You can first departition your 8 ways multifile and make it serial then in next step partition it using any partition component and transfer it to host/directory which is 10 ways partitioned.

I have a question here..Why is not possible to use another partition component to convert to depth 10 ...why do we need to serialize it first?

Thanks in advance.

Cant it be done without serializing it by using another partition component?

Thanks

First use a 'gather' and then 'partition by round robin'....

You can re-partition only if the depth is n times existing depth

This is not true.

We can repartition even if the new depth is not n times the existing depth.

For repartitioning an 8way file to a 10 way file u just have to use another partition component (depending on the way u want to partition u can use partition by key, expression, round_robin etc). The flow should be all - to all and the output file should reside in a 10 way partitioned multifile directory.

No need to serialize the data first.

Thats correct. We need not serialize the data for changing the depth.
I have used one way for this .

Use any partition component > Go to Layout tab > Custom >Edit and give the absolute paths over there as per your required depth.

It works this way too.

We can simply use any partition component (partition by key, round robin or anything) to achieve this. Just Specify the target multi file system location in the layout of the partition component. There you go!!

We can use re-partition component just like partition by key & sort. In that layout we can change the depth.
