delete the Chaos Cosmos folder from your documents 3. The change feed could be used to upsert the latest event, such that the latest event is created/overwritten in the "LatestEvent" container as its source item is created in the main. uninstall Chaos Cosmos browser from programs 2.
#LAST STOP COSMOS NO THANKS. SERIAL#
We denormalizeįollowing this approach, you could create a "Feed" or "LatestEvent" container dedicated to the "latest" query which uses the device serial as id and having a single partition key in order to guarantee that there is only one (the most recent) event item per device, and that it can be fetched by the device serial or listed with least possible cost using a simple query: SELECT * Our design, entirely dedicated to serving this request. So to optimize this last request, we introduce a third container to We just need to get the 100 most recent posts, without the need to This guide on partitioning and modeling has a relevant section on getting the latest items in a feed. If the question is really about an efficient approach to this particular query scenario, we can consider denormalization in cases where the query language itself doesn't offer an efficient solution. cant do select *) SELECT c.serial, MAX(c.EventProcessedUtcTime) So doing the following returns the correct data but sadly you can only return data thats inside your group by or an aggregate function (i.e. "_self": "dbs/i2UhAA=/colls/i2UhAI7ofAo=/docs/i2UhAI7ofAo3AQAAAAAAAA=/", Send it to and include a link to this forum post as well. "id": "6dac491e-1f28-450d-bf97-3a15a0efaad8", Hi jakub007, Please, send is the cb.log file which is stored by default under C:\Program Files\Common Files\ChaosGroup\ChaosCosmos. Im assuming I would need to use Group By - Īny assistance would be greatly appreciated WHERE c.serial IN ('V55555555','synap-aim-g1') ORDER BY c.EventEnqueuedUtcTime DESC We have device data stored within a collection and would love to retrieve the latest event data per device serial effectively without having to do N queries for each device separately. I am using Azure Cosmos DB SQL API to try to achieve the following
