TSS records details about each tx and block into RocksDB and is single threaded. This can be a giant bottleneck at high TPS. This service is not required for standard validator operation but is used to supply the data necessary for responding to certain RPC queries.

On invalidator runs, we observe this service lagging behind and causing OOM issues (due to tx updates growing an unbounded crossbeam channel) at ~40k TPS.
