Migrate to low-latency messaging conveniently

What is GIDL?

GIDL translates between the Interface Definition Languages (IDLs) of these messaging frameworks:

• Simple Binary Encoding (SBE) - low latency (LOLA)
• Google FlatBuffers - low latency (LOLA)
• Cap'n Proto (capnp) - low latency (LOLA)
• Apache Thrift - medium latency
• Google Protocol Buffers (ProtoBuf) - medium latency

Why GIDL?

Some reasons to use GIDL:

• Migrate to low-latency (LOLA) messaging frameworks conveniently
• Allow performance comparisons between different messaging frameworks
