Jaeger Collector cli flag cassandra.index.logs: false isnt working

[jay-annapureddy]

Hi,
I am using Jaeger collector 1.50 version with azure cosmosdb cassandra api and using couple of cli flags not to persist the span tags but it isnt working as i see those tags on the Jaeger UI, could you please help what is wrong here ?

I followed this guide https://grafana.com/blog/2020/07/30/how-to-maximize-span-ingestion-while-limiting-writes-per-second-to-a-scylla-backend-with-jaeger-tracing/ but it isnt working, see my deployment file below and suggest

--cassandra.index.logs
Controls log field indexing. Set to false to disable.
--cassandra.index.process-tags
Controls process tag indexing. Set to false to disable.
--cassandra.index.tag-blacklist
The comma-separated list of span tags to blacklist from being indexed. All other tags will be indexed. Mutually exclusive with the whitelist option.
--cassandra.index.tag-whitelist
The comma-separated list of span tags to whitelist for being indexed. All other tags will not be indexed. Mutually exclusive with the blacklist
option.

Hi @joe-elliott @jpkrohling,
could you please assist on this ?

Indexing tags is not the same as storing them - Jaeger does not drop data, all tags are still going to be stored and visible in the UI, but if you exclude them from indexing then you cannot search traces via these tags.
