Update JdbcOutput.java to resolve JDBC append issue.
Alternatively, to remain more in line with FileSystemOutput.java and HiveOutput.java, code can similarly be modified as per below snippet:
[...]
for (Tuple2<MutationType, Dataset<Row>> plan : planned) {
MutationType mutationType = plan._1();
Dataset<Row> mutation = plan._2();
DataFrameWriter<Row> writer = mutation.write();
switch (mutationType) {
case INSERT:
writer = writer.mode(SaveMode.Append);
writer.jdbc(url, tableName, properties);
break;
default:
throw new RuntimeException("JDBC output does not support mutation type: " + mutationType);
[...]

Hello @jeremybeard, I am currently using Envelope for a project I am working on, and came across an issue while trying to append when using JDBC as an output, with an planner type of append. I have provided my solution as per this pull request, any feedback and review on the code change would be greatly appreciated. Best Regards, |

Update JdbcOutput.java to resolve JDBC append issue.
DataFrameWriter defaults to SaveMode.ErrorIfExists, not allowing for appending to an existing table.
Explicitly set SaveMode to Append.
