We would like to avoid confusion like we have in webpack-contrib/webpack-bundle-analyzer#185

We could document statsFilename and reportFilename options allowing the use of an absolute file path like /path/to/folder so that people would know it's supported.

Let us know in this issue if you would like to contribute to this!

Describe the bug

It's possible to create a stream or table with no value columns using a CREATE TABLE or CREATE STREAM statement. No error is returned.

However, if you try and use the stream or table in a downstream CREATE TABLE AS or CREATE STREAM AS statement you get a error message.

i.e. the table/stream created with no columns isn't useful.

To Reproduce

Hey everyone!

mapd-core-cpu is already available on conda-forge (https://anaconda.org/conda-forge/omniscidb-cpu)

now we should add some instructions on the documentation.

at this moment it is available for linux and osx.

some additional information about the configuration:

1. for now, always install omniscidb-cpu inside a conda environment (also it is a good practice), eg:

Create a new notebook, add cells containing @__FILE__ and @__DIR__. Then move the file from the default location to a new name and location. For fun, add additional cells containing @__FILE__ and @__DIR__. Note that re-running the cells which display the out-of-date results does not cause them to update their results.

Introduction

Background

To ensure Oppia remains available and high-quality for our students, we run end-to-end tests on all PRs to check that the site's functionality hasn't been broken. Recently, these tests have begun failing non-deterministically. This frustrates developers and slows their work by incorrectly indicating that developers’ changes are faulty. The goal of this issue is t
