RDD Operation Actions

in this video we are discussing our DB
0:02
operation that is actions we know that
0:05
on our DD we can carry out two different
0:07
operations one is the transformations
0:09
and the one is the actions the basic
0:12
difference between transformation and
0:13
action is that in case of transformation
0:16
it will take data from one or DD and
0:18
produces one or more than one rdd's that
0:21
means in case of transformation outcome
0:23
will be output will be one or more than
0:26
one rdd's but in case of actions it will
0:29
take data from our DD but it will
0:31
produce nan or DD as output it produces
0:34
the separate result but that is non
0:36
oddity
0:37
though these actions are our DD
0:40
operations so let us go for some more
0:42
detailing about this concept so what is
0:46
actions in our DD the spark action
0:49
returns the final result of our duty
0:52
computations so it will return the final
0:54
result but that result is in the non or
0:57
DD format and it uses lineage graph to
1:00
load data into the original or DT so
1:04
actions produces non or DD values though
1:07
it is one of the Arditi operations and
1:10
that is very important concept that this
1:12
action will produce non or DD values as
1:15
the outcome and though it is one of the
1:18
valid of operations on this our DD so
1:22
some action examples our first method
1:24
taked method counter method collect
1:28
method and so on so this is known as the
1:31
our DD operation it is known as action
1:33
