Hi,
I contribute to node-firebird provider and I have question about the way to
retrieve blob.
First it works well, but I think the way is not good and could cause future
problems (hang connection).
An exemple a request retrieve 2000 rows with two blob columns :
Today in the node provider, in this case :
1) Write on the socket 2 x 2000 op_open_blob
2) Then Write 2 x 2000 op_get_segment
On the socket we obtain that
1) first write => 4000 op_open_blob
2) first read => obtain 4000 blob handle
3) write 4000 op_get_segment
….
In some case the fb server no accept write on this connection and no drain
event is emitted so maybe there is a problem in this way of doing.
My question is, for you this way of doing is supported ?
The normal way for me is to get blob one by one, isn’t it ?
If I understood you correctly - yes.
