S3 Compatible Storage

Doris provides two ways to load files from S3 Compatible Storage:

• Use S3 Load to load S3 Compatible Storage files into Doris, which is an asynchronous load method.
• Use TVF to load S3 Compatible Storage files into Doris, which is a synchronous load method.

Caution

The S3 SDK uses the virtual-hosted style by default. However, some object storage systems may not enable or support virtual-hosted style access. In this case, we can add the use_path_style parameter to force the use of the path style.

load with S3 Load

Use S3 Load to import files on object storage. For detailed steps, please refer to the Broker Load Manual

Step 1: Prepare the data

Create a CSV file s3load_example.csv The file is stored on S3 Compatible Storage and its content is as follows:

1,Emily,25
2,Benjamin,35
3,Olivia,28
4,Alexander,60
5,Ava,17
6,William,69
7,Sophia,32
8,James,64
9,Emma,37
10,Liam,64

Step 2: Create a table in Doris

CREATE TABLE test_s3load(
    user_id            BIGINT       NOT NULL COMMENT "user id",
    name               VARCHAR(20)           COMMENT "name",
    age                INT                   COMMENT "age"
)
DUPLICATE KEY(user_id)
DISTRIBUTED BY HASH(user_id) BUCKETS 10;

Step 3: Load data using S3 Load

LOAD LABEL s3_load_2022_04_01
(
    DATA INFILE("s3://your_bucket_name/s3load_example.csv")
    INTO TABLE test_s3load
    COLUMNS TERMINATED BY ","
    FORMAT AS "CSV"
    (user_id, name, age)
)
WITH S3
(
    "provider" = "S3",
    "s3.endpoint" = "play.min.io:9000",  
    "s3.region" = "us-east-1",
    "s3.access_key" = "AKIAIOSFODNN7EXAMPLE",
    "s3.secret_key" = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY",
    "use_path_style" = "true"
)
PROPERTIES
(
    "timeout" = "3600"
);

Step 4: Check the imported data

SELECT * FROM test_s3load;

Results:

mysql> select * from test_s3load;
+---------+-----------+------+
| user_id | name      | age  |
+---------+-----------+------+
|       5 | Ava       |   17 |
|      10 | Liam      |   64 |
|       7 | Sophia    |   32 |
|       9 | Emma      |   37 |
|       1 | Emily     |   25 |
|       4 | Alexander |   60 |
|       2 | Benjamin  |   35 |
|       3 | Olivia    |   28 |
|       6 | William   |   69 |
|       8 | James     |   64 |
+---------+-----------+------+
10 rows in set (0.04 sec)

Load with TVF

Step 1: Prepare the data

Create a CSV file s3load_example.csv The file is stored on S3 Compatible Storage and its content is as follows:

1,Emily,25
2,Benjamin,35
3,Olivia,28
4,Alexander,60
5,Ava,17
6,William,69
7,Sophia,32
8,James,64
9,Emma,37
10,Liam,64

Step 2: Create a table in Doris

CREATE TABLE test_s3load(
    user_id            BIGINT       NOT NULL COMMENT "user id",
    name               VARCHAR(20)           COMMENT "name",
    age                INT                   COMMENT "age"
)
DUPLICATE KEY(user_id)
DISTRIBUTED BY HASH(user_id) BUCKETS 10;

Step 3: Load data using TVF

INSERT INTO test_s3load
SELECT * FROM S3
(
    "uri" = "s3://your_bucket_name/s3load_example.csv",
    "format" = "csv",
    "provider" = "S3",
    "s3.endpoint" = "play.min.io:9000",
    "s3.region" = "us-east-1",
    "s3.access_key" = "AKIAIOSFODNN7EXAMPLE",
    "s3.secret_key" = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY",
    "column_separator" = ",",
    "csv_schema" = "user_id:int;name:string;age:int",
    "use_path_style" = "true"
);

Step 4: Check the imported data

SELECT * FROM test_s3load;

Results:

mysql> select * from test_s3load;
+---------+-----------+------+
| user_id | name      | age  |
+---------+-----------+------+
|       5 | Ava       |   17 |

|       1 | Emily     |   25 |
|       4 | Alexander |   60 |
|       2 | Benjamin  |   35 |
|       3 | Olivia    |   28 |
|       6 | William   |   69 |
|       8 | James     |   64 |
