Hi Aru ji, How frequently data is stored in disc?. Though it may be a streaming data, lots n lots of data are transacting for a period of time. so How can we provide reliability in capturing a data from servers(like twitter,FB, Fouresquare),

[@Tamilboomi]

Hi Kiruba,
1) We can specify when the data needs to be stored in to the disc Or if our memory (RAM) size is less than the amount of data to be processed it automatically stores the data in to disc.So Its our call.
2) For reliability on streaming data we can store it in any underlying storage like HDFS.
