## Abin da jarin sarrafa shine

```text
STREAM PROCESSING → process data CONTINUOUSLY as it arrives (in real time), vs batch
(processing stored data periodically):
  → consume events from topics, transform/analyze them, produce results (often to other topics)
  → real-time: react to and process events as they happen (low latency)
→ for: real-time analytics, transformations, monitoring, enrichment, aggregations
```

## Abin da Kafka Streams ya ba

```text
KAFKA STREAMS = a Java/Scala LIBRARY for building stream-processing apps on Kafka:
  → read from topics, process, write to topics (a processing topology)
  → OPERATIONS: map, filter, transform; aggregations (count, sum); windowing (time windows);
    JOINS (join streams/tables)
  → STATEFUL processing → maintain state (e.g. running counts) with fault tolerance
  → STREAMS vs TABLES → a stream (events) and a table (state/changelog) duality (KStream/KTable)
  → it's a library (runs in your app) — no separate cluster needed (vs Flink/Spark)
```

## Amfani da madala

```text
USES → real-time analytics, data transformation/enrichment, aggregations, monitoring,
  event-driven processing, materialized views
ALTERNATIVES → Apache FLINK, Spark Streaming (more powerful, separate clusters);
  ksqlDB (SQL on Kafka streams)
→ Kafka Streams: simple (a library), good for Kafka-centric processing
```
