observed in any official implementation. Furthermore, in spite of its complexity, TPC‐C is easily scaled up or down to fit the system under test. Tpcc‐mysql is Percona’s TPC‐C implementation. It is transactions per minute 2 TPC‐C database size is defined by number of warehouses (wh). All tables are scaled up or down based on the number of warehouses defined.

password of the new machine, or use the -i option to specify the private key file. If you see the Scaled cluster out successfully, the scale-out operation is successfully completed. 3. Check --node 10.0.1.5:20160 The --node parameter is the ID of the node to be taken offline. If you see the Scaled cluster in successfully, the scale-in op- eration is successfully completed. 3. Check Check the cluster status: The scale-in process takes some time. If the status of the node to be scaled in becomes Tombstone, that means the scale-in operation is successful. To check the scale-in status

Similar to steps in “Add the plugin to an existing cluster”. You need to specify the node that is scaled out (the ID shown by the tiup cluster display) with the -N parameter. Note that you need to upload

databases, ◦ numbers (DECIMAL and NUMERIC data types) are stored internally as long fixed point values (scaled integers) when the precision is greater than 9. ◦ The TIME data type is available for storing time-of-day nearest multiple of 10 • -2 for rounding to the nearest multiple of 100 Result type INTEGER, (scaled) BIGINT or DOUBLE PRECISION Description Rounds a number to the nearest integer.

integer/integer division to a float quotient, you will need to alter any affected expressions to use a float or scaled numeric type for either dividend, di- visor, or both. For example, the calculation above could be
