Good afternoon,

I have 2 questions :

- 1st question
I have a csv file with 300000000 million lines.

when I load it in a MonetDB table, it takes more than 16 hours, whereas in Oracle it only takes 15 minutes. Where is the problem?
I use mclient as follows :?
mclient -u user1 -d demo -ims -s " COPY 300000009 RECORDS INTO LINEORDER FROM STDIN USING DELIMITERS '|','\n'" - < D:\SSB\LINEORDER.tbl

?for information I use :

MonetDB5
Windows
Memory : 16 Go
There are two constraints : primary key and foreign key on the table prior to loading data?

2nd question :

how inner joins are made in MongoDB?

cordialy.
