+The Kafka protocol version 3.4.0 is supported with limitations:
+
+1. Only authenticated connections allowed.
+2. Only SASL/PLAIN authentication supported.
+3. Message compression not supported.
+4. Only Manual Partition Assignment is supported in reading, [assign method](https://kafka.apache.org/35/javadoc/org/apache/kafka/clients/consumer/KafkaConsumer.html#assign(java.util.Collection)), without using consumer group partitions.
+5. Transactions not supported.
+6. DDL transactions not supported. To perform DDL operations, use the [YDB SDK](../ydb-sdk/index.md) or [YDB CLI](../ydb-cli/index.md).
+7. Data schema validation not supported.

+# Kafka API usage examples
+
+This article provides examples of usage the Kafka API to work with [topics](../../concepts/topic.md).
+
+Before executing the examples, [create a topic](../ydb-cli/topic-create.md) and [add a consumer](../ydb-cli/topic-consumer-add.md).
+
+## Examples of working with topics
+
+The examples use:
+
+ * `ydb:9093` — host name.
+ * `/Root/Database` — database name.
+ * `/Root/Database/Topic` — topic name.
+ * `user@/Root/Database` — username. Includes the username and database name.
+ * `*****` — user password.
+
+
+## Writing data to a topic
+
+### Writing via Kafka Java SDK
+
+This example includes a code snippet for writing data to a topic via Kafka Java SDK.
+
+  ```java
+  String HOST = "ydb:9093";
+  String TOPIC = "/Root/Database/Topic";
+  String USER = "user@/Root/Database";
+  String PASS = "*****";
+
+  Properties props = new Properties();
+  props.put("bootstrap.servers", HOST);
+  props.put("acks", "all");
+
+  props.put("key.serializer", StringSerializer.class.getName());
+  props.put("key.deserializer", StringDeserializer.class.getName());
+  props.put("value.serializer", StringSerializer.class.getName());
+  props.put("value.deserializer", StringDeserializer.class.getName());
+
+  props.put("security.protocol", "SASL_SSL");
+  props.put("sasl.mechanism", "PLAIN");
+  props.put("sasl.jaas.config", PlainLoginModule.class.getName() + " required username=\"" + USER + "\" password=\"" + PASS + "\";");
+
+  props.put("compression.type", "none");
+
+  Producer<String, String> producer = new KafkaProducer<>(props);
+  producer.send(new ProducerRecord<String, String>(TOPIC, "msg-key", "msg-body"));
+  producer.flush();
+  producer.close();
+  ```
+
+### Writing via Logstash
+
+To configure [Logstash](https://github.com/elastic/logstash), use the following parameters:
+
+  ```
+  output {
+    kafka {
+      codec => json
+      topic_id => "/Root/Database/Topic"
+      bootstrap_servers => "ydb:9093"
+      compression_type => none
+      security_protocol => SASL_SSL
+      sasl_mechanism => PLAIN
+      sasl_jaas_config => "org.apache.kafka.common.security.plain.PlainLoginModule required username='user@/Root/Database' password='*****';"
+    }
+  }
+  ```
+
+### Writing via Fluent Bit
+
+To configure [Fluent Bit](https://github.com/fluent/fluent-bit), use the following parameters:
+
+  ```
+  [OUTPUT]
+    name                          kafka
+    match                         *
+    Brokers                       ydb:9093
+    Topics                        /Root/Database/Topic
+    rdkafka.client.id             Fluent-bit
+    rdkafka.request.required.acks 1
+    rdkafka.log_level             7
+    rdkafka.security.protocol     SASL_SSL
+    rdkafka.sasl.mechanism        PLAIN
+    rdkafka.sasl.username         user@/Root/Database
+    rdkafka.sasl.password         *****
+  ```
+
+## Reading data from a topic
+
+### Reading data from a topic via Kafka Java SDK
+
+This example includes a code snippet for reading data from a topic via Kafka Java SDK.
+
+```java
+  String HOST = "ydb:9093";
+  String TOPIC = "/Root/Database/Topic";
+  String USER = "user@/Root/Database";
+  String PASS = "*****";
+
+  Properties props = new Properties();
+  props.put("bootstrap.servers", HOST);
+  props.put("auto.offset.reset", "earliest"); // to read from start
+  props.put("check.crcs", false);
+
+  props.put("key.deserializer", StringDeserializer.class.getName());
+  props.put("value.deserializer", StringDeserializer.class.getName());
+
+  props.put("security.protocol", "SASL_SSL");
+  props.put("sasl.mechanism", "PLAIN");
+  props.put("sasl.jaas.config", PlainLoginModule.class.getName() + " required username=\"" + USER + "\" password=\"" + PASS + "\";");
+
+  Consumer<String, String> consumer = new KafkaConsumer<>(props);
+
+  List<PartitionInfo> partitionInfos = consumer.partitionsFor(TOPIC);
+  List<TopicPartition> topicPartitions = new ArrayList<>();
+
+  for (PartitionInfo partitionInfo : partitionInfos) {
+      topicPartitions.add(new TopicPartition(partitionInfo.topic(), partitionInfo.partition()));
+  }
+  consumer.assign(topicPartitions);
+
+  while (true) {
+      ConsumerRecords<String, String> records = consumer.poll(1000);
+      for (ConsumerRecord<String, String> record : records) {
+          System.out.println(record.key() + ":" + record.value());
+      }
