load_method: upsert-on-conflictthat upserts via a singleINSERT ... ON CONFLICT (key_properties) DO UPDATE SET .... Significantly faster on large TimescaleDB hypertables, where the existing MERGE-style UPDATE forces decompression of every chunk the staging key-set touches.Benchmark: ~29 min/batch vs ~0.8s/batch on a ~19k-chunk compressed hypertable with ~100M records.
