> Hello!
> h2. TC to reproduce:
> 1) Create GenerateFlowFile with the next Custom Text:
> {code:sql}
> select 1 from dual
> union all
> select 2 from dual
> union all
> select 3 from dual
> {code}
> 2) Create ExecuteSQL. Set "Output Batch Size" = 1.
> 3) Start
> h2. AR:
>  !image-2019-02-15-18-13-39-190.png!
> h2. ER:
> 3 flowfiles in the "success" connection.
> h2. Root Cause:
> {code:java}
> if (outputBatchSize > 0 && resultSetFlowFiles.size() >= outputBatchSize) {
>     session.transfer(resultSetFlowFiles, REL_SUCCESS);
>     session.commit();
>     resultSetFlowFiles.clear();
> }
> {code}
> Commit method has the next requirement:
> Commits the current session ensuring all operations against FlowFiles within this session are atomically persisted. *All FlowFiles operated on within this session must be accounted for by transfer or removal or the commit will fail*.
> At the time of any commit, an input flowfile (fileToProcess) still exists and has not been accounted for by transfer or removal.
