Hi Camel,
Is there a way to unzip huge file by using streaming? I got OutOfMemoryError if
the uncompressed file size (4GB). I tried to use custom unzip processor with
streaming and it works fine.
Very appreciated if you have a solution.
/* Unzip .gz file route */
from("file:...")
.unmarshal().gzipDeflater()
.to("file:...");
/* Unzip .gz file using custom processor */
from("file:...")
.processor("unzipProcessor");
/* unzipProcessor -> 9 seconds to unzip for uncompressed file (4GB) */
byte[] buffer = new byte[102400];
int length;
FileInputStream fis = new FileInputStream(fileName);
GZIPInputStream gzis = new GZIPInputStream(fis);
FileOutputStream fos = new FileOutputStream("d:\\temp\\test.json");
while ((length = gzis.read(buffer)) > 0) {
fos.write(buffer, 0, length);
}
