Calculate the proxy database size If using order-preserving encryption, determine the size of your MySQL database by multiplying the number of potential records by record size. About this task Note: Use a dedicated machine to run the proxy database. Do not run the database on the same hardware as the proxy server. Procedure Determine the potential number of records that could include fields encrypted with order-preserving encryption. Multiply the number of encryption configurations using order-preserving encryption by the number of records each configuration is applied to. To allow for growth, multiply the result by three. Multiply the result of step 1 by 1,536. 1,536 is the average size of a record in bytes. ResultThe calculated value is the recommended size in bytes for your proxy database.
