# join hint using document
|
||||
|
||||
In the database, "Hint" is an instruction that instructs the query optimizer to execute a plan. By embedding hints in SQL statements, you can influence the optimizer's decision to select the desired execution path. Here is a background example using Hint:
|
||||
|
||||
Suppose you have a table that contains a large amount of data, and you know that in some specific circumstances, the join order of the tables in a query may affect query performance. Leading Hint allows you to specify the order of table joins that you want the optimizer to follow.
|
||||
|
||||
For example, consider the following SQL query:
|
||||
```sql
|
||||
mysql> explain shape plan select * from t1 join t2 on t1.c1 = c2;
|
||||
+-------------------------------------------+
|
||||

|
||||
| ----------PhysicalOlapScan[t1] |
|
||||
+-------------------------------------------+
|
||||
7 rows in set (0.06 sec)
|
||||
```
|
||||
|
||||
In the above example, when the execution efficiency is not ideal, we want to adjust the join order without changing the original sql so as to avoid affecting the user's original scene and achieve the purpose of tuning. We can use leading to arbitrarily change the join order of tableA and tableB. For example, it could be written like:
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t2 t1) */ * from t1 join t2 on c1 = c2;

|
||||
```
|
||||
In this example, the Hint /*+ leading(t2 t1) */ is used. This Hint tells the optimizer to use the specified table (t2) as the driver table in the execution plan, before (t1).
|
||||
|
||||
This document mainly describes how to use join related hints in Doris: leading hint, ordered hint and distribute hint
|
||||
# Leading hint
|
||||
Leading Hint is used to guide the optimizer in determining the join order of the query plan. In a query, the join order of the tables can affect query performance. Leading Hint allows you to specify the order of table joins that you want the optimizer to follow.
|
||||
|
||||
In doris, the syntax is /*+LEADING(tablespec [tablespec]... ) */,leading is surrounded by "/*+" and "*/" and placed directly behind the select in the select statement. Note that the '/' after leading and the selectlist need to be separated by at least one separator such as a space. At least two more tables need to be written before the leadinghint is justified. And any join can be bracketed to explicitly specify the shape of the joinTree. Example:
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t2 t1) */ * from t1 join t2 on c1 = c2;

```
|
||||
- If the leadinghint fails to take effect, the explain process will be used to generate the leadinghint. The EXPLAIN process will display whether the Leadinghint takes effect. There are three types of hints:
|
||||
|
||||
- Used: leading hint takes effect normally
|
||||
|
||||
- Unused: Unsupported cases include the feature that the leading specified join order is not equivalent to the original sql or is not supported in this version (see restrictions).
|
||||
|
||||
- SyntaxError: indicates leading hint syntax errors, such as failure to find the corresponding table
|
||||
|
||||
- The leading hint syntax creates a left deep tree by default. For example, select /*+ leading(t1 t2 t3) */ * from t1 join t2 on... Specify by default
|
||||
```sql
|
||||
join
|
||||
/ \
|
||||
join t3
|
||||
/ \
|
||||
t1 t2
|
||||
|
||||
mysql> explain shape plan select /*+ leading(t1 t2 t3) */ * from t1 join t2 on c1 = c2 join t3 on c2=c3;

|

|

- When a view is used as an alias in joinReorder, the corresponding view can be specified as the leading parameter. Example:
|
||||
```sql
|

mysql> explain shape plan select /*+ leading(alias t1) */ count(*) from t1 join (select c2 from t2 join t3 on t2.c2 = t3.c3) as alias on t1.c1 = alias.c2;

```
|
||||
## Basic cases
|
||||
（Note that the column name is related to the table name, for example: only t1 has c1 field, the following example will write t1.c1 directly to c1 for simplicity）
|
||||
```sql
|
||||
CREATE DATABASE testleading;
|
||||
USE testleading;
|
||||
|
||||
create table t1 (c1 int, c11 int) distributed by hash(c1) buckets 3 properties('replication_num' = '1');
|
||||
create table t2 (c2 int, c22 int) distributed by hash(c2) buckets 3 properties('replication_num' = '1');
|
||||
create table t3 (c3 int, c33 int) distributed by hash(c3) buckets 3 properties('replication_num' = '1');
|
||||
create table t4 (c4 int, c44 int) distributed by hash(c4) buckets 3 properties('replication_num' = '1');
|
||||
|
||||
```
|
||||
For a simple example, when we need to exchange the join order of t1 and t2, we only need to add leading(t2 t1) before it, which will be used in the explain

|
||||
### Left deep tree
|
||||
leading generates a left deep tree by default when we don't use any parentheses
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t1 t2 t3) */ * from t1 join t2 on t1.c1 = c2 join t3 on c2 = c3;

|
||||
```
|
||||
### Right deep tree
|
||||
When we want to make the shape of the plan into a right deep tree, bushy tree or zigzag tree, we only need to add curly brackets to limit the shape of the plan, instead of using swap to adjust from the left deep tree step by step like oracle.
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t1 {t2 t3}) */ * from t1 join t2 on t1.c1 = c2 join t3 on c2 = c3;

