Description
As per the documentation[0],
To modify the below parameters, we have to edit the file `loki.yaml` but there is no such file as `loki.yaml` since the lokistack is operator managed, we need to edit the file using `oc edit lokistack`, there are no clear examples on where and how to add these parameters in lokistack
grpc_server_max_recv_msg_size: 8388608 chunk_target_size: 8388608 ingestion_rate_mb: 8 ingestion_burst_size_mb: 16
For the Demo, I have updated the lokistack as below
Example
oc edit lokistack

what are the other parameters that can be configured using the `Lokistack` do we have a list of that parameters
For the below parameter, We cannot configure them as they are not available in the https://loki-operator.dev/docs/api.md/ , having these parameters in the doc in confusing the customer
- grpc_server_max_recv_msg_size: 8388608
- chunk_target_size: 8388608
