Last9 offers [streaming aggregations](https://last9.io/docs/streaming-aggregations/) as one way to manage [high cardinality](https://last9.io/guides/high-cardinality/) metrics. With this release, we are adding sharding support to the streaming aggregation pipeline to improve performance and reliability.

The release includes -

- Ability to shard across a set of upstream remote writers. This allows better reliability for the streaming aggregation pipeline.
- Client-side load balancing across a set of upstream remote writers. This lowers the overall TCO and simplifies deployment topology.
