01 Important update
1.Kubernetes integration
Supports the deployment of AMS and Optimizer through Kubernetes. For more details, please refer to the article "Amoro 0.6.0 Preview, Comprehensive Adaptation to Kubernetes and S3" .
2. More friendly integration with S3
When registering the catalog, you can choose that the Storage is S3 and supports the AK/SK verification system.
3. Paimon format support
Apache Paimon is a real-time data lake platform with high-speed data ingestion, change log tracking and efficient real-time analysis.
Apache paimon ：https://paimon.apache.org/
- Support registration of Paimon catalog on the Catalogs page.
- After registering the catalog, you can view the Schema, Properties, Files, Snapshots, Optimizing, Operations and other information of the table on the Tables page.
- Spark sql supported by paimon can be executed in the Terminal interface.
4. Partition and file expiration
Now you only need to perform some simple configurations on the table to enable the function of automatically expiring files or partitions in the table based on time, such as:
CREATE TABLE IF NOT EXISTS user (
id INT,
name string,
ts TIMESTAMP
) USING iceberg
PARTITIONED BY (days(ts));
ALTER TABLE user SET TBLPROPERTIES (
'data-expire.enabled' = 'true',
'data-expire.level' = 'partition',
'data-expire.field' = 'ts',
'data-expire.retention-time' = '30d'
);
The above example enables the automatic expiration function of partitions on the user table, and AMS will automatically eliminate partitions that are older than 30 days. For more information about automatic expiration of partitions and files, please refer to the latest user manual: https://amoro.netease.com/docs/latest/using-tables/#configure-data-expiration .
5.Mixed Format supports ORC file format
Mixed Format Users can set the file storage format to ORC format.
6.Mixed Format supports Flink-1.16 and Flink-1.17
Support for Flink-1.12 and Flink-1.14 has been removed, and support for Flink-1.16 and Flink-1.17 has been added.
7. Optimize the memory usage of Position Delete
Reduces the memory consumption caused by indexing Iceberg's position-delete data during the Self-Optimizing process.
