Hi, I am from Cosmos DB engineering team.

For SQL API, the collection names have a limit of 255 bytes (we will update the documentation). For Mongo API, we honor the limit prescribed by the API for the combination of <database>.<collection> to be 120 bytes as explained here - https://docs.mongodb.com/manual/reference/limits/#Restrictio...

We continue to optimize our indexing layout – there are several key improvements being rolled out. Please share the details of your expensive query ([e-mail]) to help us investigate.

OFFSET/LIMIT (Skip/Take) is currently in private preview. It will be broadly available by 5/15/2019.

We are working on customer controlled PITR, which will be available later this year.

Thank you for the feedback!
