S3 #

If you have already configured s3 access through Flink (Via Flink FileSystem), here you can skip the following configuration.

Put paimon-s3-0.8.2.jar into lib directory of your Flink home, and create catalog:

CREATE CATALOG my_catalog WITH (
    'type' = 'paimon',
    'warehouse' = 's3://<bucket>/<path>',
    's3.endpoint' = 'your-endpoint-hostname',
    's3.access-key' = 'xxx',
    's3.secret-key' = 'yyy'
);

If you have already configured s3 access through Spark (Via Hadoop FileSystem), here you can skip the following configuration.

Place paimon-s3-0.8.2.jar together with paimon-spark-0.8.2.jar under Spark’s jars directory, and start like

spark-sql \ 
  --conf spark.sql.catalog.paimon=org.apache.paimon.spark.SparkCatalog \
  --conf spark.sql.catalog.paimon.warehouse=s3://<bucket>/<path> \
  --conf spark.sql.catalog.paimon.s3.endpoint=your-endpoint-hostname \
  --conf spark.sql.catalog.paimon.s3.access-key=xxx \
  --conf spark.sql.catalog.paimon.s3.secret-key=yyy

If you have already configured s3 access through Hive ((Via Hadoop FileSystem)), here you can skip the following configuration.

NOTE: You need to ensure that Hive metastore can access s3.

Place paimon-s3-0.8.2.jar together with paimon-hive-connector-0.8.2.jar under Hive’s auxlib directory, and start like

SET paimon.s3.endpoint=your-endpoint-hostname;
SET paimon.s3.access-key=xxx;
SET paimon.s3.secret-key=yyy;

And read table from hive metastore, table can be created by Flink or Spark, see Catalog with Hive Metastore

SELECT * FROM test_table;
SELECT COUNT(1) FROM test_table;

Paimon use shared trino filesystem as basic read and write system.

Please refer to Trino S3 to config s3 filesystem in trino.
