Re: How to properly close igfs file after appending it
Hi, Prashant,
are you trying to append concurrently from several streams?
The situation you observe means that you're trying to append a file that is
currently open for writing in another output stream. (When a file is open
for append, a special lock is placed to the file meta information in meta
cache to prevent concurrent file appending.)
You should not open any transactions, IGFS implementation creates all
necessary transactions for you.
If you're appending the file with many small portions of data, it would be
much more efficient use one output stream than to open and close a new
stream for each portion.

What do you mean by not open any transactions?
