Hi All,
I am using RPostgreSQL to pull data from Greenplum database. I have
successfully connected to the database and am using the following command
to retrieve the first 100 records from a table by the name "ad_data_new"
s <- dbSendQuery(con, "select * from ad_data_new limit 100")
This is taking more than 15 minutes to execute. The original table has
~100,000 rows. At the current rate, it wouldn't be feasible to pull the
data into R using the above command.
Any suggestions on improving the performance ? Or do you experience the
same performance as well ?
