Re: java.lang.OutOfMemoryError: Java heap space : NIFI 1.23.2

2024-03-19 Thread e-sociaux

Hello Joe,

 

Thanks for the response.

But I found the solution. 

 

Like the table size is around 7,6GB (avro) for 161000 rows 

And I setup Fetch size : 20 so the processor ExecuteSQL try to fetch all datas.

 

Like the heap size is setup to 8GB

I have reduced the "Fetch Size" to 1 and it is worked.

 

Regards

Re: java.lang.OutOfMemoryError: Java heap space : NIFI 1.23.2

2024-03-19 Thread Matt Burgess

Specifically set Fetch Size to something like 1000, by default setting
Fetch Size to zero will cause Postgres to fetch the entire ResultSet into
memory [1]. We should probably change that default to avoid problems like
this and with other drivers (for example, Oracle's default is 10 rows which
is often inadequate).

Regards,
Matt
