GitHub user lionants02 closed a discussion: I want to write/read multiple files simultaneously with Specify copies
I want to write/read multiple files simultaneously with Specify copies feature. Someone suggested me to try Hop to migrate from my old PDI system, but I have problems with "Serialize To File" for multiple writes and "De-Serialized From File". I have hundreds of millions of rows processed almost every 3-4 hours. One of the bottlenecks is file read/write. In PDI, I increased the speed by adding Specify copies for write and read, but in Apache, I can't find any documentation about the reference to ${Internal.Step.CopyNr} that can be used instead. Can anyone advise me? If I have to do it manually by copying and pasting multiple file writers with about 30-40 files without any parameters, it will be quite difficult for me.
