performance issue on a tAggregate
Hello
i ve got big problem of performance with a tAggregateRow
40 000 rows arrive on the tAggregateRow ,
for the rest of the component the performance are ok, but for this one it's very long
is there a solution to solve the problem (we are using 2.4.0)
Here is a sysout of the start and end hashes for each component
the component tAggregateRow has the following setting
- group by 2 fields
- sum on 15 fields
- min on 15 fields
thanks in advance

Re: performance issue on a tAggregate
You can now install it from http://www.talendforge.org/ext/index.php or from TOS Ecosystem view.
Warning, because of a current limitation of the Ecosystem you have to install the three following packages which represents one component :
- tAggregateRowOpt
- tAggregateRowOptIn
- tAggregateRowOptOut
I tested it on 2.4.0 but unfortunately it does not work on this version for any reason ... Yet it works on 2.3.3 (with a minor modification) and 2.4.1, 2.4.2, 2.4.3, 3.0.0 and 3.0.1.
Maybe you will be more lucky.
