Only do implementation in cascades.
In order to achieve the ssb test, at this stage, temporarily comment out the explore rule process in cascades.
It needs to be added in the future.
PropertyAnalyzer.analyzeDataProperty(Map<String, String> properties, final DataProperty oldDataProperty) has something not suitable.
Parameter oldDataProperty is the old DataProperty, properties should be used to replace some of its members.
If properties has no some members, old ones need to be left, but not be set to default value.
Function modifyPartitionsProperty() uses analyzeDataProperty(), but create a new DataProperty again, it is duplicate.
Add related expressions and AggPlan and SortPlan.
This PR includes the addition of the following expression types:
Arithmetic/BetweenPredicate/CompoundPredicate/FunctionCall.
PlanNode:
LogicalAggregation/LogicalSort
Add a ut to verify related expressions and node parsing
Supported:
1. Change FeMetaVersion to 111, compatible with upgrade from 110.
2. Add catalog level privileges, and degrade global level privileges to catalog level if FeMetaVersion < 111.
3. Support 'show all grants', 'show roles' statement.
4. Previous version of SQL syntax.
Todo:
1. three-segment format catalog.database.table in SQL syntax.
2. User document for the unified authority management of datalake.
3. LDAP services to provide authentication.
As the statistics framework could not be reused by new optmizer before, so I abstract some interface to make it reusable.
1. Make Slot extends the Id
2. Add new interface:ExprStats,PlanStats
3. Move definition of PlanNode.NodeType to statistics sub-directory
Add remote storage policy config for create table properties. It will set storage policy for table and partitions in `CREATE TABLE` and `ALTER TABLE`.
This policy will be used when partition is being migrated from local to remote.
grammy:
1.
`CREATE TABLE TblPxy1
(...)
ENGINE=olap
DISTRIBUTED BY HASH (aa) BUCKETS 1
PROPERTIES(
"remote_storage_policy" = "testPolicy3"
);`
2.
`ALTER TABLE TblPxy01 SET ("remote_storage_policy" = "testPolicy3");`
3.
`ALTER TABLE TblPxy01 MODIFY PARTITION p2 SET ("remote_storage_policy" = "testPolicy3");`
FEFunctionSignature do not support ArrayType as args, then following SQL failed:
`> select array_contains([1,2,3], 1);`
ERROR 1105 (HY000): errCode = 2, detailMessage = Unexpected exception: org.apache.doris.catalog.ArrayType cannot be cast to org.apache.doris.catalog.ScalarType
Currently, when setting variables with `global` keywords, it will not affect the
current session variable's value. That is always make user confused.
This CL mainly changes:
1. Change session variable when set global variable
Now column `Array<T>` contains column `offsets` and `data`, and type of column `offsets` is UInt32 now.
If we call array_union to merge arrays repeatedly, the size of array may overflow.
So we need to extend it before `Array Data Type` release.
1. fix all checkstyle warning
2. change all checkstyle rules to error
3. remove some java doc rules
a. RequireEmptyLineBeforeBlockTagGroup
b. JavadocStyle
c. JavadocParagraph
4. suppress some rules for old codes
a. all java doc rules only affect on Nereids
b. DeclarationOrder only affect on Nereids
c. OverloadMethodsDeclarationOrder only affect on Nereids
d. VariableDeclarationUsageDistance only affect on Nereids
e. suppress OneTopLevelClass on org/apache/doris/load/loadv2/dpp/ColumnParser.java

Support query hive table on S3. Pass AK/SK, Region and s3 endpoint to hive table while creating the external table.
example create table sql:
```
CREATE TABLE `region_s3` (
`r_regionkey` integer NOT NULL,
`r_name` char(25) NOT NULL,
`r_comment` varchar(152) )
engine=hive
properties
("database"="default",
"table"="region_s3",
“hive.metastore.uris"="thrift://127.0.0.1:9083",
“AWS_ACCESS_KEY”=“YOUR_ACCESS_KEY",
“AWS_SECRET_KEY”=“YOUR_SECRET_KEY",
"AWS_ENDPOINT"="s3.us-east-1.amazonaws.com",
“AWS_REGION”=“us-east-1”);
```
This pr support
1. remove the generic type from operator, remove some NODE_TYPE from plan and expression
2. refactor Plan and NODE_TYPE generic type
3. support child class matching by TypePattern
4. analyze the code of operator and generate pattern makes it easy to create rules.
e.g.
