Apache Doris provides multiple ways to import data, including StreamLoad, HdfsLoad (gradually replacing BrokerLoad), RoutineLoad, MySQLLoad, and others. StreamLoad is the most commonly used method, as many data synchronization tools like Flink, Spark, and DataX use it under the hood.

Since StreamLoad is the underlying mechanism for Flink Doris Connector, Spark Doris Connector, and DataX, most data import issues tend to occur with StreamLoad. This article will discuss common import errors and their solutions.
