This documentation is a guide for using Paimon in Doris.
More details can be found in Apache Doris Website
Paimon currently supports Apache Doris 2.0.6 and above.
Use CREATE CATALOG
statement in Apache Doris to create Paimon Catalog.
Doris support multi types of Paimon Catalogs. Here are some examples:
-- HDFS based Paimon Catalog CREATE CATALOG `paimon_hdfs` PROPERTIES ( "type" = "paimon", "warehouse" = "hdfs://172.21.0.1:8020/user/paimon", "hadoop.username" = "hadoop" ); -- Aliyun OSS based Paimon Catalog CREATE CATALOG `paimon_oss` PROPERTIES ( "type" = "paimon", "warehouse" = "oss://paimon-bucket/paimonoss", "oss.endpoint" = "oss-cn-beijing.aliyuncs.com", "oss.access_key" = "ak", "oss.secret_key" = "sk" ); -- Hive Metastore based Paimon Catalog CREATE CATALOG `paimon_hms` PROPERTIES ( "type" = "paimon", "paimon.catalog.type" = "hms", "warehouse" = "hdfs://172.21.0.1:8020/user/zhangdong/paimon2", "hive.metastore.uris" = "thrift://172.21.0.44:7004", "hadoop.username" = "hadoop" ); -- Integrate with Aliyun DLF CREATE CATALOG paimon_dlf PROPERTIES ( 'type' = 'paimon', 'paimon.catalog.type' = 'dlf', 'warehouse' = 'oss://paimon-bucket/paimonoss/', 'dlf.proxy.mode' = 'DLF_ONLY', 'dlf.uid' = 'xxxxx', 'dlf.region' = 'cn-beijing', 'dlf.access_key' = 'ak', 'dlf.secret_key' = 'sk' );
See Apache Doris Website for more examples.
Query Paimon table with full qualified name
SELECT * FROM paimon_hdfs.paimon_db.paimon_table;
Switch to Paimon Catalog and query
SWITCH paimon_hdfs; USE paimon_db; SELECT * FROM paimon_table;
Read optimized for Primary Key Table
Doris can utilize the Read optimized feature for Primary Key Table(release in Paimon 0.6), by reading base data files using native Parquet/ORC reader and delta file using JNI.
Deletion Vectors
Doris(2.1.4+) natively supports Deletion Vectors(released in Paimon 0.8).
