Hello,
it's normal that only the indexes on one table is used during an inner
join ?
for exemple :
table a
ID = pk_index
DATE = index a_date = selectivity : 0.1
NAME = index a_name selectivity :0.1
table b :
REFIDA = fk_index
REFPRODUIT = index b_produit = selectivity : 0.2
NAME = index
= 0.0024333
B_IDX1 = 0.999
B_IDX2 = 0.999
B_IDX3 = 0.5
B_IDX4 = 0.999

Hello everyone,
We've faced some big problems which prevent us to release alpha4 SDK,
so, I think we own you some explanations why we delay it that much.
First problem we've encountered it

problems (hang connection).
An exemple a request retrieve 2000 rows with two blob columns :
