title: What is binlog in mysql?
body: <p>I've set mysql parameter innodb_flush_log_at_trx_commit=0. It means that mysql flushes transactions to HDD 1 time per second. Is it true that if mysql will fail with this flush (because of power off) i will lose my data from these transactions. Or mysql will save them in data file (ibdata1) after each transaction regardless of binlog flush?</p>
  
  <p>Thanks.</p>
