> > @yyh2954360585 JDBC is slow and put lot of load on source system. So full query a full query on large table can cause high load or even downtime to the database server. You can set the value of source-limit according to your dataset and requirement. You can even set it to a very high value. > > If I set source limit=1000, then I can only extract 1000 pieces of data from the source table, which is not reasonable. Because it has no offset https://github.com/apache/hudi/blob/ba5ab8ca46863a67023e7172fb16a9a36d3b5acb/hudi-utilities/src/main/java/org/apache/hudi/utilities/sources/JdbcSource.java#L239-L252 -- This is an automated message from the Apache Git Service.
