Menene mahimman abubuwan da ya kamata a yi la'akari da su yayin gudanar da Kafka a cikin aiki na gaida?

Question

Accepted Answer

Gudanar da Kafka a cikin aiki na gaida yana buƙatar mai kyau a **girman tari, maimaita, sa ido, tsaro, da kula** — Kafka tsarki mai iko amma tsarki mai hadari na rarraba. Fahimta yanayin aikin (ko amfani da Kafka na amsarwa) yana da mahimmanci don gudanar da shi daidai.

## Saita tari da amsarwa

```text
✓ Adequate BROKERS → size the cluster for throughput, storage, and replication needs
✓ REPLICATION → replication factor ≥ 3, min.insync.replicas for durability (no data loss)
✓ Spread across racks/AZs → survive failures (rack awareness)
✓ PARTITIONS → plan partition counts for parallelism and growth (hard to reduce later)
✓ Capacity planning → throughput, retention/storage, growth
```

## Sa ido da kula

```text
✓ MONITOR → consumer lag, broker health, under-replicated partitions, throughput, disk (key!)
✓ Alerting on problems (lag, under-replication, broker down, disk full)
✓ Handle DISK → retention vs storage; disk full is a serious failure
✓ UPGRADES, rebalancing partitions, scaling brokers; backup/disaster recovery
✓ KRaft (or ZooKeeper) cluster management
```

## Tsaro da zaɓuɓɓukan amsarwa

```text
✓ SECURITY → encryption (TLS), authentication (SASL), authorization (ACLs) — secure access
✓ Network isolation; don't expose Kafka openly
✓ MANAGED KAFKA → Confluent Cloud, AWS MSK, etc. → offload operational complexity
  (cluster management, scaling, patching) → often worth it to avoid the operational burden
→ Kafka is operationally complex → managed services reduce the burden significantly

## Me yake da mahimmanci

Fahimta mahimman abubuwan da ya kamata a yi la'akari da su yayin gudanar da Kafka a cikin aiki na gaida ilimin akwai mahimmanci na mataki sama domin **Kafka yana da hadari ta gida**, kuma gudanar da shi daidai yana buƙatar mai kyau a waɗannan abubuwan, saboda haka yana da mahimmanci don Kafka na aiki na gaida.

Kafka tsarki mai iko amma tsarki, kuma gudanar da shi daidai yana buƙatar fahimta ta waɗannan sassa da yawa na aiki.

Fahimta **saita tari da amsarwa** — daidaitawa da girman tari, tabbatarwa da **maimaita** (factor ≥ 3, min.insync.replicas don dorewa), baje-bajewa jiya fage/AZs (murƙuɓewa da katsintsi), plani **adadi ɓangaren** (don jajafawa da tasowa, saboda ba zai iya raguwa ba sauri), kuma plani ƙarfi — yana nuna saita Kafka don amsarwa da miski.

Fahimta **sa ido da kula** — sa ido da ciwon ɗi mai amfani, lafiyar brokoji, **ɓangare da bai cika ba**, abin da ake yanke, kuma musamman **diski** (domin cikakken diski babbar gazawa ta karshe), ƙarancin abubuwan da ba daidai ba, sha'awa kan matsaloli, shakatawa da ajiya, madaidaitan sassa, da canji na katsintsi, kuma samar da canji — yana nuna ci gaba na aiki na gudanar da Kafka.

Fahimta **tsaro** — shakatawa (TLS), shaida (SASL), izini (ACLs), kuma ware na cibiyar sadarwa — yana da mahimmanci don tsaron Kafka.

Waje, fahimta **zaɓuɓɗun Kafka na amsarwa** (Confluent Cloud, AWS MSK) wanda **baje baje a hadarin aiki** (gudanar da tari, miski, shakatawa) ƙarancin aiki ne mai girma, domin kulo Kafka na aiki yana da nauyi kuma wurare na amsarwa yawanci daceyi ne.

Mahimmin fahimta ita ce cewa Kafka yana da hadari ta gida, saboda gudanar da shi daidai yana buƙatar aiki na gida na gaske (ko amfani da serbis na amsarwa don baje-baje shi).

Wannan fahimta ta aiki yana nuna girma don gudanar da Kafka da hankali a aikin gaida.

Domin Kafka yana da hadari ta gida kuma gudanar da shi daidai yana buƙatar mai kyau ga girman tari, maimaita, sa ido (musamman ciwon ɓi da diski), tsaro, kula, kuma zaɓon serbis na amsarwa, kuma domin fahimta yanayin aikin wannan yana da mahimmanci don Kafka na aiki na gaida, fahimta mahimman abubuwan da ya kamata a yi la'akari da su yayin gudanar da Kafka a cikin aiki na gaida ilimin akwai mahimmanci na mataki sama — mahimmanci don gudanar da Kafka daidai ta karshe domin hadarin aikin sa, yana rufe amsarwa ta tari, sa ido, tsaro, kuma zaɓon serbis na amsarwa, kuma yana nuna girman aiki da aka taba da sa jiya daga jami'an mataki sama da ke karbar karbar Kafka na aiki na gaida.
