   <h3>INTRO</h3>

   <p>FS is a <b>filesystem</b> backend implementation for KVS.

      Put the {dba,kvs_fs} property for the kvs application in your sys.config.</p>

   <br />



   <h3>EXAMPLES</h3>



   <blockquote>All examples can be executed in Erlang REPL. Only

     requirement is to have kvs set in dependencies and kvs application

     started.</blockquote>

   

   <p>Create a new kvs_fs table called test. When executed, this

     function will create a new directory called test under data

     directory in the current workspace.</p>

   

   <figure><code>

       kvs_fs:create_table(test, []).

       % will return:

       % ok

   </code></figure>



   <p>Put a new key/value in table test. When executed, a new file is

     created under test directory. Its name is based on the sha1 of

     the key encoded in base64.</p>



   <figure><code>

       Table = test.

       Key = key.

       Value = <<"my_value">>.

       kvs_fs:put({test, Key, Value}).

       % will return:

       % ok

   </code></figure>



   <p>Get a key from value test.</p>



   <figure><code>

       kvs_fs:get(test, key).

       % will return:

       % {ok, {test, key, <<"my_value">>}}

   </code></figure>





   <p>Delete a key</p>
