MCK 1.7.0 Release Notes

New Features

• Added support for auto embeddings in MongoDB Community to automatically generate vector embeddings for the vector search data. This document can be followed for detailed documentation
• MongoDBSearch: Updated the default mongodb/mongodb-search image version to 0.60.1. This is the version MCK uses if .spec.version is not specified.

Bug Fixes

• Fix an issue to ensure that hosts are consistently removed from Ops Manager monitoring during AppDB scale-down events.
• Fixed an issue where monitoring agents would fail after disabling TLS on a MongoDB deployment.
• Persistent Volume Claim resize fix: Fixed an issue where the Operator ignored namespaces when listing PVCs, causing conflicts with resizing PVCs of the same name. Now, PVCs are filtered by both name and namespace for accurate resizing.
• Fixed a panic that occurred when the domain names for a horizon was empty. Now, if the domain names are not valid (RFC 1123), the validation will fail before reconciling.
• MongoDBMultiCluster, MongoDB: Fix an issue where the operator skipped host removal when an external domain was used, leaving monitoring hosts in Ops Manager even after workloads were correctly removed from the cluster.
• Fixed an issue where the Operator could crash when TLS certificates are configured using the certificatesSecretsPrefix field without additional TLS settings.

q: is it reasonable to make this assertion a bit stronger? I.e. is the count deterministic and the output of status_msg?

[viveksinghggits]

Yes, this is reasonable. The response of the returned data might change because of the algorithm that vector search uses, but we can make the document count in response deterministic by passing the number of documents that we want in response. I have done that.
Since the documents that returned in the response might change, I think it won't be a good idea to actually assert the returned data.

q: shouldn't we make the default timeout a bit higher? I see it is invoked with 60 seconds.

[viveksinghggits]

In most of the places when we wait for index to be ready, we just sleep for 60 seconds, but I have increased this to 90 seconds.
