 The distributor can also rate limit incoming logs based on the maximum data ingest rate per tenant. It does this by checking a per-tenant limit and dividing it by the current number of distributors. This allows the rate limit to be specified per tenant at the cluster level and enables us to scale the distributors up or down and have the per-distributor limit adjust accordingly. For instance, say we have 10 distributors and tenant A has a 10MB rate limit. Each distributor will allow up to 1MB/s before limiting. Now, say another large tenant joins the cluster and we need to spin up 10 more distributors. The now 20 distributors will adjust their rate limits for tenant A to `(10MB / 20 distributors) = 500KB/s`. This is how global limits allow much simpler and safer operation of the Loki cluster.

+Loki does write deduplication of chunks and index using Chunks and WriteDedupe cache respectively, configured with [ChunkStoreConfig](https://grafana.com/docs/loki/<LOKI_VERSION>/configure/#chunk_store_config).
 The problem with write deduplication when using `boltdb-shipper` though is ingesters only keep uploading boltdb files periodically to make them available to all the other services which means there would be a brief period where some of the services would not have received updated index yet.
 The problem due to that is if an ingester which first wrote the chunks and index goes down and all the other ingesters which were part of replication scheme skipped writing those chunks and index due to deduplication, we would end up missing those logs from query responses since only the ingester which had the index went down.
 This problem would be faced even during rollouts which is quite common.

+Previously we would statically shard queries based on the index row shards configured [here](https://grafana.com/docs/loki/<LOKI_VERSION>/configure/#period_config).
 TSDB does Dynamic Query Sharding based on how much data a query is going to be processing.
 We additionally store size(KB) and number of lines for each chunk in the TSDB index which is then used by the [Query Frontend]({{< relref "../../get-started/components#query-frontend" >}}) for planning the query.
 Based on our experience from operating many Loki clusters, we have configured TSDB to aim for processing 300-600 MBs of data per query shard.
