-Determine AVRO message size
Golikov, Vassili 2013-07-19, 14:40
Hi AVRO Dev Team
We intend to use AVRO as conversion tool to send messages between C++, .NET, and JAVA applications, where actual transport is done via TCP. I am looking for a method to get actual AVRO message size after encoding is done.
// some function here
// framing code here
// very short and simple message just one integer
unsigned int message = 12345;
std::auto_ptr<avro::OutputStream> out = avro::memoryOutputStream(100);
avro::EncodePtr e = avro::binaryEncoder();
std::size_t length = out->bytesCount(); // returns 100 bytes instead of 4
std::auto_ptr<avro::InputStream> in = avro::memoryInputStream(*out);
sr.readBytes(&buffer[offset], length); // will read a 100 bytes instead of 4
socket_send(socket_id, buffer, length + offset); // will send 100 bytes instead of 4
Could you advise how one can figure out exact AVRO message length? It seems currently it is just a number of buffers product buffer length. Our messages are small and do not exceed 128 bytes.
