title: Equivalent of pgpool-II for MySQL
body: <p>Is there any tools which is equivalent to <strong><a href="http://pgpool.projects.postgresql.org/pgpool-II/doc/pgpool-en.html" rel="nofollow">pgpool-II</a></strong> (which is for PostgreSQL) for MySQL db?</p>
  
  <p>Of particular importance for me is the feature - Load Balalce</p>
  
  <h1>Load Balance</h1>
  
  <blockquote>
    <p>If a database is replicated, executing
    a SELECT query on any server will
    return the same result. pgpool-II
    takes an advantage of the replication
    feature to reduce the load on each
    PostgreSQL server by distributing
    SELECT queries among multiple servers,
    improving system's overall throughput.
    At best, performance improves
    proportionally to the number of
    PostgreSQL servers. Load balance works
    best in a situation where there are a
    lot of users executing many queries at
    the same time.</p>