## Non-inner join：
|
||||
When non-inner-joins are encountered, such as Outer join or semi/anti join, leading hint automatically deduces the join mode of each join according to the original sql semantics. If leading hints that differ from the original sql semantics or cannot be generated, they are placed in unused, but do not affect the generation of the normal flow of the plan.
|
||||
|
||||
Here are examples of things that can't be exchanged:
|
||||
-------- test outer join which can not swap
|
||||
-- t1 leftjoin (t2 join t3 on (P23)) on (P12) != (t1 leftjoin t2 on (P12)) join t3 on (P23)
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t1 {t2 t3}) */ * from t1 left join t2 on c1 = c2 join t3 on c2 = c3;

## View
|
||||
In the case of aliases, you can specify the alias as a complete subtree with joinOrder generated from text order.
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(alias t1) */ count(*) from t1 join (select c2 from t2 join t3 on t2.c2 = t3.c3) as alias on t1.c1 = alias.c2;

|
||||
- The current version supports only one leadingHint. If leadinghint is used with a subquery, the query will report an error. Example (This example explain will report an error, but will follow the normal path generation plan) :
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(alias t1) */ count(*) from t1 join (select /*+ leading(t3 t2) */ c2 from t2 join t3 on t2.c2 = t3.c3) as alias on t1.c1 = alias.c2;

# OrderedHint
|
||||
- Using ordered hint causes the join tree to be fixed in shape and displayed in text order
|
||||
- The syntax is /*+ ORDERED */,leading is surrounded by "/*+" and "*/" and placed directly behind the select in the select statement, for example：
|
||||
```sql
|
||||
explain shape plan select /*+ ORDERED */ t1.c1 from t2 join t1 on t1.c1 = t2.c2 join t3 on c2 = c3;
|
||||
join
|
||||
/ \
|
||||
join t3
|
||||
/ \
|
||||
t2 t1
|
||||
|
||||
mysql> explain shape plan select /*+ ORDERED */ t1.c1 from t2 join t1 on t1.c1 = t2.c2 join t3 on c2 = c3;

# DistributeHint
|
||||
- Currently, only the distribute Type of the right table can be specified, and only two types are available: [shuffle] and [broadcast]. They are written before the right join table. Brackets and /*+ */ are allowed
|
||||
|
||||
- Currently you can use any DistributeHint
|
||||
|
||||
- When a DistributeHint whose plan cannot be correctly generated is not displayed, it takes effect based on maximum effort. Finally, the distribute mode that is displayed is mainly explained
|
||||
|
||||
- The current distribute version is not combined with leading. It takes effect only when the table specified in DISTRIBUTE is on the right of join.
|
||||
|
||||
- Mixed with ordered, the text order is used to set the join order and then specify the expected distribute mode in the corresponding join. Example:
|
||||
|
||||
Before use distribute hint:
|
||||
```sql
|

|
||||
- the Explain shape plan will display inside distribute operator related information, including DistributionSpecReplicated said the operator will be corresponding data into a copy of all be node, DistributionSpecGather indicates that data is gathered to fe nodes, and DistributionSpecHash indicates that data is dispersed to different be nodes according to a specific hashKey and algorithm.
|
||||
# To be supported
|
||||
- leadingHint indicates that the current query cannot be mixed with the subquery after it is promoted. A hint is required to control whether the subquery can be unnested
|
||||
|
||||
- A new distributeHint is needed for better and more complete control of the distribute operator
|
||||
|
||||
- Use leadingHint and distributeHint together to determine the shape of a join

