Gahow Wang 8a876e90d1 traces/README: clarify w600 is the session-start window, not span
The trace actually spans ~2912 s (~48.5 min): all 274 sessions START within
the 600 s --window-seconds window, but their later multi-turn requests (34%
of rows, inter-turn gaps up to ~700 s) extend well past t=600 s. Remove the
misleading "~600 s span".

Benchmark trace

w600_r0.0015_st30.jsonl

The primary replay trace for the routing / connector experiments (1214 requests, 274 sessions). One JSON object per request:

{"chat_id": 1237198, "parent_chat_id": -1, "timestamp": 0.0,
 "input_length": 8228, "output_length": 21, "type": "coder", "turn": 1,
 "hash_ids": [12292995, ...], "session_id": "1237198"}
field meaning
input_length / output_length token counts only
hash_ids opaque integer KV-block hashes — shared ids ⇒ shared prefix (drives prefix-cache reuse in replay)
timestamp arrival offset (s) from trace start
turn / parent_chat_id / session_id multi-turn session structure

No cleartext. There are no prompts, no model outputs, and no PII — only token counts, opaque block hashes, timing, and session structure. The replayer synthesizes dummy token sequences consistent with hash_ids so prefix-cache hit rates match the original workload.

Provenance

Sampled from the internal Alibaba GLM-5.1-formatted production trace (~/ali-trace/trace-glm5.1-formatted/051315-051317.jsonl on dash0, ~2.1 M requests, 2 h) — not redistributable; only this anonymized sample is shipped. The filename encodes the sampling params: w=window-seconds, r=sample-ratio, st=max-single-turn-ratio.

w600 is the 600 s window of session start times, not the trace duration. The sampler keeps every session whose first request falls in a 600 s window, then includes all of that session's turns. Because agentic sessions are long-lived multi-turn (inter-turn gaps up to ~700 s), the actual trace spans ~2912 s (~48.5 min) even though all 274 sessions start within the first 598 s; 34 % of requests are later turns occurring after t=600 s.

Regenerate (requires the dash0 source):

    --input ~/ali-trace/trace-glm5.1-formatted/051315-051317.jsonl \
    --output traces/w600_r0.0015_st30.jsonl \
