How to upload the range of files into database in talend - talend

Question

Currently I have 14 files in my directory, I want to upload them into 7 per batch means want to upload 7 files first and then remaining 7 files.
Can you please tell me the flow.

Answer 1

Job design should be like this .
1- in tJava_1 i have done dummy logs :
System.out.println(((String)globalMap.get("tFileList_1_CURRENT_FILEPATH")));
2- tfileproperties (i will need the mtime variable to get when the file was created) has a configuration as file :
((String)globalMap.get("tFileList_1_CURRENT_FILEPATH"))
3- tBufferOutput component will store you the data
4- tBufferInput component to get the data stored in tBufferOutput (don't forget to get the schema )
5- tSortRow component to sort by mtime
6- tJava_2
System.out.println(((Integer)globalMap.get("tBufferInput_1_NB_LINE")));
// to get 7 first files
int j=((Integer)globalMap.get("tBufferInput_1_NB_LINE"))-7 ;
globalMap.put("j",j) ;
7- tloop would have While configuration :
Declare int i=0
Condition : i<(int)globalMap.get("j")
itération : i++

Other way is to do it like this :
we can do with combination of tFileList and tFileExist components.
1- Let us Assume A1 is the Source.
2-Create A2 and A3 two other folders.
3- Iterate A1 folders with tFileList and use tFileExists -A2 directory path and global variable "tFileList_1_CURRENT_FILE to check the files in A2.
4- After TfileExistsuse condition tFileExist_2_EXISTS then copy the file using tFileCopy to Folder A3.
5- At end of run make sync between A1 and A2.
6- After processing new files in A3 archive/delete them
7- Like this every run new files will be stored in A3.
