Design Documentation Linked to #25514 Regression test add a new group: arrow_flight_sql, ./run-regression-test.sh -g arrow_flight_sql to run regression-test, can use jdbc:arrow-flight-sql to run all Suites whose group contains arrow_flight_sql. ./run-regression-test.sh -g p0,arrow_flight_sql to run regression-test, can use jdbc:arrow-flight-sql to run all Suites whose group contains arrow_flight_sql, and use jdbc:mysql to run other Suites whose group contains p0 but does not contain arrow_flight_sql. Requires attention, the formats of jdbc:arrow-flight-sql and jdbc:mysql and mysql client query results are different, for example: Datatime field type: jdbc:mysql returns 2010-01-02T05:09:06, mysql client returns 2010-01-02 05:09:06, jdbc:arrow-flight-sql also returns 2010-01-02 05:09 :06. Array and Map field types: jdbc:mysql returns ["ab", "efg", null], {"f1": 1, "f2": "a"}, jdbc:arrow-flight-sql returns ["ab ","efg",null], {"f1":1,"f2":"a"}, which is missing spaces. Float field type: jdbc:mysql and mysql client returns 6.333, jdbc:arrow-flight-sql returns 6.333000183105469, in query_p0/subquery/test_subquery.groovy. If the query result is empty, jdbc:arrow-flight-sql returns empty and jdbc:mysql returns \N. use database; and query should be divided into two SQL executions as much as possible. otherwise the results may not be as expected. For example: USE information_schema; select cast ("0.0101031417" as datetime) The result is 2000-01-01 03:14:1 (constant fold), select cast ("0.0101031417" as datetime) The result is null (no constant fold), In addition, doris jdbc:arrow-flight-sql still has unfinished parts, such as: Unsupported data type: Decimal256. INVALID_ARGUMENT: [INTERNAL_ERROR]Fail to convert block data to arrow data, error: [E3] write_column_to_arrow with type Decimal256 Unsupported null value of map key. INVALID_ARGUMENT: [INTERNAL_ERROR]Fail to convert block data to arrow data, error: [E33] Can not write null value of map key to arrow. Unsupported data type: ARRAY<MAP<TEXT,TEXT>> jdbc:arrow-flight-sql not support connecting to specify DB name, such asjdbc:arrow-flight-sql://127.0.0.1:9090/{db_name}", In order to be compatible with regression-test, use db_nameis added before all SQLs whenjdbc:arrow-flight-sql` runs regression test. select timediff("2010-01-01 01:00:00", "2010-01-02 01:00:00");, error java.lang.NumberFormatException: For input string: "-24:00:00"
