------------------------------------
h2. Test Case Setup
The following results are tested with:
* a single 4 core 8GB RAM Centos 7 VM on my Macbook Pro laptop
* openjdk version "1.8.0_181"
* HBase 2.1.0 single node
* Knox 1.1.0 without SSL
* data set - 1 million rows generated
** rowkey - 1-1000000
** column family:qualifier - a:a
** value - hello world
* scan limit to first 50 thousand, 100 thousand, and 200 thousand rows
Create table
{code:java}
curl -vi -XPUT -H "Accept: text/xml" -H "Content-Type: text/xml" -d '<?xml
version="1.0" encoding="UTF-8"?><TableSchema name="testdata"><ColumnSchema
name="a" /></TableSchema>' "http://hbase.vagrant:8080/testdata/schema"{code}
Testing commands
* HBase shell
**
{code:java}
time echo "scan 'testdata', {'LIMIT' => 100000}" | /opt/hbase-2.1.0/bin/hbase
shell >/dev/null{code}
* HBase Rest
**
{code:java}
time curl -u admin:admin-password -s -H "Accept: application/json"
'http://hbase.vagrant:8080/testdata/*?limit=100000' >/dev/null{code}
* HBase Rest with Knox
**
{code:java}
time curl -u admin:admin-password -s -H "Accept: application/json"
'http://hbase.vagrant:8443/gateway/sandbox/hbase/testdata/*?limit=100000'
>/dev/null{code}
> HBase "scan" performance evaluation

> Key: KNOX-1525
> URL: https://issues.apache.org/jira/browse/KNOX-1525
> Project: Apache Knox
> Issue Type: Task
> Reporter: Kevin Risden
> Assignee: Kevin Risden
> Priority: Major
> Fix For: 1.2.0
>
>
> While looking at WebHDFS performance in KNOX-1221, I decided to look a bit
> more into performance for common use cases. HBase performance is another area
> that could use some research.
> Use "scan limit" to get a comparison of raw return speed from HBase Rest.
> This should show how fast results can be streamed through HBase Rest and
> Knox. Compare the results to "hbase shell" since this will render the data
> directly from HBase through the typical HBase shell. This should give
> comparisons for the difference in overhead between HBase, HBase Rest and
> HBase Rest with Knox.
