Kafka: configuration by partition or by topic? -


i created topic in kafka cluster following command.

/opt/kafka/bin/kafka-topics.sh --zookeeper kaf1:2181,kaf2:2181,kaf3:2181 --create --topic mytopic --partitions 10 --replication-factor 2 --config retention.bytes=1074000000 --config delete.retention.ms=6000 --config segment.bytes=105000000

so, if understand correctly documentation, have topic 10 partitions replicate 2 times beetween 3 kafka hosts. next, each kafka host must retain 1go of data. each segment has size of 100mo , old logs delete after 1 minute.

now, when du -h on logs directory on kafka hosts, have this:

1,2g ./mytopic-2 1,1g ./mytopic-8 1,2g ./mytopic-9 1,1g ./mytopic-6 1,1g ./mytopic-3 1,1g ./mytopic-0 1,2g ./mytopic-4 7,6g .

i thought 1go directory entirely , not each partition.

so question simple, topic configuration each partition or topic ?

thanks.

please, see picture below (distribution of partitions cluster nodes might different): enter image description here

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
