Fields

dsn_env: String

database_name: String

table: String

overwrite: bool

Legacy bool field from 0.3.x — accepted but never preferred. New configs should use mode. Top-level target.overwrite: true is still rejected at config-load by the legacy-form check (Task 13).

hnsw: bool

vector_metric: String

Postgres/pgvector semantic-search metric: cosine, inner_product, or l2.

mode: String

overwrite (default), append, or create_if_missing. All three are implemented in Rust as of MB-3 (sink full-mode parity).

source_tag: Option<String>

promote_metadata: Vec<PromoteColumn>

force_overwrite: bool

delete_orphans: bool

When true, after upserting chunks for a document, delete any rows for that document with seq_num >= len(new_chunks). Closes the per-doc shrink gap (last run wrote 12 chunks; this run writes 8 → drop the 4 orphans inside the same write transaction). Default false to preserve the historical behavior. See docs/incremental.md.

memory: Option<MemoryConfig>

RM-A: when present, load_sink returns a MemorySink (extends PgSink with tier/kind stamping + supersede + soft-invalidate). Mirror of Python chunkshop.config.TargetConfig.memory.

documents: Option<DocumentStoreConfig>

Python/Postgres-only document table config. Rust rejects enabled document stores explicitly so cross-language YAMLs cannot silently ingest chunks without the companion document rows.
