v3.5.9

Compare Source

The MongoDB Node.js team is pleased to announce version 3.5.9 of the driver

Release Highlights

Use duration of handshake if no previous roundTripTime exists

The default roundTripTime of a ServerDescription is -1, which means if that value is used we can potentially calculate a negative roundTripTime. Instead, if no previous roundTripTime exists, we use the duration of the initial handshake.

the options [maxIdleTimeMS] is not supported

A number of new options were added when the CMAP compliant connection pool was introduced in 3.5.x. Unfortunately, these options were not documented properly. Now they are mentioned in the MongoClient documentation, with a notice that they are only supported with the unified topology.

TypeError: Reduce of empty array with no initial value

A fix in 3.5.8 which ensured proper filtering of servers during server selection exposed an issue in max staleness calculations when the topology type is ReplicaSetNoPrimary and no servers are currently known. In order to estimate an upper bound of max staleness when there is no primary, the most stale known server is known to compare the others to - if there are no known servers, you can't reduce the array!

Server monitoring is prevented under heavy request load

In certain very high load fail-over scenarios the driver is unable to reschedule a monitoring check in order to update its view of the topology for retryability. This would result in a high number of failed operations, as they were unable to determine a new viable server.

Documentation

Reference: http://mongodb.github.io/node-mongodb-native/3.5/
API: http://mongodb.github.io/node-mongodb-native/3.5/api/
Changelog: https://github.com/mongodb/node-mongodb-native/blob/3.5/HISTORY.md

We invite you to try the driver immediately, and report any issues to the NODE project.

Thanks very much to all the community members who contributed to this release!
