Trigger a flow on real-time message consumption from a DB2 database via change data capture and create one execution per row.
If you would like to consume multiple messages processed within a given time frame and process them in batch, you can use the io.kestra.plugin.debezium.db2.Trigger instead.

YESADD_FIELDADD_FIELDDROPSpecify how to handle key.
Possible settings are:
ADD_FIELD: Add key(s) merged with columns.DROP: Drop keys.
YESADD_FIELDADD_FIELDDROPSpecify how to handle metadata.
Possible settings are:

YESON_STOPON_EACH_BATCHON_STOPWhen to commit the offsets to the KV Store.
ON_EACH_BATCH: after each batch of records consumed by this trigger, the offsets will be stored in the KV Store. This avoids any duplicated records being consumed but can be costly if many events are produced.ON_STOP: when this trigger is stopped or killed, the offsets will be stored in the KV Store. This avoids any un-necessary writes to the KV Store, but if the trigger is not stopped gracefully, the KV Store value may not be updated leading to duplicated records consumption.
YESPassword on the remote server.
YESAdditional configuration properties.

YESINITIALALWAYSINITIALINITIAL_ONLYWHEN_NEEDEDNO_DATARECOVERYSpecifies the criteria for running a snapshot when the connector starts.
Possible settings are:
ALWAYS: The connector performs a snapshot every time that it starts.INITIAL: The connector runs a snapshot only when no offsets have been recorded for the logical server name.INITIAL_ONLY: The connector runs a snapshot only when no offsets have been recorded for the logical server name and then stops; i.e. it will not read change events from the binlog.WHEN_NEEDED: After the connector starts, it performs a snapshot only if it detects one of the following circumstances: 1. It cannot detect any topic offsets. 2. A previously recorded offset specifies a log position that is not available on the server.NO_DATA: The connector captures the structure of all relevant tables, performing all the steps described in the INITIAL, except that it does not create READ events to represent the data set at the point of the connector’s start-up.RECOVERY: Set this option to restore a database schema history topic that is lost or corrupted. After a restart, the connector runs a snapshot that rebuilds the topic from the source tables.
YESTABLEOFFDATABASETABLESplit table on separate output uris.
Possible settings are:
TABLE: This will split all rows by tables on output with namedatabase.tableDATABASE: This will split all rows by databases on output with namedatabase.OFF: This will NOT split all rows resulting in a singledataoutput.

NOpartial-timeSLA daily deadline
Use it only for DAILY_TIME_DEADLINE SLA.
NOpartial-timeSLA daily end time
Use it only for DAILY_TIME_WINDOW SLA.
NOpartial-timeSLA daily start time
Use it only for DAILY_TIME_WINDOW SLA.
NODURATION_WINDOWDAILY_TIME_DEADLINEDAILY_TIME_WINDOWDURATION_WINDOWSLIDING_WINDOWThe type of the SLA
The default SLA is a sliding window (DURATION_WINDOW) with a window of 24 hours.
NOdurationThe duration of the window
Use it only for DURATION_WINDOW or SLIDING_WINDOW SLA.
See ISO_8601 Durations for more information of available duration value.
The start of the window is always based on midnight except if you set windowAdvance parameter. Eg if you have a 10 minutes (PT10M) window,
the first window will be 00: 00 to 00: 10 and a new window will be started each 10 minutes
NOdurationThe window advance duration
Use it only for DURATION_WINDOW SLA.
Allow to specify the start time of the window
Eg: you want a window of 6 hours (window=PT6H), by default the check will be done between: 00: 00 and 06: 00, 06: 00 and 12: 00, 12: 00 and 18: 00, and 18: 00 and 00: 00.
If you want to check the window between 03: 00 and 09: 00, 09: 00 and 15: 00, 15: 00 and 21: 00, and 21: 00 and 3: 00, you will have to shift the window of 3 hours by settings windowAdvance: PT3H

NOfalseWhether to look at the flow namespace by prefix. Shortcut for comparison: PREFIX.
Only used when comparison is not set
NO^[a-zA-Z0-9][a-zA-Z0-9_-]*1A unique id for the condition
NONOtrueWhether to reset the evaluation results of SLA conditions after a first successful evaluation within the given time period.
By default, after a successful evaluation of the set of SLA conditions, the evaluation result is reset, so, the same set of conditions needs to be successfully evaluated again in the same time period to trigger a new execution.
This means that to create multiple executions, the same set of conditions needs to be evaluated to true multiple times.
You can disable this by setting this property to false so that, within the same period, each time one of the conditions is satisfied again after a successful evaluation, it will trigger a new execution.
NO{
"type": "DURATION_WINDOW"
}Define the time period (or window) for evaluating preconditions.
You can set the type of sla to one of the following values:
DURATION_WINDOW: this is the defaulttype. It uses a start time (windowAdvance) and end time (window) that are moving forward to the next interval whenever the evaluation time reaches the end time, based on the defined durationwindow. For example, with a 1-day window (the default option:window: PT1D), the SLA conditions are always evaluated during 24h starting at midnight (i.e. at time 00: 00: 00) each day. If you setwindowAdvance: PT6H, the window will start at 6 AM each day. If you setwindowAdvance: PT6Hand you also override thewindowproperty toPT6H, the window will start at 6 AM and last for 6 hours — as a result, Kestra will check the SLA conditions during the following time periods: 06: 00 to 12: 00, 12: 00 to 18: 00, 18: 00 to 00: 00, and 00: 00 to 06: 00, and so on.SLIDING_WINDOW: this option also evaluates SLA conditions over a fixed timewindow, but it always goes backward from the current time. For example, a sliding window of 1 hour (window: PT1H) will evaluate executions for the past hour (so between now and one hour before now). It uses a default window of 1 day.DAILY_TIME_DEADLINE: this option declares that some SLA conditions should be met "before a specific time in a day". With the string propertydeadline, you can configure a daily cutoff for checking conditions. For example,deadline: "09: 00: 00"means that the defined SLA conditions should be met from midnight until 9 AM each day; otherwise, the flow will not be triggered.DAILY_TIME_WINDOW: this option declares that some SLA conditions should be met "within a given time range in a day". For example, a window fromstartTime: "06: 00: 00"toendTime: "09: 00: 00"evaluates executions within that interval each day. This option is particularly useful for declarative definition of freshness conditions when building data pipelines. For example, if you only need one successful execution within a given time range to guarantee that some data has been successfully refreshed in order for you to proceed with the next steps of your pipeline, this option can be more useful than a strict DAG-based approach. Usually, each failure in your flow would block the entire pipeline, whereas with this option, you can proceed with the next steps of the pipeline as soon as the data is successfully refreshed at least once within the given time range.
