Examples with Bytes org.apache.kafka.common.utils.Bytes used on opensource projects

Example 1 with Bytes

use of org.apache.kafka.common.utils.Bytes in project kafka by apache.

the class SessionKeySerde method bytesToBinary.

public static Bytes bytesToBinary(final Windowed<Bytes> sessionKey) {
    final byte[] bytes = sessionKey.key().get();
    ByteBuffer buf = ByteBuffer.allocate(bytes.length + 2 * TIMESTAMP_SIZE);
    buf.put(bytes);
    buf.putLong(sessionKey.window().end());
    buf.putLong(sessionKey.window().start());
    return new Bytes(buf.array());
}

Example 2 with Bytes

use of org.apache.kafka.common.utils.Bytes in project kafka by apache.

the class SessionKeySerde method toBinary.

public static <K> Bytes toBinary(final Windowed<K> sessionKey, final Serializer<K> serializer) {
    final byte[] bytes = serializer.serialize(SESSIONKEY, sessionKey.key());
    ByteBuffer buf = ByteBuffer.allocate(bytes.length + 2 * TIMESTAMP_SIZE);
