* Creates an unbounded stream that continuously emits the
constant value 42L.
* Flink's DataGeneratorSource with RateLimiterStrategy is used to
control the emission rate.
*
- * Rate Calculation:
- * - samplingIntervalMs / 10 gives maxSleepTimeMs, which
represents the interval between emissions.
- * - To determine the number of records emitted per second:
- * 1000 / maxSleepTimeMs
- * Since 1000 ms equals 1 second, this formula calculates 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.
*
- * Example:
- * - If samplingIntervalMs = 1000 ms:
- * maxSleepTimeMs = 100 ms
- * - This results in:
- * 1000 ms / 100 ms = 10 records per second.
+ * 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;
*
- * RateLimiterStrategy.perSecond((double) 1000 / ((double)
samplingIntervalMs / 10))
- * ensures this rate is maintained efficiently without blocking
execution.
+ * Example Calculations:
+ * - If `samplingIntervalMs = 1000 ms`:
+ * - `samplingIntervalsPerSecond = 1000 / 1000 = 1`
+ * - `impulsesPerSecond = 10 * 1 = 10 records per second`
+ * - If `samplingIntervalMs = 500 ms`:
+ * - `samplingIntervalsPerSecond = 1000 / 500 = 2`
+ * - `impulsesPerSecond = 10 * 2 = 20 records per second`
+ * - If `samplingIntervalMs = 2000 ms`:
+ * - `samplingIntervalsPerSecond = 1000 / 2000 = 0.5`
+ * - `impulsesPerSecond = 10 * 0.5 = 5 records per second`
+ *
+ * This approach ensures that the number of records emitted
dynamically scales
Review Comment:
This sounds very AI-generated :) I the intention is clear without the last
paragraph.
Also, one example would suffice.
