The InnoDB memcached Plugin and Replication The example uses the  demo_test  table, which was created by the  innodb_memcached_config.sql configuration script during the initial setup of the  daemon_memcached  plugin. The  demo_test  table contains a single example record. 1. Use the  set  command to insert a record with a key of  test1 , a flag value of  10 , an expiration value of 0 , a cas value of 1, and a value of  t1 . 2. On the source server, check that the record was inserted into the  demo_test  table. Assuming the demo_test  table was not previously modified, there should be two records. The example record with a key of  AA , and the record you just inserted, with a key of  test1 . The  c1  column maps to the key, the c2  column to the value, the  c3  column to the flag value, the  c4  column to the cas value, and the  c5 column to the expiration time. The expiration time was set to 0, since it is unused. 3. Check to verify that the same record was replicated to the replica server. 4. Use the  set  command to update the key to a value of  new . 5. Delete the  test1  record using a  delete  command. telnet 127.0.0.1 11211 Trying 127.0.0.1... Connected to 127.0.0.1.