```java
class LogicalJoin extends LogicalBinaryOperator;
class PhysicalFilter extends PhysicalUnaryOperator;
```
will generate the code
```java
interface GeneratedPatterns extends Patterns {
default PatternDescriptor<LogicalBinaryPlan<LogicalJoin, Plan, Plan>, Plan> logicalJoin() {
return new PatternDescriptor<LogicalBinaryPlan<LogicalJoin, Plan, Plan>, Plan>(
new TypePattern(LogicalJoin.class, Pattern.FIXED, Pattern.FIXED),
defaultPromise()
);
}
default <C1 extends Plan, C2 extends Plan>
PatternDescriptor<LogicalBinaryPlan<LogicalJoin, C1, C2>, Plan>
logicalJoin(PatternDescriptor<C1, Plan> child1, PatternDescriptor<C2, Plan> child2) {
return new PatternDescriptor<LogicalBinaryPlan<LogicalJoin, C1, C2>, Plan>(
new TypePattern(LogicalJoin.class, child1.pattern, child2.pattern),
defaultPromise()
);
}
default PatternDescriptor<PhysicalUnaryPlan<PhysicalFilter, Plan>, Plan> physicalFilter() {
return new PatternDescriptor<PhysicalUnaryPlan<PhysicalFilter, Plan>, Plan>(
new TypePattern(PhysicalFilter.class, Pattern.FIXED),
defaultPromise()
);
}
default <C1 extends Plan>
PatternDescriptor<PhysicalUnaryPlan<PhysicalFilter, C1>, Plan>
physicalFilter(PatternDescriptor<C1, Plan> child1) {
return new PatternDescriptor<PhysicalUnaryPlan<PhysicalFilter, C1>, Plan>(
new TypePattern(PhysicalFilter.class, child1.pattern),
defaultPromise()
);
}
}
```
and then we don't have to add pattern for new operators.
this function utilizing jsr269 to do something in compile time, and utilizing antlr4 to analyze the code of `Operator`, then we can generate corresponding pattern.
pattern generate steps:
1. maven-compiler-plugin in the pom.xml will compile fe-core three terms. first term will compile `PatternDescribable.java` and `PatternDescribableProcessor.java`
2. second compile term will compile `PatternDescribableProcessPoint.java`, and enable annotation process `PatternDescribableProcessor`, PatternDescribableProcessor will receive the event and know that `PatternDescribableProcessPoint` class contains the `PatternDescribable` annotation.
3. `PatternDescribableProcessor` will not process `PatternDescribableProcessPoint`, but find all java file exists in `operatorPath` that specify in pom.xml, and then parse to Java AST(abstract syntax tree).
5. PatternDescribableProcessor collect java AST and use `PatternGeneratorAnalyzer` to analyze AST, find the child class file for `PlanOperator` then generate `GeneratedPatterns.java` by the AST.
6. third compile term will compile `GeneratedPatterns.java` and other java file.
1. Provide a FE conf to test the reliability in single replica case when tablet scheduling are frequent.
2. According to #6063, almost apply this fix on current code.
At present, Doris can only access the hadoop cluster with kerberos authentication enabled by broker, but Doris BE itself
does not supports access to a kerberos-authenticated HDFS file.
This PR hope solve the problem.
When create hive external table, users just specify following properties to access the hdfs data with kerberos authentication enabled:
```sql
CREATE EXTERNAL TABLE t_hive (
k1 int NOT NULL COMMENT "",
k2 char(10) NOT NULL COMMENT "",
k3 datetime NOT NULL COMMENT "",
k5 varchar(20) NOT NULL COMMENT "",
k6 double NOT NULL COMMENT ""
) ENGINE=HIVE
COMMENT "HIVE"
PROPERTIES (
'hive.metastore.uris' = 'thrift://192.168.0.1:9083',
'database' = 'hive_db',
'table' = 'hive_table',
'dfs.nameservices'='hacluster',
'dfs.ha.namenodes.hacluster'='n1,n2',
'dfs.namenode.rpc-address.hacluster.n1'='192.168.0.1:8020',
'dfs.namenode.rpc-address.hacluster.n2'='192.168.0.2:8020',

'hadoop.security.authentication'='kerberos',
'hadoop.kerberos.principal'='doris_test@REALM.COM',
'hadoop.kerberos.keytab'='/path/to/doris_test.keytab'
);
```
If you want to `select into outfile` to HDFS that kerberos authentication enable, you can refer to the following SQL statement：
```sql
select * from test into outfile "hdfs://tmp/outfile1"
format as csv
properties
(
'fs.defaultFS'='hdfs://hacluster/',
'dfs.nameservices'='hacluster',

The scalar expression is rewritten using the visitor pattern as a traversal.
In the abstract class ExpressionVisitor, which contains all predicate to rewrite.
We have provided a rewrite rules interface ExpressionRewriteRule, AbstractExpressionRewriteRule class implements the interface and expanded the ExpressionVisitor, if we want to realize an expression rewriting rules, Direct implementation AbstractExpressionRewriteRule provided in the method of traversing the predicate.
There are two rules to refer: NormalizeExpressionRule and SimplifyNotExprRule
Change the DatabaseIf APIs' return type to TableIf.
Use generics in DatabaseIf, to avoid changing the return type in Database.
Currently Database class use type Table, I'm try to avoid changing it to TableIf.
Because in this case, we need to change a lot of code.
When plan bucket shuffle join, we need to know left table bucket number.
Currently, we use tablet number directly based on the assumption that left table has only one partition.
But, when left table is colocated table, it could have more than one partition.
In this case, some data in right table will be dropped incorrectly and produce wrong result for query.
reproduce could follow regression test in PR.
