title: What does "fixed_len_byte_array" mean?
body: <p>I'm using the parquet file. I've found that parquet file has multiple data types, such as <code>int64,int32,boolean,binary,float,double,int96 and fixed_len_byte_array</code>.</p>
  
  <p>I know <code>int64,int32,int96,boolean,binary,float and double</code>. But I can't understand <code>‘fixed_len_byte_array’</code>.</p>
