Hi,  
I am trying to figure out the how to create a monthly rolling index with custom routing (multi-tenancy scenario) , with these requirements :

- WRITE flow : Each document will have a timestamp and the document should be indexed to the appropriate backing index based on that timestamp and not to the latest index. Also, write requests will have a custom routing key (eg: customerId) so they hit a specific shard.
- READ flow : Requests must be routed to all backing indexes. Requests will have a custom routing key specified (eg: customerId) and results must be aggregated and returned.
- Index creation : Rolling the index should be automated. Each index should have a custom routing key (eg: customerId )

Wondering, what are the options available ?

Welcome to our community! 😃

Given your first condition, you will need to handle this all yourself using time based indices and curator (or similar).
