How to get rid of file overwrite problem in Talend

Many times we see we lost the file's content while writing data into file multiple times. e.g. there is a excel file in which we are writing any data multiple time in some cases it only contains last date we have written, even after we used append option properly. So what is the solution.

here is a work a round solution.



rather writing directly on file you can first write in buffer output you all data and when all data will write use onSubjobOk trigger and use buffer input component in order to write your data in excel file.

this technique helped me a lot, hope you can also use this in your jobs :)
