# Grafana Tempo — single-binary, all-in-one, local storage (S-16a, ADR-0023).
# Ingests OTLP directly (services export straight to Tempo; no collector hop).
# Storage is ephemeral container fs — this is a local/CI demo backplane, not a
# retention target. ponytail: local backend, swap for object storage if traces
# must outlive the stack.

# #156: don't let the distributor evict its own ingester. Tempo runs single-binary here, so the
# distributor and the ingester are the same process and the "pool" holds exactly one, in-process,
# member. dskit still health-checks it over loopback gRPC with a 1s deadline (checkinterval 15s);
# on the shared CI runner a transient stall blows that deadline, the only ingester is dropped from
# the pool ("removing distributor_pool failing healthcheck"), and every push then fails ("pusher
# failed to consume trace data", err="context canceled") until the next check — silently losing
# spans, which is how verify-tracing flaked. With one in-process ingester the check can never route
# around a failure, so it can only ever discard data. Turn it off.
