getReadPreference()` `Session.getOptions().setReadPreference({ mode: <string>, tags: <array>})`
`retryWrites`	Boolean. Enables or disables the ability to retry writes upon encountering transient network errors, such as during failovers. To enable retry writes, start `mongosh` with the `--retryWrites` option. You can view whether `retryWrites` is enabled for a session via the following method: `Session.getOptions().shouldRetryWrites()`
`writeConcern`	Document. Specifies the write concern. In `mongosh`, you can set the options when you run `Mongo.startSession()`. You can also access the `writeConcern` option via the following methods: `Session.getOptions().getWriteConcern()` `Session.getOptions().setWriteConcern(<document>)`

Verify which options are enabled for the session by running Session.getOptions().
