Join Stack Overflow to learn, share knowledge, and build your career. Insert, on duplicate update in PostgreSQL? Kudu supports a number of DML type operations, several of which are included in the Spark on Kudu integration. The goals for Kudu are fast columnar scans, low latency updates and low performance variance. Kudu tables require a unique primary key for each row. In most relational databases, if you try to insert a row that has already been inserted, the insertion will fail because the primary key would be duplicated. How true is this observation concerning battle? KUDU-1577 Spark insert-ignore is significantly slower that upsert.
