| ### Solution 2 - A generic "sharding" configuration for the Agent remote write | ||
|
|
||
| The [```prometheus.remote_write```](https://grafana.com/docs/agent/latest/flow/reference/components/prometheus.remote_write/) Flow component could be expanded to be able to shard the writes into different remote writes under the hood. Each of these shards would have its own write-ahead log (WAL). Also, each shard would be able to remote write to a different endpoint address and with different HTTP header information. |

Note: Caching of series refs is per WAL, so if tenants have a lot of overlap with series, this can lead to ballooning memory usage.

Good point, thank you, I added this to the "cons" list. Although not sure if it's a "con" it's more like just something to keep in mind.

There is also https://github.com/blind-oracle/cortex-tenant which seems to fit the needs? |
