Tomo Suzuki updated BEAM-8865:
------------------------------
Description:
The doc says
!v1YuuuT2o2i.png!
However, I had to modify the code to below:
{noformat}
p.apply("ReadLines",
FileIO.match().filepattern("hdfs:///foo/bar/*.gz"))
.apply(FileIO.readMatches().withCompression(GZIP))
.apply(MapElements
// uses imports from TypeDescriptors
.into(kvs(strings(), strings()))
.via((ReadableFile f) -> {
try {
return KV.of(
f.getMetadata().resourceId().toString(),
f.readFullyAsUTF8String());
} catch (IOException ex) {
throw new RuntimeException("Failed to read the file", ex);
}
}))
{noformat}
