Hi @Bivit ,

Welcome to Microsoft Q&A platform and thanks for using Azure Services.

As I understand your ask, some data in Cosmos DB Gremlin API got deleted.

Could you please let us know if your subscription is moved to another tenant recently?
Additionally, if you could please share more relevant details which could help us in troubleshooting.

Thanks for your patience.

I did not do any changes in the subscription for more than one year.

What details are relevant to you for troubleshooting?

Hello!

Anyone that helps people here or is Microsoft eager to show other how bad their products are?

Hi @Bivit ,

Thanks for your patience.

Data disappearance could be caused by TTL(Time to Live).

With Time to Live or TTL, Azure Cosmos DB provides the ability to delete items automatically from a container after a certain time period.

Could you please check if TTL is configured on the graph.

You can check whether this is set on the graph in the Azure Portal. If enabled at a graph level, you can also query whether items in the graph have TTL set. Example here: access-system-properties-gremlin

Reference link: time-to-live

Hope this helps. Do let us know if you have further queries.

Answer is not accepted since TTL is off by default an I ddid not changed any default settings. I also double checked the TTL settings now and it is off.

There are three vertices in the graph that persist all the time but rest of the data gets delete slowly not all at once.

Can backup rules cause something like this?

Ok!

The funny thing is that I need to have a paid support plan in order to open a support ticket for a bug since it is considered as a technical support.
