The new Doris Catalog replaces the previous method of accessing external tables in remote Doris clusters via JDBC Catalog. 1. It retrieves metadata of Doris external tables through HTTP APIs. 2. The metadata information for Doris external tables is more accurate, fully capturing various metadata from remote cluster tables, such as primary keys, bucketing keys, and native Doris data types. 3. The underlying implementation uses ADBC to communicate with the remote Doris cluster, achieving approximately 4 times higher transmission performance compared to the single-node JDBC Catalog. 4. It supports concurrent retrieval of Arrow response results from the remote Doris cluster, with transmission performance scaling linearly as the cluster size increases. -- This is an automated message from the Apache Git Service.
