We introduce a caching mechanism in the API gateway layer, allowing us to offload processing from singleton leader elected controllers without giving up strict data consistency and guarantees clients observe. For example, it is OK to send writes through one instance, and do reads from another one with full data read consistency guarantees.

Elasticsearch recommends each shard to be under 65GB (AWS recommends them to be under 50GB), so we could create time based indices where each index holds somewhere between 16–20GB of data, giving some buffer for data growth. For every asset indexing request, we look at the cache to determine the corresponding time bucket index for the asset.
