v0.4.0

Sync of the upstream enum-validation + narrow-bind batch (vgi 28539a4..129aff1, vgi-python 59e332b/595481d). Full launcher suite green (178 pass / 13 skip / 0 fail); CI green on all three lanes (launch / http / shm).

Changes

• fix(serializer): emit canonical order_preservation wire names (PRESERVES_ORDER / NO_ORDER_GUARANTEE / FIXED_ORDER). vgi now throws on any unrecognized wire enum (was: silent default for all but function_type), which surfaced this latent bug. Added OrderPreservation.wireName() (enum constants stay DuckDB-aligned).
• feat(catalog): extra-catalog tables — Worker.registerExtraCatalogTable + routing in the four catalog-table RPCs, backing the narrow_bind reproducer catalog (a worker whose bind output_schema is narrower than the table it advertises must fail closed at bind, not segfault the client).
• feat(fixtures): query_seed scalar (the only CONSISTENT_WITHIN_QUERY fixture), overlapping_range_partitioned table fn (the only OVERLAPPING_PARTITIONS fixture), and the bad_enum fixture worker (advertises an unrecognized null_handling to exercise the C++ strict-enum rejection).

Depends on farm.query:vgirpc:0.10.2 (unchanged).

v0.3.0

farm.query:vgi 0.3.0

Tracks upstream VGI main / Haybarn v1.5.4-rc1. Ports the new test-suite
features and fixes numeric type promotion. Suite: 185/185.

Core (farm.query:vgi)

• Numeric promotion — add_values/double now promote like the canonical
  Python worker: decimals gain a digit of precision, unsigned integers widen
  one tier, decimal addition merges precision/scale (TypeRules,
  ScalarHelpers unsigned + new toBigDecimal).
• Pushdown introspection — new PushdownFilters.filteredColumns() and
  hasFilterForColumn().
• Typed const decoding — VectorScalarCodec.read now decodes timestamp and
  unsigned-integer scalars predictably.

Example worker fixtures

• typed_probe table function (typed const args: TIMESTAMPTZ / INTERVAL / BLOB
  / UBIGINT with worker-side defaults).
• filtered_columns_echo table function (filter-column introspection).
• secret_field and scale_by_setting scalar functions.

Depends on farm.query:vgirpc:0.10.2.

v0.2.0

Second release of farm.query:vgi to Maven Central.

Highlights since 0.1.0

• Expression-filter pushdown — new PushdownFilter.Expression wire decode + PushdownFiltersDecoder rendering pushed expression trees (column refs, constants, functions, comparisons, conjunctions, geoarrow.wkb) to SQL predicates, with FunctionMetadata.withSupportedExpressionFilters(...) capability wiring.
• HTTP transport hardening — the framework's filter / buffering producers are now serializable across the stateless HTTP transport's continuation tokens (no-arg ctors, plain-POJO state, a static storage holder that re-binds on resume). Pairs with vgirpc 0.10.2's state-serialization fixes.
• Integration CI — the upstream vgi sqllogictest suite now runs on every push across three transport lanes (launch, shm, http) against the prebuilt haybarn-unittest + signed community vgi extension.

Depends on farm.query:vgirpc:0.10.2.

v0.1.0

First release of farm.query:vgi to Maven Central.

Java implementation of the VGI (Vector Gateway Interface) protocol for serving
catalog data to Haybarn, Query Farm's DuckDB-derived engine, from external
workers over Apache Arrow IPC.
