erlav

High performance avro encoding/decoding NIF-based library

Build

$ rebar3 compile
$ rebar3 eunit

Usage

SchemaId = erlav_nif:erlav_init(<<"priv/tschema2.avsc">>),
Term = #{
        <<"intField">> => 789,
        <<"longField">> => 2989898111,
        <<"doubleField">> => 11.2345,
        <<"floatField">> => 23.12,
        <<"boolField">> => true,
        <<"stringField">> => <<"asdadasdasdasd3453534dfgdgd123456789">>,
        <<"bytesField">> => <<1,99,57,127,0,56>>
},

% Encode Term to avro format
Ret = erlav_nif:erlav_encode(SchemaId, Term),

% Decode data in avro format to erlang term
DecodedTerm = erlav_nif:erlav_decode_fast(SchemaId, Ret)

Performance

run erlang shell

erl -pa _build/default/lib/*/ebin

run performance test ( it will generate report at the end )

erlav_perf:all_tests().
