About Apache Doris
Apache Doris is an open-source analytical database for real-time reporting, interactive SQL analytics, and data warehousing.
SQL access to streaming tables
The Fluss Catalog in Doris 5.0 exposes Fluss log and primary-key tables to SQL clients and BI tools without an intermediate ETL job. For primary-key tables, Doris combines snapshots with subsequent changes to return the latest state of each key.
Combining lake history with fresh updates
For tables tiered into Paimon, a union read combines historical lake data with the newer records still in Fluss. Doris scans lake files through its native readers and reads the remaining log tail through the Fluss client, preserving a unified view of the table.
Bringing Fluss into federated analytics
Queries can join Fluss tables with Doris internal tables or other catalogs, including Hive, Iceberg, Paimon, and JDBC sources. Column and partition pruning reduce unnecessary reads, while query profiles expose which read paths were used.
