I'll ask about opensourcing the tool. But just in case, the recipe is to use pipe mode and pre-parse all frames, stream them as messages, sometimes to several targets (pub/sub) with some streaming-zstd, and also splitting the pmu/probes/Intel-PT streams and treating them separately. Stack-traces are analysed (precomputed cfg optimised structure so unwinding is faster) before storing in adhoc in-house format with all other system traces. Only annoying thing is changing perf-record settings (pid changes, need event X, new probe) means restart and I ran out of interns before we had no-loss switchover...
