) How can you count the total no .of records in the
specified partition in the Multifile?
Answer Posted / prakashbalakrishnan
In Multi Files, data's are stored in individual partitions.
i.e. for 3 way partition, it will stored as
/wload/xxx/xxx/1way/../test.dat,
/wload/xxx/xxx/2way/../test.dat,/wload/xxx/xxx/3way/../test.dat
SO in unix u can easily the find the different partitions
and for the corresponding partition u can get toal no. of
records by using wc command.
