jiangxt2 opened a new pull request, #13419: URL: https://github.com/apache/gravitino/pull/13419
### What changes were proposed in this pull request? This change adds read-only loading of native ClickHouse text data-skipping index metadata. It recognizes the `text`, `gin`, `full_text`, and `inverted` type names, restores supported `tokenizer` and `ngram_size` properties from `type_full`, and preserves fallback to legacy `type` metadata. The new `DATA_SKIPPING_TEXT` enum is covered by JSON/OpenAPI updates and catalog documentation. ### Why are the changes needed? Loading a ClickHouse table through Gravitino should preserve its native text-index type and supported tokenizer metadata through the existing table API. Fix: #11934 ### Does this PR introduce _any_ user-facing change? Yes. Loaded table metadata exposes the `DATA_SKIPPING_TEXT` type and supported tokenizer values (`tokens` or `ngrams`); `ngram_size` is exposed for `ngrams`. Creating or altering text indexes through Gravitino remains unsupported. ### How was this patch tested? - `./gradlew :catalogs-contrib:catalog-jdbc-clickhouse:test --tests org.apache.gravitino.catalog.clickhouse.operations.TestClickHouseTableOperationsUnit` — 67 tests passed. - `./gradlew :common:test --tests org.apache.gravitino.json.TestJsonUtils` — 13 tests passed. - `./gradlew :docs:build` — passed. - `./gradlew :catalogs-contrib:catalog-jdbc-clickhouse:test --tests org.apache.gravitino.catalog.clickhouse.integration.test.CatalogClickHouseIT.testLoadNativeTextDataSkippingIndexes -PskipDockerTests=false` — 1 test passed. - `./gradlew :catalogs-contrib:catalog-jdbc-clickhouse:test --tests org.apache.gravitino.catalog.clickhouse.integration.test.CatalogClickHouseClusterIT -PskipDockerTests=false` — 20 tests passed. -- This is an automated message from the Apache Git Service.
