We have two es clusters, one running on premise and another one on the cloud.
The one premise one can't store data for more than a week.
The cloud cluster retains the data for a longer duration (a few months).
So the indexed documents need to be moved to the cloud with in an hour.
The size of the data for an hour is a few Mbs.
What would the best approach to move the data to the cloud ?
I went through CCR - but doesn't look like a good candidate for this use case.
