Fastest way of querying for latest items in a Azure table?

Question

I have a Azure table where customers post messages, there may be millions of messages in a single table. I want to find the fastest way of getting the messages posted within

Answer 1

The Primary key for Table is the combination of PartitionKey and RowKey(which forms a clustered index).

In your case, just go for RowKey instead of ParitionKey(provide a constant value for this).

You can also follow the Diagnostics approach, like for every ten minutes create a new Partition Key. But this approach is mainly for requirements like Archieving/Purging etc.,
