Doris Data Import Suggestions

This topic describes the technical suggestions for importing Doris data.

Data Import

[Optional] When Flink writes data to Doris in real time, set the checkpoint based on the data volume of each batch. If the data volume of each batch is too small, a large number of small files will be generated. The recommended value is 60s.
[Optional] Import data in batches at a low frequency. The average interval for importing a single table must be greater than 30s. Import 10000 to 100000 rows of data each time at a recommended interval of 60s.
