# Planner profiling data ConfigMap
#
# The planner requires pre-deployment profiling data (prefill & decode
# interpolation curves) for throughput-based scaling.  The values below are
# PLACEHOLDERS for Qwen/Qwen3-0.6B — replace them with real measurements
# before deploying to production.
#
# How to obtain real data:
#   • Run the Dynamo Profiler against your target GPU/model combination.
#     See docs/components/profiler/profiler-guide.md for instructions.
#   • Or run manual benchmarks and fill in the arrays below.
#
# Key format (JSON files mounted into the planner container):
#   prefill_raw_data.json — prefill_isl (input sequence lengths),
#       prefill_ttft (time-to-first-token in ms), prefill_thpt_per_gpu
#       (tokens/s per GPU) — all 1-D arrays of equal length.
#   decode_raw_data.json  — x_kv_usage (KV-cache utilisation fractions),
#       y_context_length (context lengths), z_itl (inter-token latency in ms),
#       z_thpt_per_gpu (tokens/s per GPU), max_kv_tokens (scalar).
#       x_kv_usage, y_context_length, z_itl, and z_thpt_per_gpu must all be
#       flat 1-D arrays of the same length (one entry per measurement point).
