Opt zstd block decompression by `ZSTD_decompressDCtx()` to replace streaming decompression.
It will improve performance but consume more memory.
Test result:
- env: 1 node(16 cores, 64G).
- parquet column: 100 million rows of char(255) column.
- result: 5.2 -> 4.6.
Fix null map issue in parquet reader which cause result incorrect such as `min()`, `max()`.
In order to share null map between parquet converted src column and dst column to avoid copying. It is very tricky that will call mutable function `doris_nullable_column->get_null_map_column_ptr()` which will set `_need_update_has_null = true`. Because some operations such as agg will call `has_null()` to set `_need_update_has_null = false`.
Add tpcds sf100 hive shapes.
Disable query64 temporarily because it is not same with emr cluster after collecting metadata by analyze table xxx.
And the root cause need to analyze, will enable in future PR.
1. Change the external hive docker network mode from the bridge mode to the host mode to support the external test of the multi-node doris cluster
2. Added more hive test data in various formats
3. Added a test case with hive
Load data from hdfs in hive will move the source directory into table's location directory, leading the error like Can not get first file, please check uri in tvf test.
`Wrong data type for column` error when column order in hive table is not same in orc file schema.
The root cause is in order to handle the following case:
The table in orc format of Hive 1.x may encounter system column names such as `_col0`, `_col1`, `_col2`... in the underlying orc file schema, which need to use the column names in the hive table for mapping.
### Solution
Currently fix this issue by handling the following case by specifying hive version to 1.x.x in the hive catalog configuration.
```sql
CREATE CATALOG hive PROPERTIES (
'hive.version' = '1.x.x'
);
```
After supporting insert-only transactional hive full acid tables #19518, #19419, this PR support transactional hive full acid tables.
Support hive3 transactional hive full acid tables.
Hive2 transactional hive full acid tables need to run major compactions.
We can support this by add a new properties for tvf, like :
`select * from hdfs("uri" = "xxx", ..., "compress_type" = "lz4", ...)`
User can:
Specify compression explicitly by setting `"compression" = "xxx"`.
Doris can infer the compression type by the suffix of file name(e.g. `file1.gz`)
Currently, we only support reading compress file in `csv` format, and on BE side, we already support.
All need to do is to analyze the `"compress_type"` on FE side and pass it to BE.
Fix some hive partition issues.
1. Fix be will crash when using hive partitions field of `date`, `timestamp`, `decimal` type.
2. Fix hdfs uri decode error when using `timestamp` partition filed which will cause some url-encoding for special chars, such as `%3A` will encode `:`.
When creating an external catalog, Doris will automatically sync the schema of table from external catalog.
But some of column type are not supported by Doris now, such as struct, map, etc.
In previous, when meeting these unsupported column, Doris will throw an exception, and the corresponding
table can not be synced. But user may just want to query other supported columns.
In this PR, I add a new column type: UNSUPPORTED. And now it is just used for external table schema sync.
When meeting unsupported column, it will be synced as column with UNSUPPORTED type.
When query this table, there are serval situation:
select * from table: throw error Unsupported type 'UNSUPPORTED_TYPE' xxx
select k1 from table: k1 is with supported type. query OK.
select * except(k2): k2 is with unsupported type. query OK
Add tpch 1g orc test case in hive docker
Refactor some suites dir of catalog test cases.
And "-internal" for dlf endpoint, to support access oss with aliyun vpc.
BE will crash when querying partitioned hive table with text format
and put partition column at first of select items.
1. FE should use file slots to set the column mapping index of csv file.
2. BE should use `get_by_name` of block to get right column in a block in csv reader.
Add regression test for external hive orc table. This PR has generated all basic types support by hive orc, and create a hive external table to touch them in docker environment.
Functions to be tested:
1. Ensure that all types are parsed correctly
2. Ensure that the null map of all types are parsed correctly
3. Ensure that the `SearchArgument` of `OrcReader` works well
4. Only select partition columns
Issue Number: close#12574
This pr adds `NewJsonReader` which implements GenericReader interface to support read json format file.
TODO:
1. modify `_scann_eof` later.
2. Rename `NewJsonReader` to `JsonReader` when `JsonReader` is deleted.
1. Modify default behavior of `build.sh`
The `BUILD_JAVA_UDF` is default ON, so that jvm is needed for compilation and runtime.
2. Add docker-compose for MySQL 5.7, PostgreSQL 14 and Hive 2
See `docker/thirdparties/docker-compose`.
3. Add some regression test cases for jdbc query on MySQL, PG and Hive Catalog
The default is `false`, if set to true, you need first start docker for MySQL/PG/Hive.
4. Support `if not exists` and `if exists` for create/drop resource and create/drop encryptkey
