# Hudi Table Engine
|
|
|
|
This engine provides a read-only integration with existing Apache [Hudi](https://hudi.apache.org/) tables in Amazon S3.
|
|
|
|
## Create Table
|
|
|
|
Note that the Hudi table must already exist in S3, this command does not take DDL parameters to create a new table.
|
|
|
|
``` sql
|
|
CREATE TABLE hudi_table
|
|
ENGINE = Hudi(url, [aws_access_key_id, aws_secret_access_key,])
|
|
```
|
|
|
|
**Engine parameters**
|
|
|
|
- `url` — Bucket url with the path to an existing Hudi table.
|
|
- `aws_access_key_id`, `aws_secret_access_key` - Long-term credentials for the [AWS](https://aws.amazon.com/) account user. You can use these to authenticate your requests. Parameter is optional. If credentials are not specified, they are used from the configuration file.
|
|
|
|
Engine parameters can be specified using [Named Collections](../../../operations/named-collections.md)
|
|
|
|
**Example**
|
|
|
|
```sql
|
|
CREATE TABLE hudi_table ENGINE=Hudi('http://mars-doc-test.s3.amazonaws.com/clickhouse-bucket-3/test_table/', 'ABC123', 'Abc+123')
|
|
```
|
|
|
|
Using named collections:
|
|
|
|
``` xml
|
|
<clickhouse>
|
|
<named_collections>
|
|
<hudi_conf>
|
|
<url>http://mars-doc-test.s3.amazonaws.com/clickhouse-bucket-3/</url>
|
|
<access_key_id>ABC123<access_key_id>
|
|
<secret_access_key>Abc+123</secret_access_key>
|
|
</hudi_conf>
|
|
</named_collections>
|
|
</clickhouse>
|
|
```
|
|
|
|
```sql
|
|
CREATE TABLE hudi_table ENGINE=Hudi(hudi_conf, filename = 'test_table')
|
|
```
