You can dynamically change the name : put a context variable in "file name" field.
You can also use "export as context" in the Metadata repository.
>You can change the file name in the job.
i have to do it, dinamically. I will not runn all jobs by hands. Is there a way to change job properties at runtime?
Anyway: i have to reuse schema definition a lot in different components. i do not want to edit manually each time, i would like to define it once. Is it possible?
1) You can change the file name in the job. (File Name in Component properties).
2) I guess creating a metadata file takes a long time because talend read the file to determine field type (String, Integer etc...)
I have some Excel files to migrate, which have same structure (i.e column name, column order)
In TOS i would like to create a metadata for that schema, but without linking it to a specific file: the file will change, but the schema will be the same.
What i have to do so far is to create a new Metadata-> File Excel, but in this case i can only use that schema on that file.
i have two questions:
1) Is it possible to define generic schemas for excel files?
2) Creating a metadata file takes a long time before ending (7/ 10 minutes). The Excel file is about 15Mb.
Why does it takes so much time? i only need it to load the schema of the file. It is not necessary that it reads all the file.
Maybe i do not know the meaning of Metadata for files: does it keep in RAM all the file to be quicker when running job?
