…mon table (apache#57821) Problem Summary: support varbinary type in hive/iceberg/paimon table, could mapping varbinary type into doris directly, not of use string type, could use catalog properties enable.mapping.varbinary control it, and default is false. and TVF function, eg HDFS also have param could control, and default is false. 1. when parquet file column type is tparquet::Type::BYTE_ARRAY and no logicalType and converted_type，read it to column_varbianry directly. so both physical convert and logical convert are consistent. if tparquet::Type::BYTE_ARRAY and have set logicalType, eg String, so those will be reading as column_string, and if the table column create as binary column, so VarBinaryConverter used convert column_string to column_varbinary. 2. when orc file column is binary type, also mapping to varbinary type directly, and could reuse StringVectorBatch. 3. add cast between string and varbinary type. 4. mapping UUID to binary type instead of string in iceberg . 5. change the bool safe_cast_string(**const char\* startptr, size_t buffer_size**, xxx) signature to safe_cast_string(**const StringRef& str_ref**, xxx). 6. add **const** to read_date_text_impl function. 7. add some test with paimon catalog test varbinary, will add more case for hive/iceberg and update doc. ``` mysql> show create table binary_demo3; +--------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +--------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | binary_demo3 | CREATE TABLE `binary_demo3` ( `id` int NULL, `record_name` char(10) NULL, `vrecord_name` text NULL, `bin` varbinary(10) NULL, `varbin` varbinary(2147483647) NULL ) ENGINE=PAIMON_EXTERNAL_TABLE LOCATION 'file:/mnt/disk2/zhangsida/test_paimon/demo.db/binary_demo3' PROPERTIES ( "path" = "file:/mnt/disk2/zhangsida/test_paimon/demo.db/binary_demo3", "primary-key" = "id" ); | +--------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec) mysql> select *, length(record_name),length(vrecord_name),length(bin),length(varbin) from binary_demo3; +------+-------------+--------------+------------------------+----------------+---------------------+----------------------+-------------+----------------+ | id | record_name | vrecord_name | bin | varbin | length(record_name) | length(vrecord_name) | length(bin) | length(varbin) | +------+-------------+--------------+------------------------+----------------+---------------------+----------------------+-------------+----------------+ | 1 | AAAA | AAAA | 0xAAAA0000000000000000 | 0xAAAA | 10 | 4 | 10 | 2 | | 2 | 6161 | 6161 | 0x61610000000000000000 | 0x6161 | 10 | 4 | 10 | 2 | | 3 | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | +------+-------------+--------------+------------------------+----------------+---------------------+----------------------+-------------+----------------+ ``` support varbinary type mapping in hive/iceberg/paimon table
