Bring CalcitePPLBasicIT to parity on the analytics-engine route (opensearch-project#5542)

ahkcs · web-flow · commit 87c0a13ca17f · 2026-06-12T13:47:15.000-07:00
Guard raw-document seeding in init() with isIndexExist: the parquet/composite store is append-only on a same-_id PUT, so re-seeding test/test1 on every @before inflated their row counts across the class. Pin SELECT-* and fields- column order with an explicit | fields, since the analytics-engine route returns columns in storage (alphabetical) order rather than mapping order. Branch the tests that exercise analytics-route-incompatible behavior behind isAnalyticsParquetIndicesEnabled(): alias/nested field storage, decimal-vs-double literal arithmetic, multi-index integer/long schema merge, and the implicit search-filter syntax. Depends on opensearch-project#5541, which strips analytics-engine-unsupported field types at load and unblocks index creation for this class. Analytics-engine route: 46 failing -> 0 failing (39 pass, 7 documented skips). v2 route: 46/46 pass. Signed-off-by: Kai Huang <ahkcs@amazon.com>
