Test task from Xena Exchange


Write single-thread de-duplicating handler for job(id, timestamp). Jobs ordered by timestamp. Deduplication by job.id in statically configured time window.

Test setup

Benchmark test suite should generate identical load for each tested handler. Configurable deduplication window size, jobs rate borders and duplicate probability. Handler results correctness checks. Handlers resource consumption check. Randomization seed may be passed as RAND_SEED env variable.

Run bench

go test -bench=. -cpu=1 -benchtime=10000x -benchmem

Test uses manual GC invocation after each job processing for most accurate heap usage analyse, so tests make take a while – be patient or decrease benchtime…
