InsertWallclock

Inserts the system clock as a message header.

Use InsertWallclockHeaders SMT if you want to use more than one date time part. This avoids multiple SMTs and is more efficient.

For example, if you want to partition the data by yyyy-MM-dd/HH, then you can use InsertWallclockHeaders which inserts multiple headers: date, year, month, day, hour, minute, second.

Inserts the system clock as a message header, with a value of type STRING. The value can be either a string representation of the date and time epoch value, or a string representation of the date and time in the format specified for example yyyy-MM-dd HH:mm:ss.SSS.

Transform Type Class

io.lenses.connect.smt.header.InsertWallclock

Configuration

Name	Description	Type	Default	Valid Values	Importance
header.name	The name of the header to insert the timestamp into.	String			High
value.type	Sets the header value inserted. It can be epoch or string. If string is used, then the 'format' setting is required."	String	format	epoch,format	High
format	Sets the format of the header value inserted if the type was set to string. It can be any valid java date format.	String			High
timezone	Sets the timezone. It can be any valid java timezone. Overwrite it when value.type is set to format, otherwise it will raise an exception.	String	UTC		High

Example

To store the epoch value, use the following configuration:

transforms=InsertWallclock
transforms.InsertWallclock.type=io.lenses.connect.smt.header.InsertWallclock
transforms.InsertWallclock.header.name=wallclock
transforms.InsertWallclock.value.type=epoch

To store a string representation of the date and time in the format yyyy-MM-dd HH:mm:ss.SSS, use the following:

transforms=InsertWallclock
transforms.InsertWallclock.type=io.lenses.connect.smt.header.InsertWallclock
transforms.InsertWallclock.header.name=wallclock
transforms.InsertWallclock.value.type=format
transforms.InsertWallclock.format=yyyy-MM-dd HH:mm:ss.SSS

To use the timezone Asia/Kolkoata, use the following:

transforms=InsertWallclock
transforms.InsertWallclock.type=io.lenses.connect.smt.header.InsertWallclock
transforms.InsertWallclock.header.name=wallclock
transforms.InsertWallclock.value.type=format
transforms.InsertWallclock.format=yyyy-MM-dd HH:mm:ss.SSS
transforms.InsertWallclock.timezone=Asia/Kolkata
