Circuit Breaker Pattern என்பது என்ன?
Circuit Breaker pattern என்பது ஒரு மென்பொருள் வடிவமைப்பு முறைமையாகும். இது குறிப்பாக cloud-based microservices, distributed systems மற்றும் IT infra-யில் application-களுக்கு error tolerance/நிலைத்தன்மை அளிக்க வேண்டும். இந்த pattern, எந்த service அல்லது resource இடையே repeated failure வந்தாலும், application அந்தச் service-யை தொடர்ந்து request செய்யும் போது resources தேங்கிச் செலவாகும், performance குறையாமல் இருக்க design செய்யப்பட்டு இருக்கிறது. Real-world electric circuit breaker போல் threshold values பாதுகாப்பு செய்யும்; ஒரு limit கடந்து failure வரும்போது, circuit break செய்து (requests stop), system-க்கு மீண்டும் நிலைமாட்டும் வாய்ப்பு தரும்.
இதன் நோக்கம், cascading failure-ஐத் தவிர்த்து, system விரைவில் normal-க்கு வந்து விடச் செய்யும். நேரடியாகத் தொடர்ந்த failures-க்கு alternate route, fallback logic அல்லது user-friendly error message தரும். மற்ற components unaffected-ஆ irukkum; site/user experience-க்கு பாதிப்பு குறையும்; overall reliability, availability maximize செய்யும்.
Circuit Breaker Pattern-இன் முக்கிய structs
- Closed: Service-க்கு normal request கள் செல்லும். Error-rate (failure-rate) முன் limit-ஐ கடந்து விட்டால் circuit open-ஆகும்.
- Open: Service-க்கு requests தடுமாறாமல் reject செய்யப்படும். Retry period முடிந்ததும் half-open-க்கு வரும்.
- Half-Open: Few requests permitted. Success ஆகும் என்றால் sealed/closed-காக மீண்டும் செல்லும். Failure வந்தால் open continued.
- Failure Threshold: Circuit open-ஆக trigger செய்ய தேவையான failure-க்கள் limit.
- Retry Timeout: Open state-ல் இருந்து Half-Open-க்கு மறுசீரமைப்புக்கு ஒரு waiting time.
Circuit Breaker pattern, distributed-களில் resilience-யும் flexibility-யும் கூடுதலாக தருகிறது. Microservices-ல், interservice dependency complexity-க்கு இந்த pattern-இன் பலன் அதிகம். Error tolerance implementation-க்கு, Circuit Breaker不可欠. அடுத்து, மைக்ரோசெர்விஸ் معماریயில் errors-ஐ handle செய்வது எப்படி, Circuit Breaker வெளியில்இன்ற phase-ஐப் பார்ப்போம்.
Circuit Breaker state transition details:
| நிலை | விளக்கம் | அறுவைக்கும் செயல் |
|---|---|---|
| Closed | Normal service calls. | Success calls stay closed. Failure rate exceeds threshold, moves to Open. |
| Open | Service calls blocked. | Calls fail immediately. Timer triggers Half-Open. |
| Half-Open | Few service calls allowed. | Success: Back to Closed. Failure: Stays Open. |
| Wait | Inter-state wait. | Duration ends, status transitions. |
Circuit Breaker pattern, distributed infra-வின் fault tolerance, reliability-க்கு Tamil web hosting-ற்கு நம்பிக்கையா உதவுகிறது. சரியாக அமலாக்கும் போது, User experience-யும் resource utilization-யும் வளமாகும். Microservice, cloud-இல் must-have design-element-ஆக circuit breaker-ன் அர்த்தம் பெருமளவு.

Complexity remains, though: Distributed-system management, monitoring, security, must focus.
பிழை சகிப்புத் தன்மை முக்கியத்துவம்
Microservice infra-யில் interservice continuous communication, one error — whole app or segments affected. Error tolerance needed: One/few component failure, rest of system unaffected. Error tolerance ensures minimal downtime, business continuity, SLA promise.
Error tolerance not just tech, but team advantage. When a service fails, error-handling techniques auto isolates/recovers, reduces urgent interventions; gives teams time to analyze root cause.
Microservice infra fault tolerance pros-table:
| Criteria | Without Tolerance | With Tolerance |
|---|---|---|

Strategic review— performance tests, update tolerance logic, avoid risks.
Circuit Breaker மாதிரியின் செயல்முறை
Circuit Breaker model prevents error propagation and resource exhaustion. If service calls repeatedly fail past threshold, subsequent calls auto marked failed: Gives repair-time, protects others.
Three states: Closed, Open, Half-Open. Starts closed; failures pass threshold opens circuit; further calls fail fast. Prevents resource waste.
Circuit Breaker operation steps:
- Closed State: All calls pass, success monitored.
- Open State: Circuit opens when failures high; calls fail instantly.
- Half-Open State: After wait, small number tested; if success, circuit closes, else stays open.
- Success Check: Half-open successes—close circuit.
- Failure Handling: Half-open failures—stay open.
| State | Description | Action |
|---|---|---|
| Closed | Service healthy | Calls pass to service |
| Open | Service failed/overloaded | Calls fail immediately |
| Half-Open | Testing if service recovered | Limited calls allowed |
| Recovery | Service healthy again | Back to closed |
Half-open key: Periodic small requests check recovery. If successful, circuit closes—normal. If failed, remains open; recovery retests. This cycle maintains system health, early recovery.
Microservice infra; Circuit Breaker key tool. Prevents chain failure, keeps system robust.
