limit: Specifies the maximum number of records to return. There is also a size limit of 10 MB on the response that can't be modified and that takes precedence over the number of records specified in the limit
parameter. The response does include a threshold-breaching record if the 10 MB limit was reached.
The range for limit is 1 to 100,000, with a default of 10.
iteratorType: Can be one of:
AT_SEQUENCE_NUMBER – Indicates that reading should start from the event sequence number specified jointly by the commitNum and opNum parameters.
AFTER_SEQUENCE_NUMBER – Indicates that reading should start right after the event sequence number specified jointly by the commitNum and opNum parameters.
TRIM_HORIZON – Indicates that reading should start at the last untrimmed record in the system, which is the oldest unexpired (not yet deleted) record in the change-log stream.
LATEST – Indicates that reading should start at the most recent record in the system, which is the latest unexpired (not yet deleted) record in the change-log stream.
commitNum: The commit number of the starting record to read from the change-log stream. This parameter is required when iteratorType
isAT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER, and ignored when iteratorType is TRIM_HORIZON or LATEST.
opNum: The operation sequence number within the specified commit to start reading from in the change-log stream data. The default is 1.
encoding: If set to TRUE, Neptune compresses the response using gzip encoding.
