actual records. This can give you an accurate measurement of the ODBC
performance, removing the bottleneck of the disk.

Hi All,
I am trying to come up with a query which returns a given

rows
without having a real table on Storage
What we learned through our research/experiments for doing performance test
for Drill ODBC, you get the best throughput when Solid State Drive EC2
instances such as m3,xlarge are used to form the HDFS.
It might be because of using S3 as your file system.
We have done a similar experiment loading data to HDFS on m1.xlarge
machines. A query profile analysis of the experiments showed reading from
magnetic storage on m1.xlarge machines was the bottleneck. Hence we
switched to m3.xlarge instances

Hi everyone,
I am wondering if you could help me stop the drillbit in MapR sandbox as
it
keeps starting again by default.
I build Drill from source from github and want to start it but the

Hi Team Drill!
While performing performance testing on Drill clusters on AWS EMR, with
TPC-H data of scale factor 100, I observed the results for a cluster of 3
nodes are similar to a cluster of 13 nodes. Hence, I am investigating how
the query is being carried out and which part of the query
much was assigned to a thread to complete
the operation. A simple scan operation doesn’t require that much memory vs
joins and other functions than can require much more memory
