Hi,
When i tried to use
{ok, File} = luwak_file:create(Riak, <<"file1">>, dict:new()),
Size = luwak_file:length(Riak, File),
io:format("Size is ~p bytes~n", [Size]),
{ok, _, File1} = luwak_io:put_range(Riak, File, 0, <<"1234567890">>),
Size1 = luwak_file:length(Riak, File1),
io:format("Size is ~p bytes~n", [Size1]),
%%create this file again
{ok, File2} = luwak_file:create(Riak, <<"file1">>, dict:new()),
Size2 = luwak_file:length(Riak, File2),
io:format("Size is ~p bytes~n", [Size2]),
%%write data at pos 100 which is invalid offset, but it works, why?
{ok, _, File3} = luwak_io:put_range(Riak, File2, 100, <<"abcdefg">>),
Size3 = luwak_file:length(Riak, File3),
io:format("Size is ~p bytes~n", [Size3]).
result:
Size is 0 bytes
Size is 10 bytes
Size is 10 bytes
Size is 107 bytes
ok
I tried many times and found seems like as long as i did these operation
using the same Riak connection, it will show results above. but when i used
another Riak connection({ok, Riak} = riak:client_connect('riak@127.0.0.1').
), it will truncate file contents. Is this the supposed result?
Best regards
Fisher
