Intermix is an analytics platform that instruments Amazon Redshift to improve performance, reduce costs, and eliminate downtime. Our SaaS product intelligently tunes databases in the cloud, provides deep analytics, recommendations, and predictions, so companies don't have to hire DBA experts, throw money at performance problems, or deal with slow queries.

Getting Started

These instructions will help set up your environment to execute these scripts locally.

Prerequisites

The following are required to create a local development instance.

  • Python 2.7.6+ (Python 2.7.12 is recommended)
  • PIP Package manager for Python

To install the prerequisites:

pip install -r ./requirements.txt

Configuration Settings

The file settings_local.py contains sensitive data for your environment. Simply rename the file settings_local.py.default and edit the file accordingly.

Utilities

Vacuum

The following utility will generate a bash script that can be executed to reclaim deleted space and update row statistics on all tables in your cluster. Only tables that have space to be reclaimed will be touched.

The utility will first call the Intermix API to retrieve a list of tables whose statistics are > 10% stale, and then generate the script and include all necessary information to log into your Redshift cluster. When you run the script, you will be prompted for your user password.

Note: You must first create a settings_local.py file and enter information that will be used to generate the script.

This utility will not access your cluster, it will simply generate a bash script.

Usage

vacuum.py

Generates a script to execute 'vacuum delete only' and 'analyze' on tables that require it.

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        Enter a filename or "STDOUT"

Example

python ./vacuum.py -o foo.sh

Then execute the bash script with

bash ./foo.sh

User Analytics

Will output a CSV to STDOUT that contains user statistics for the past 7 days.

Usage

user_analytics.py

Generates a CSV for per-user statistics including query counts, latency, memory usage, and more.

<no optional arguments>

Example

python ./user_analytics.py
