Build

    $ rebar3 compile

Create a cdb

    A = cdb:make_start("foo.cdb"),
    B = cdb:make_add(A, <<199919:64>>, <<"ccc">>),
    C = cdb:make_add(B, <<"aa">>, <<"bbb">>),
    ok = cdb:make_finish(C),
    ?assertEqual({<<199919:64>>, <<"ccc">>}, cdb:find("foo.cdb", <<199919:64>>)),
    ?assertEqual({<<"aa">>, <<"bbb">>}, cdb:find("foo.cdb", <<"aa">>)).

Find a key

    A = cdb:make_start("foo.cdb"),
    B = cdb:make_add(A, <<"aa">>, <<"bbb">>),
    ok = cdb:make_finish(B),
    ?assertEqual({<<"aa">>, <<"bbb">>}, cdb:find("foo.cdb", <<"aa">>)).
