We are interested in adding support to import records from Monetdb tables in the ETL we are developing. We have performance issues when executing queries like:

select col0, col1, ... coln from <table>

on tables with a large number of records. What I am concerned about is the time spent upfront, before the first record is retrieved: once records become available we can start processing them.

For example, on my machine, executing a executing a select * from <table> query on a 68 million records table takes around 24 seconds for the query to execute, before it is actually possible to start retrieving records from the server response.

Queries are submitted via the JDBC driver.

Is there a more efficient way of streaming records from a table ?

Thanks,

Best regards,
