The Quartz connector in Mule allows scheduling of events using cron expressions or repeat intervals. Cron expressions provide powerful scheduling capabilities like executing jobs weekly or monthly on a specific date. Attributes of the Quartz connector include display name, cron expression, repeat interval, repeat count, start delay, and job. Jobs perform actions when triggers occur, and connector configurations associate endpoints with global configurations.

Quartz Connector - Mule

2. Description :
 The Quartz Connector supports the scheduling of
programmatic events, both inside and outside
your Mule flow. An inbound quartz endpoint can
be used to trigger inbound events that can be
repeated, such as every second. Outbound
quartz endpoints can be used to schedule an
existing event to fire at a later date. Users can
create schedules using cron expressions, and
events can be persisted in a database.

3. Attributes :
 The attributes under general properties available
while configuring Quartz connector are :
 Display Name
 Cron Expression
 Repeat Interval
 Repeat count
 Start delay
 Job :
 Connector Configuration

4.  a. Display Name : It can be anything.
 b. Cron Expression : A cron expression is a
string comprised by six or seven fields in it
separated by white space. Fields can contain any
of the allowed values, along with the various
combinations of allowed special characters for
that field.

5.  We can use cron expressions to create
schedulers.
 Cron expression can be as simple as : * * * * ? *.
 More complex expression is : 0 0/5 14,18,3-39,52
? JAN,MAR,SEP MON-FRI 2002-2010.
 The CronTrigger uses the powerful "cron
expressions" that helps to set more powerful
schedules like "Executing a job every Thursday
morning at 6.00 AM" or "Executing a job at 45
minutes past midnight on a daily basis" etc.

6. Format for cron expression:

7.  c. Repeat Interval :
 This acts as a default scheduler. If no cron
expression is given, then this helps in providing
the required time schedule. But this is not as
powerful as cron. It has only three fields : Hours,
minutes and seconds. We cannot use this repeat
interval to schedule for a day in a week or month
or year.

8.  d. Repeat count :
 Represented in milli seconds.
 If the Repeat Count is 0, then the instruction will
be interpreted as FireNow.
 If the Repeat Count is > 0, then the instruction will
be interpreted as
RescheduleNowWithExistingRepeatCount.
 If the Repeat Count is -1, then the instruction will
be interpreted as FireNowAndRepeatForever.

9.  e. Start delay :
 Represented in milli seconds.
 It is the delay before starting the job for the first
time.
 f. Job :
 Jobs are used to perform an action when a time
trigger occurs from the Quartz component. Mule
provides number of jobs for generating and
scheduling events.

10.  g. Connector Configuration :
 Use the dropdown list to select a previously
configured connector configuration for this
endpoint. If you have not created a connector
configuration for this type of endpoint, you can do
so from this window by clicking Add. Click Edit to
modify a previously created global element.
