what is Kryo ?

  Upvote    Share

Hi,

Kryo is a library to serialize in-memory objects fatser. It is important for Saprk to serialize objects in RAM for avoiding bottlenecks, since Saprk is in-memory. Serializing memory objects reduces the space occupied. But the serialization itself may take some time. Spark supports usage of 2 libraries for serilization: Java’s ObjectOutputStream framework(this is default) and Kyro lbrary. Kryo is significantly faster and more compact than Java serialization (often as much as 10x).

Feel free to go through https://spark.apache.org/docs/latest/tuning.html

Thanks.

Done! I have re-recorded the audio. Thank you for letting us know and being patient with us. The audio might sound a tad different than usual.
