# Calculate the order-preserving and tokenization database size

# Calculate the order-preserving and tokenization database size {#ariaid-title1}

If using order-preserving encryption or encryption patterns, determine the size of
your MySQL database by multiplying the number of potential records by record
size.

## Before you begin

Role required: admin

## About this task

Use a dedicated machine to run the order-preserving and tokenization database. Do not
run the database on the same hardware as the proxy server.

## Procedure

1. Determine the potential number of records that could include fields encrypted with order-preserving encryption.
   1. Multiply the number of encryption configurations using order-preserving encryption by the number of records each configuration is applied to.
   2. To allow for growth, multiply the result by three.

2. Multiply the result of step 1 by 1,536.  
   1,536 is the average size of a record in bytes.
3. If using encryption patterns, perform steps 1--2 for tokenized records and add the result to the total.

## Result

The calculated value is the recommended size in bytes for your order-preserving and
tokenization database.
