What breaks: three orchestration failures
Lesson 68 of 175 · 2 min
Three orchestration failures, and all three are about what happens when something goes wrong halfway. ONE: A LOOP THAT STOPPED AT THE FIRST BAD RECORD. Five hundred records, one malformed at position three, and 497 good ones never processed. The run reports a failure, correctly — and the business impact is out of all proportion to the cause. Continue-on-error with a collected failure list is the pattern, and this failure is what it exists to prevent. Lesson 4. TWO: A SYNCHRONOUS CALL THAT TIMED OUT AFTER SUCCEEDING. The caller gave up; the work completed. Two systems now disagree about whether something happened, and a retry produces a duplicate. Nothing is broken in either system, which is what makes it hard to diagnose and impossible to prevent after the fact. Lesson 7, and idempotency is the answer. THREE: A SUB-INTEGRATION UPDATED UNDER ITS CALLERS. Changed and reactivated, tested against one caller,…
