HI All, Please give me some inputs on *Partition Column *to be used in DataSourceAPI or JDBCRDD to define Lowerbound and Upperbound value which would be used to define No. of partitions, but issue is my source table does not have a Numeric Columns which is sequential and unique such that proper partitioning can take place
And what if we dont give any inputs as such for Lowerbound,Upperbound and No. of partitions, how Spark can perform execution in distributed mode/parallel and is there any default mode to perform in distributed mode/parallel with out the above mentioned inputs Regards, Satish Chandra Jummula ---------- Forwarded message ---------- From: satish chandra j <jsatishchan...@gmail.com> Date: Wed, Sep 30, 2015 at 2:10 PM Subject: Partition Column in JDBCRDD or Datasource API To: user <user@spark.apache.org> HI All, Please provide your inputs on Partition Column to be used in DataSourceAPI or JDBCRDD in a scenerio where the source table does not have a Numeric Columns which is sequential and unique such that proper partitioning can take place in Spark Regards, Satish