# join hint 使用文档
|
||||
# 背景
|
||||
在数据库中，"Hint" 是一种用于指导查询优化器执行计划的指令。通过在SQL语句中嵌入Hint，可以影响优化器的决策，以选中期望的执行路径。以下是一个使用Hint的背景示例：
|
||||
假设有一个包含大量数据的表，而你知道在某些特定情况下，在一个查询中，表的连接顺序可能会影响查询性能。Leading Hint允许你指定希望优化器遵循的表连接的顺序。
|
||||
例如，考虑以下SQL查询：
|
||||
```sql
|
||||
mysql> explain shape plan select * from t1 join t2 on t1.c1 = c2;
|
||||
+-------------------------------------------+
|
||||

|
||||
| ----------PhysicalOlapScan[t1] |
|
||||
+-------------------------------------------+
|
||||
7 rows in set (0.06 sec)
|
||||
```
|
||||
|
||||
在上述例子里面，在执行效率不理想的时候，我们希望调整下join顺序而不改变原始sql以免影响到用户原始场景且能达到调优的目的。我们可以使用leading任意改变tableA和tableB的join顺序。例如可以写成：
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t2 t1) */ * from t1 join t2 on c1 = c2;
|
||||

```
|
||||
在这个例子中，使用了 /*+ leading(t2 t1) */ 这个Hint。这个Hint告诉优化器在执行计划中使用指定表（t2）作为驱动表，并置于(t1)之前。
|
||||
本文主要阐述如何在Doris里面使用join相关的hint：leading hint、ordered hint 和 distribute hint
|
||||
# Leading hint使用说明
|
||||
Leading Hint 用于指导优化器确定查询计划的连接顺序。在一个查询中，表的连接顺序可能会影响查询性能。Leading Hint允许你指定希望优化器遵循的表连接的顺序。
|
||||
在doris里面，其语法为 /*+LEADING( tablespec [ tablespec ]... ) */,leading由"/*+"和"*/"包围并置于select语句里面 select的正后方。注意，leading 后方的 '/' 和selectlist需要隔开至少一个分割符例如空格。至少需要写两个以上的表才认为这个leadinghint是合理的。且任意的join里面可以用大括号括号起来，来显式地指定joinTree的形状。例：
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t2 t1) */ * from t1 join t2 on c1 = c2;
|
||||

|
||||
- 当leadinghint不生效的时候会走正常的流程生成计划，explain会显示使用的hint是否生效，主要分三种来显示：
|
||||
- Used：leading hint正常生效
|
||||
- Unused： 这里不支持的情况包含leading指定的join order与原sql不等价或本版本暂不支持特性（详见限制）
|
||||
- SyntaxError： 指leading hint语法错误，如找不到对应的表等
|
||||
- leading hint语法默认造出来左深树，例：select /*+ leading(t1 t2 t3) */ * from t1 join t2 on...默认指定出来
|
||||
```sql
|
||||

|

|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(alias t1) */ count(*) from t1 join (select c2 from t2 join t3 on t2.c2 = t3.c3) as alias on t1.c1 = alias.c2;

|
||||
## 基本用例
|
||||
（注意这里列命名和表命名相关，例：只有t1中有c1字段，后续例子为了简化会将 t1.c1 直接写成 c1）
|
||||
```sql
|
||||
CREATE DATABASE testleading;
|
||||
USE testleading;
|
||||
|
||||
create table t1 (c1 int, c11 int) distributed by hash(c1) buckets 3 properties('replication_num' = '1');
|
||||
create table t2 (c2 int, c22 int) distributed by hash(c2) buckets 3 properties('replication_num' = '1');
|
||||
create table t3 (c3 int, c33 int) distributed by hash(c3) buckets 3 properties('replication_num' = '1');
|
||||
create table t4 (c4 int, c44 int) distributed by hash(c4) buckets 3 properties('replication_num' = '1');
|
||||
|
||||
```
|
||||
举个简单的例子，当我们需要交换t1和t2的join顺序的时候只需要在前面加上leading(t2 t1)即可，explain的时候会
|
||||
显示是否用上了这个hint。
|
||||

