mysql - Throttling Mule Messages in Mule -

-

i've polling process in mule queries mysql database every 30 seconds , sends email recipient. how limit sending 1 email regardless of polling cycle whether 30 seconds or 15 seconds? i'm open counter in mysql db if that's option.

thank you.

write condition send email if emailsentflag == false.

use choice router create condition, , objectstore hold emailsentflag value. 

<flow...>         ....         <objectstore:retrieve config-ref="objectstore__configuration" key="emailsentflag" defaultvalue-ref="#[false]" targetproperty="flowvars.emailsentflag" doc:name="retrieve emailsentflag"/>         <choice doc:name="isemailsent?">             <when expression="#[flowvars.emailsentflag == true]">                 <logger level="info" doc:name="log email sent"/>             </when>             <otherwise>                 <smtp:outbound-endpoint host="" user="" password="" to="" from="" subject="test" cc="" bcc="" replyto="" responsetimeout="10000" ref="gmail" doc:name="smtp" connector-ref="gmail"/>                 <objectstore:store config-ref="objectstore__configuration" key="emailsentflag" value-ref="#[true]" doc:name="store emailsentflag"/>             </otherwise>         </choice>     </flow>

also explore ttl , persistence feature of objectstore, useful you.

cheers
