Connector Message Processing Properties
Overview
Use the settings on this page to configure the message processing behavior of the MongoDB Kafka sink connector including the following:
Message batch size
Rate limits
Number of parallel tasks
For a list of sink connector configuration settings organized by category, see the guide on Sink Connector Configuration Properties.
Settings
Name | Description | ||
|---|---|---|---|
max.batch.size | Type: int Description: Maximum number of sink records to batch together for processing. Consider the batch that contains the following records: When set to 0, the connector performs a single bulk write for
the entire batch.When set to 1, the connector performs one bulk write for each
record in the batch, for a total of five bulk writes as shown in
the following example:Default: 0Accepted Values: An integer | ||
bulk.write.ordered | Type: boolean Description: Whether the connector writes a batch of records
as an ordered or unordered bulk write operation.
When set to true, the default value, the
connector writes a batch of records as an ordered bulk write
operation.To learn more about bulk write operations, see
Bulk Write Operations. Default: trueAccepted Values: true or false | ||
rate.limiting.every.n | Type: int Description: Number of batches of records the sink connector processes in
order to trigger the rate limiting timeout. A value of 0 means no
rate limiting. Default: 0Accepted Values: An integer | ||
rate.limiting.timeout | Type: int Description: How long (in milliseconds) to wait before the sink connector
should resume processing after reaching the rate limiting
threshold. Default: 0Accepted Values: An integer | ||
tasks.max | Type: int Description: The maximum number of tasks to create for this connector. The
connector may create fewer than the maximum tasks specified if it
cannot handle the level of parallelism you specify. IMPORTANT: If you specify a value greater than 1,
the connector enables parallel processing of the tasks.
If your topic has multiple partition logs, which enables
the connector to read from the topic in parallel,
the tasks may process the messages out of order.Default: 1Accepted Values: An integer |
