This flow shows the rate of SQL compilations and re-compilations.
All SQL statements need to be compiled by SQL Azure before they are run. Compiling is the process by which SQL Azure converts the SQL statement into an executable query plan.
Under certain circumstances, SQL Azure will re-compile SQL statements. Recompiling can consume a large amount of CPU and can degrade performance.
Good coding practices such as using Stored Procedures and parameterizing queries can help to reduce recompiles.
