当集合已经存在时，如何在集合级别为documentdb启用DefaultTimeToLive（TTL）？

Question

I have tried using :- collection.DefaultTimeToLive = CloudSettings.GetDataRetentionPeriod() * 86400; collection.SetPropertyValue("DefaultTTL", CloudSettings.GetDataRetentionPeriod() * 86400);

But its not enabling the TTL property as we can see from the azure portal

Answer 1

For me, DefaultTimeToLive works:

collection.DefaultTimeToLive = <your-value-here>;
var response = await _client.ReplaceDocumentCollectionAsync(collection, request.RequestOptions);
