Is éard atá i ailtireacht Kafka ná cluster de bhróicéirí (freastalaithe) ag stóráil topicí deighilte, atáirgeadaithe, le táirgeoirí ag scríobh agus tomhaltóirí ag léamh, arna gcomhordú ag bainistíochta meiteashonraí (go stairiúil ZooKeeper, anois KRaft). Soiléiríonn tuiscint ar an ailtireacht conas a oibríonn Kafka mar chóras dáilte.
Na comhpháirteanna
BROKERS → Kafka SERVERS forming a CLUSTER:
→ store topic partitions (the data); serve producers and consumers
→ a cluster of multiple brokers → distributes data and load; scales horizontally
TOPICS / PARTITIONS → topics split into partitions, distributed across brokers
PRODUCERS → write events to topics (to partition leaders)
CONSUMERS (in groups) → read events from partitions
COORDINATION → metadata, cluster state, leader election:
→ historically ZOOKEEPER; now KRAFT (Kafka's own built-in consensus, removing ZooKeeper)
