Prompt 1

Implement the following plan:

Fix: Memory Escalation in flattenCheckpointFile (68GB+)

Context

Production gops shows flattenCheckpointFile allocating 68GB+ (74.89% of memory). The archiving pipeline accumulates ALL metric data from ALL hosts into a single []ParquetMetricRow slice before writing to Parquet. For large HPC clusters this is catastrophic. Additionally, the SortingWriterConfig in the parquet writer buffers everything again internally.

Root Cause

Two-layer unbounde...

Prompt 2

Are the any other cases with memory spikes using the Parquet Writer, e.g. in the nodestate retention?
