How to design job so that it starts from the failure point?

[Pri_passion]

i have a situation :

when processing 10 rows from source to target. If the job fails at 8th record. How to design or which components to use so that the job starts from the 8th record?

can we use tmemorizeRow component ,if yes then how?

I think the only way to do this, is to save a failed row pointer somewhere outside the job (in a file ? ), and use it in next execution in input condition. tMemorizeRow works only in one time job execution. If it fails you loose your memorized row.

Hi,

on Talend Exchange, there is an excellent set of components that are exactly for this.

tCheckpointStart

tCheckpoint

tCheckpointEnd

I’ve used them exstensively and they work perfectly.

Thanks
