Hi everyone, We have an Azure Cosmos DB container that gets populated with batched entries and currently they get sorted by the "c_ts" JSON value. I would like them to be sorted by "creationDate" value in Oldest to Newest order. Is there a way I can do that, maybe with the Indexing Policy for that container? Kind regards Chris.

Chris Buley Thank you for clarifying this. Yes, the indexing policy you’ve provided aims to sort the entries in your Azure Cosmos DB container by the “creationDate” value in Oldest to Newest order. { "automatic":true, "indexingMode":"Consistent", "includedPaths":[ { "path":"/*" } ], "excludedPaths":[], "compositeIndexes":[ [ { "path":"/creationDate", "order":"ascending" } ] } Manage indexing policies in Azure Cosmos DB Regards, Oury

{ "automatic":true, "indexingMode":"Consistent", "includedPaths":[ { "path":"/*" } ], "excludedPaths":[], "compositeIndexes":[ [ { "path":"/creationDate", "order":"ascending" } ] }

The above won't work as composite indexes require 2 paths!

The provided indexing policy indeed has a single composite index on the “creationDate” field in ascending order. However, you are correct that composite indexes typically require at least two paths.

Here’s an updated indexing policy that includes both the “creationDate” field and another field (e.g., “id” or “partitionKey”):

JSON

{ "automatic": true, "indexingMode": "Consistent", "includedPaths": [ { "path": "/creationDate/?", "indexes": [ { "kind": "Range", "dataType": "Number", "precision": -1, "min": "-9223372036854775808", "max": "9223372036854775807" }, { "kind": "Hash", "dataType": "String", "precision": 3 } ] }, { "path": "/id/?" } ], "excludedPaths": [] }

You can adjust the second path according to your specific requirements.Regards,

Oury
