• 1,000 write per

second

• Parsing, locking,

logging, threads …

Evolution

NoSQL – Disadvantage

• Can’t be use for analytics, reporting …

• Lack of relation from one key to another

• Packing and un-packing of each key

• Need whole value from the key; to

read/write any partial information

Comparison

• Fast enough

• Disk based

• 4,000 OPS

• 1,000 write/s

MySQL

• Super fast

• RAM based

• 50,000 OPS

• Writes are fast as