若leading hint有语法错误，explain的时候会在syntax error里面显示相应的信息，但是计划能照常生成，只不过没有使用leading而已
|

|

## 扩展场景
|
||||
### 左深树
|
||||
当我们不使用任何括号的情况下leading会默认生成左深树
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t1 t2 t3) */ * from t1 join t2 on t1.c1 = c2 join t3 on c2 = c3;

|
||||
```
|
||||
### 右深树
|
||||
当我们想将计划的形状做成右深树或者bushy树或者zigzag树的时候，只需要加上大括号来限制plan的形状即可，不需要像oracle一样用swap从左深树一步步调整。
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t1 {t2 t3}) */ * from t1 join t2 on t1.c1 = c2 join t3 on c2 = c3;

|

## Non-inner join：
|
||||
当遇到非inner-join的时候，例如Outer join或者semi/anti join的时候，leading hint会根据原始sql语义自动推导各个join的join方式。若遇到与原始sql语义不同的leading hint或者生成不了的情况则会放到unused里面，但是不影响计划正常流程的生成。
|
||||
下面是不能交换的例子：
|
||||
-------- test outer join which can not swap
|
||||
-- t1 leftjoin (t2 join t3 on (P23)) on (P12) != (t1 leftjoin t2 on (P12)) join t3 on (P23)
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(t1 {t2 t3}) */ * from t1 left join t2 on c1 = c2 join t3 on c2 = c3;

explain shape plan select * from t1 where exists (select c2 from t2);
|

```
|
||||
## View
|
||||
遇到别名的情况，可以将别名作为一个完整的子树进行指定，子树里面的joinOrder由文本序生成。
|
||||
```sql
|
||||

## 与ordered混合使用
|
||||
当与ordered hint混合使用的时候以ordered hint为主，即ordered hint生效优先级高于leading hint。例：
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ ORDERED LEADING(t1 t2 t3) */ t1.c1 from t2 join t1 on t1.c1 = t2.c2 join t3 on c2 = c3;

|

```
|
||||
## 使用限制
|
||||
- 当前版本只支持使用一个leadingHint。若和子查询同时使用leadinghint的话则查询会报错。例（这个例子explain会报错，但是会走正常的路径生成计划）：
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ leading(alias t1) */ count(*) from t1 join (select /*+ leading(t3 t2) */ c2 from t2 join t3 on t2.c2 = t3.c3) as alias on t1.c1 = alias.c2;

# OrderedHint 使用说明
|
||||
- 使用ordered hint会让join tree的形状固定下来，按照文本序来显示
|
||||
- 语法为 /*+ ORDERED */,leading由"/*+"和"*/"包围并置于select语句里面 select的正后方，例：
|
||||
explain shape plan select /*+ ORDERED */ t1.c1 from t2 join t1 on t1.c1 = t2.c2 join t3 on c2 = c3;
|
||||
join
|
||||
/ \
|
||||
join t3
|
||||
/ \
|
||||
t2 t1
|
||||
|
||||
```sql
|
||||
mysql> explain shape plan select /*+ ORDERED */ t1.c1 from t2 join t1 on t1.c1 = t2.c2 join t3 on c2 = c3;

# DistributeHint 使用说明
|
||||
- 目前只能指定右表的distribute Type 而且只有[shuffle] 和 [broadcast]两种，写在join右表前面且允许中括号和/*+ */两种写法
|
||||
- 目前能使用任意个DistributeHint
|
||||
- 当遇到无法正确生成计划的 DistributeHint，没有显示，按最大努力生效，最后以explain显示的distribute方式为主
|
||||
- 当前版本暂不与leading混用，且当distribute指定的表位于join右边才可生效。
|
||||
- 多与ordered混用，利用文本序把join顺序固定下来，然后再指定相应的join里面我们预期使用什么样的distribute方式。例：
|
||||
使用前：
|
||||

|

- Explain shape plan里面会显示distribute算子相关的信息，其中DistributionSpecReplicated表示该算子将对应的数据变成所有be节点复制一份，DistributionSpecGather表示将数据gather到fe节点，DistributionSpecHash表示将数据按照特定的hashKey以及算法打散到不同的be节点。
|
||||
# 待支持
|
||||
- leadingHint待支持子查询解嵌套指定，当前和子查询提升以后不能混用，需要有hint来控制是否可以解嵌套
|
||||
- 需要新的distributeHint来更好且更全面地控制distribute算子
|
||||
- 混合使用leadingHint与distributeHint来共同确定join的形状
