`commons-lang`(1and2) is no longer maintained since 2011, and the official recommendation is `commons-lang3`, which can be smoothly upgraded to be compatible with `commons-lang`.
We use both dependencies in `fe`, which can be completely unified.
`PatternGenerator#generateTypePattern` has many meaningless loops, and IntegerRange is introduced for,
which is unnecessary. So I refactored it.
PR(#17960) has introduced vector table which can map java table to c++ block.
In some cases(java udf & jdbc exector), we should map c++ block to java table. This PR implements this function.
The memory structure of java vector table and c++ block is consistent,
so the implementation doesn't copy the block, just passes the memory address.
now maybe jdbc have problem that there are too many connections and they do not release,
so change the property of datasource: init = 1, min = 1, max = 100, and idle time is 10 minutes.
jdbc read array type get result from Doris is string, PG is java.sql.array, CK is java.lang.object
it's difficult to maintain and read the code,
so change all database's array result to string, then add a cast function from string to doris array type
In clickhouse's 4.x version of jdbc, some UInt types use special Java types, so I adapted Doris's ClickHouse JDBC External
```
com.clickhouse.data.value.UnsignedByte;
com.clickhouse.data.value.UnsignedInteger;
com.clickhouse.data.value.UnsignedLong;
com.clickhouse.data.value.UnsignedShort;
```
A framework that read data from jni scanner, which can support the data source from java ecosystem(java API).
## Java Interface
Java scanner should extends `org.apache.doris.jni.JniScanner`, implements the following methods:
```
// Initialize JniScanner
public abstract void open() throws IOException;
// Close JniScanner and release resources
public abstract void close() throws IOException;
// Scan data and save as vector table
public abstract int getNext() throws IOException;
```
See demo usage in `org.apache.doris.jni.MockJniScanner`
## c++ interface
C++ reader should use `doris::JniConnector` to get data from `org.apache.doris.jni.JniScanner`. See demo usage in `doris::MockJniReader`.
## Pushed-down predicates
Java scanner can get pushed-down predicates by `org.apache.doris.jni.vec.ScanPredicate`.
## Remaining works:
1. Implement complex nested types.
2. Read hudi MOR table as the end-to-end demo usage.
When using JDBC Catalog to query the Doris data, because Doris does not provide the cursor reading method (that is, fetchBatchSize is invalid), Doris will send the data to the client at one time, resulting in client OOM.
The MySQL protocol provides a stream reading method. Doris can use this method to avoid OOM. The requirements of using the stream method are setting fetchbatchsize = Integer.MIN_VALUE and setting ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY

This pr do two things:
1. fix:
It use `column[0]` to judge class type in JdbcExecutor, but column[0] may be null !
2. Enhencement
In the original logic, all fields in jdbc catalog table will be set Nullable.
However, it is inefficient for nullable fields. Actually, we can know if the fields in data source table
is nullable through jdbc. So we can set the corresponding fields in Doris jdbc catalog to nullable or not.
when pg table have some unsupported column type like: point, polygon, jsonb......
jdbc catalog will convert it to string type in doris. but get result set in java is org.postgresql.util.PGobject
Some test need this pr: #16442
Issue Number: close #xxx
This pr fix two bugs:
_jdbc_scanner may be nullptr in vjdbc_connector.cpp, so we use another method to count jdbc statistic. close [Enhencement](jdbc scanner) add profile for jdbc scanner #15914
In the batch insertion scenario, oracle database does not support syntax insert into tables values (...),(...); , what it supports is:
insert all
into table(col1,col2) values(c1v1, c2v1)
into table(col1,col2) values(c1v2, c2v2)
SELECT 1 FROM DUAL;
Fix bug that when create jdbc resource with only jdbc driver file name, it will failed to do checksum
This is because we forgot the pass the full driver url to JdbcClient.
Add ResultSet.FETCH_FORWARD and set AutoCommit to false to jdbc connection, so to avoid OOM when fetching large amount of data
set useCursorFetch in jdbc url for both MySQL and PostgreSQL.
Fix some p2 external datasource bug
Issue Number: close #xxx
I add jdbc catalog for doris multi-catalog feature.
Currently, the jdbc catalog only supports MYSQL DBMS.
TODO:
support for postgre DB
Support for other databases.
Problem summary
For jdbc catalog, we can create catalog like:
CREATE CATALOG jdbc4 PROPERTIES (
"type"="jdbc",
"jdbc.user"="root",
"jdbc.password"="123456",
"jdbc.jdbc_url" = "jdbc:mysql://127.0.0.1:13396/demo?yearIsDateType=false",
"jdbc.driver_url" = "file:/mnt/disk2/ftw/tools/jar/mysql-connector-java-5.1.47/mysql-connector-java-5.1.47.jar",
"jdbc.driver_class" = "com.mysql.jdbc.Driver"
);
Note:
yearIsDateType is a param of jdbc:
If yearIsDateType configuration property is set to false, then the returned object type is java.sql.Short. If set to true (the default), then the returned object is of type java.sql.Date with the date set to January 1st, at midnight.
To compat with mysql, we force the use of yearIsDateType=false in FE. if user sets yearIsDateType=true, doris FE will force to change yearIsDateType=false.
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
