Generate

The Generate input produces synthetic text messages at a fixed interval, primarily for testing, demos, and benchmarking. Each read returns batch_size copies of the same context string.

Configuration

Field	Type	Required	Default	Description
type	string	yes	—	Constant value "generate"
context	string	yes	—	Payload text for each message
interval	duration	yes	—	Interval between reads, e.g. 1ms, 1s, 1m (the first read is immediate)
count	integer	no	—	Total number of messages; returns EOF once reached. Unset means unlimited
batch_size	integer	no	1	Number of messages returned per read
