## Usage example
-1. Example 1
-
- Export simple query results to the file `hdfs://path/to/result.txt`.
Specify the export format as CSV. Use `my_broker` and set kerberos
authentication information. Specify the column separator as `,` and the line
delimiter as `\n`.
-
- ```
- SELECT * FROM tbl
- INTO OUTFILE "hdfs://path/to/result_"
- FORMAT AS CSV
- PROPERTIES
- (
- "broker.name" = "my_broker",
- "broker.hadoop.security.authentication" = "kerberos",
- "broker.kerberos_principal" = "do...@your.com",
- "broker.kerberos_keytab" = "/home/doris/my.keytab",
- "column_separator" = ",",
- "line_delimiter" = "\n",
- "max_file_size" = "100MB"
- );
- ```
-
- If the result is less than 100MB, file will be: `result_0.csv`.
-
- If larger than 100MB, may be: `result_0.csv, result_1.csv, ...`.
-
-2. Example 2
-
- Export simple query results to the file `hdfs://path/to/result.parquet`.
Specify the export format as PARQUET. Use `my_broker` and set kerberos
authentication information.
-
- ```
- SELECT c1, c2, c3 FROM tbl
- INTO OUTFILE "hdfs://path/to/result_"
- FORMAT AS PARQUET
- PROPERTIES
- (
- "broker.name" = "my_broker",
- "broker.hadoop.security.authentication" = "kerberos",
- "broker.kerberos_principal" = "do...@your.com",
- "broker.kerberos_keytab" = "/home/doris/my.keytab",
-
"schema"="required,int32,c1;required,byte_array,c2;required,byte_array,c2"
- );
- ```
-
- If the exported file format is PARQUET, `schema` must be specified.
-
-3. Example 3
-
- Export the query result of the CTE statement to the file
`hdfs://path/to/result.txt`. The default export format is CSV. Use `my_broker`
and set hdfs high availability information. Use the default column separators
and line delimiter.
-
- ```
- WITH
- x1 AS
- (SELECT k1, k2 FROM tbl1),
- x2 AS
- (SELECT k3 FROM tbl2)
- SELEC k1 FROM x1 UNION SELECT k3 FROM x2
- INTO OUTFILE "hdfs://path/to/result_"
- PROPERTIES
- (
- "broker.name" = "my_broker",
- "broker.username"="user",
- "broker.password"="passwd",
- "broker.dfs.nameservices" = "my_ha",
- "broker.dfs.ha.namenodes.my_ha" = "my_namenode1, my_namenode2",
- "broker.dfs.namenode.rpc-address.my_ha.my_namenode1" =
"nn1_host:rpc_port",
- "broker.dfs.namenode.rpc-address.my_ha.my_namenode2" =
"nn2_host:rpc_port",
- "broker.dfs.client.failover.proxy.provider" =
"org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider"
- );
- ```
-
- If the result is less than 1GB, file will be: `result_0.csv`.
-
- If larger than 1GB, may be: `result_0.csv, result_1.csv, ...`.
-
-4. Example 4
-
- Export the query results of the UNION statement to the file
`bos://bucket/result.parquet`. Specify the export format as PARQUET. Use
`my_broker` and set hdfs high availability information. PARQUET format does not
need to specify the column separator and line delimiter.
-
- ```
- SELECT k1 FROM tbl1 UNION SELECT k2 FROM tbl1
- INTO OUTFILE "bos://bucket/result_"
- FORMAT AS PARQUET
- PROPERTIES
- (
- "broker.name" = "my_broker",
- "broker.bos_endpoint" = "http://bj.bcebos.com";,
- "broker.bos_accesskey" = "xxxxxxxxxxxxxxxxxxxxxxxxxx",
- "broker.bos_secret_accesskey" = "yyyyyyyyyyyyyyyyyyyyyyyyyy",
- "schema"="required,int32,k1;required,byte_array,k2"
- );
- ```
-
-5. Example 5
-
- Export simple query results to the file
`cos://${bucket_name}/path/result.txt`. Specify the export format as CSV.
- And create a mark file after export finished.
-
- ```
- select k1,k2,v1 from tbl1 limit 100000
- into outfile "s3a://my_bucket/export/my_file_"
- FORMAT AS CSV
- PROPERTIES
- (
- "broker.name" = "hdfs_broker",
- "broker.fs.s3a.access.key" = "xxx",
- "broker.fs.s3a.secret.key" = "xxxx",
- "broker.fs.s3a.endpoint" = "https://cos.xxxxxx.myqcloud.com/";,
- "column_separator" = ",",
- "line_delimiter" = "\n",
- "max_file_size" = "1024MB",
- "success_file_name" = "SUCCESS"
- )
- ```
-
- If the result is less than 1GB, file will be: `my_file_0.csv`.
-
- If larger than 1GB, may be: `my_file_0.csv, result_1.csv, ...`.
-
- Please Note:
- 1. Paths that do not exist are automatically created.
- 2. These parameters(access.key/secret.key/endpointneed) need to be
confirmed with `Tecent Cloud COS`. In particular, the value of endpoint does
not need to be filled in bucket_name.
-
-6. Example 6
-
- Use the s3 protocol to export to bos, and concurrent export is enabled.
-
- ```
- set enable_parallel_outfile = true;
- select k1 from tb1 limit 1000
- into outfile "s3://my_bucket/export/my_file_"
- format as csv
- properties
- (
- "AWS_ENDPOINT" = "http://s3.bd.bcebos.com";,
- "AWS_ACCESS_KEY" = "xxxx",
- "AWS_SECRET_KEY" = "xxx",
- "AWS_REGION" = "bd"
- )
- ```
-
- The final generated file prefix is `my_file_{fragment_instance_id}_`。
-
-7. Example 7
-
- Use the s3 protocol to export to bos, and enable concurrent export of
session variables.
-
- ```
- set enable_parallel_outfile = true;
- select k1 from tb1 order by k1 limit 1000
- into outfile "s3://my_bucket/export/my_file_"
- format as csv
- properties
- (
- "AWS_ENDPOINT" = "http://s3.bd.bcebos.com";,
- "AWS_ACCESS_KEY" = "xxxx",
- "AWS_SECRET_KEY" = "xxx",
- "AWS_REGION" = "bd"
- )
- ```
-
- **But because the query statement has a top-level sorting node, even if
the query is enabled for concurrently exported session variables, it cannot be
exported concurrently.**
