Java heap space: java.lang.OutOfMemoryError: Java heap space

[e-sociaux]

Hello all,

Why I got out of memory during processing the file with ExecuteGroovyScript?

 

The size of file could be reach a maxsize to 190Mo

Error : ExecuteGroovyScript[id=07e5314d-b20a-1076-882b-54b44baca66d] java.lang.OutOfMemoryError: Java heap space: java.lang.OutOfMemoryError: Java heap space

The groovy is very simple : 



        // get data from flowfile

        text = IOUtils.toString(inputStream, StandardCharsets.UTF_8)



        // add timestamp in each line in the text/flowfile

        text = text.replaceAll(/^/, "\"timestamp\":\"$timestamp\",")

        

        // write back to the flowfile

        outputStream.write(text.getBytes(StandardCharsets.UTF_8))



Could you help me to process if it is not the good way to do this thing ?



Thanks



Minh
