I spoke too soon and it actually still does not work.

I'm getting the following error in a simple Directory -> Trash workflow.

XML_PARSER_01 - Cannot obtain current reader position: com.streamsets.pipeline.lib.parser.DataParserException:
XML_PARSER_01 - Cannot obtain current reader position: ParseError at
[row,col]:[75393,26] Message: Reader exceeded the read limit '1048576'

I'm using a delimiter to chunk the input file but it does not fix the problem...

Worflow json and xml file available here:

If you do a preview, is it processing ANY records? If so, then the delimiter is working properly and you simply have an element greater than your max record size, starting at the position in the file indicated by the log line.

Good point. I was focused on the overall size of the XML file but the problem comes from an XML element which is 62395 lines long!!! Is there a way to tackle that problem other than changing the XML source file?

You can keep increasing the max record size to a sufficient value to accommodate even that element?

I can't increase above 2147483647, which is not enough unfortunately.

As a workaround, would it be possible to ignore such huge element instead of crashing the parsing?

I'm still looking for a solution on that problem.

For those who would like to see the problem in action, simply create an HTTPclient on the following: with XML parsing.

It should crash with a 'XML object exceeded maximum length' error.

[Edit] I finally managed to make it wotk by setting properly the parameters DataFactoryBuilder.OverRunLimit and such as:

Blockquote docker rm -f streamsets-dc-2; docker run -p 18630:18630 -v XXX -e SDC_JAVA_OPTS="-Dhttp.proxyHost=$PROXY_HOST -Dhttp.proxyPort=$PROXY_PORT -DDataFactoryBuilder.OverRunLimit=20485760" -e STREAMSETS_LIBRARIES_EXTRA_DIR=XXX -d --name ...
