+ * Creates an unbounded stream that continuously emits the
constant value 42L.
+ * Flink's DataGeneratorSource with RateLimiterStrategy is used to
control the emission rate.
+ *
+ * Emission Rate Logic:
+ * - The goal is to generate a fixed number of impulses per
sampling interval.
+ * - `samplingIntervalMs` defines the duration of one sampling
interval in milliseconds.
+ * - We define `IMPULSES_PER_SAMPLING_INTERVAL = 10`, meaning that
for every sampling interval,
+ * exactly 10 impulses should be generated.
+ *
+ * To calculate the total number of records emitted per second:
+ * 1. Determine how many sampling intervals fit within one second:
+ * samplingIntervalsPerSecond = 1000 / samplingIntervalMs;
+ * 2. Multiply this by the number of impulses per interval to get
the total rate:
+ * impulsesPerSecond = IMPULSES_PER_SAMPLING_INTERVAL *
samplingIntervalsPerSecond;
+ *
+ * Example:
+ * - If `samplingIntervalMs = 500 ms` and
`IMPULSES_PER_SAMPLING_INTERVAL = 10`:
Review Comment:
nit: either introduce this constant and use it in the calculations or use
plain text in the comment.
