Netty: Conversion from ByteBuf to byte[] returns different length arrays for same data

[ga92yup]

Hi,

I am experiencing a behavior I would like to explain:
I am reading the same data from my local machine and in a network application as part of adding some code to Apache Pulsar.
The data is in ByteBuf format and needs to be converted to byte[] for further computation.
When reading the data locally, I use:
byte[] msgArray = buf.array();
The network code is as follows:
if(msg.hasArray()) {
msgArray = msg.array();
} else {
int readableBytes = msg.readableBytes();
msgArray = new byte[readableBytes];
int readerIndex = msg.readerIndex();
msg.getBytes(readerIndex, msgArray);
}
}
The same data locally has byte size of 259475, while in the network the size is 62290

Could you, help me understand what is happening here?

Thank you!

Regards,

Milena

I guess your server (client) didn't receive the complete data, maybe only 62290 bytes of data. Maybe you can try to assemble multiple message fragments in custom Decoder

Thanks a lot for your reply!

Also be sure you take readerIndex, arrayOffset and readableBytes into account when acting on the backing array.
