Yes, exactly. You'll push events from Alooma's Android SDK and they'll land in your Redshift in seconds.
You can have a look at the documentation here:

Alooma not loading into a JSON column, but provides mapping UI and transformation layer to in order structure and normalize the data into different appropriate columns, thus leverages the columnar storage properties.

no api key ?
this looks interesting - but it would be nice to be able to get started immediately without "request a demo".
