Lightstep has recently changed their pricing, it's now the most cost effective option out there. You pay $100 per service with basically unlimited data ingestion, it's a fabulous deal. https://lightstep.com/pricing/

As for scrubbing PII, they are now supporting the OpenTelemetry tracing API which does this as standard. For query endpoints you will see something like "QUERY Users where name=? email=?", i.e. masking with "?" chars as you only care about the keys since those what determine your indexing or lack thereof. (This is handled in the OpenTelemetry application library/plugin level.)

As an aside, PII scrubbing should be done that whether or not you own the cluster, because even if you own the cluster you generally don't want your support staff seeing PII esp. as organization grows larger.
