What kind of actions belong to Small Datastore Operations?

[zhaiduo]

Hi All,

My little app became over quota on Small Datastore Operations
recently. What the most confused me is what kind of actions belong to
Small Datastore Operations? I can't figure it out. Can anyone give me
the detail for this?

Appreciate your help!

Most of the time, it's COUNT queries that is causing over-quota for small ops. It costs 1 small op per entity counted. You should use a counter entity instead, sharding it if necessary.
The rest of the time it's using OFFSET + LIMIT queries. Each offset value costs 1 small small op. You should use cursors instead

I found that the COUNT query was the killer. Once I removed it, my
small op usage went way down.
