Which Are The Two Types Of 'writes' In Hdfs? |
|
Answer» There are two TYPES of writes in HDFS: posted and non-posted write. Posted Write is when we write it and forget about it, without worrying about the acknowledgement. It is similar to our TRADITIONAL Indian post. In a Non-posted Write, we WAIT for the acknowledgement. It is similar to the today’s courier services. Naturally, non-posted write is more EXPENSIVE than the posted write. It is much more expensive, though both writes are asynchronous.
