This is a really minor nit, but the EXPLAIN output on binary strings is different from what I expected:

CREATE TABLE t1 (
 id INT NOT NULL PRIMARY KEY auto_increment,
 b varchar(255) not null,
 c varbinary(255) not null,
 index (b),
 index (c)
);


INSERT INTO t1 (b,c) VALUES ('a', 'a'),('b

Experience Report

I am currently ingesting a large continuous streaming data set. The most recent data is the most important data. The oldest - either by policy or by least importance needs to be aged-off. Today, we use Neo4J Community Edition. We perform a query to find nodes/relationships older than a specific date and then delete them.

The steps described in our README does not work for me: https://github.com/citusdata/citus/blob/master/CONTRIBUTING.md#following-our-coding-conventions

The main problem is that after cloning the tools repo we need to run make install from top level instead of uncrustify because many of the variables are defined at the top level.

At the very least it should have some basic guidelines such as add tests for new code changes. It should also make a mention that Scribbletune works in the browser via Tone.js as well as in the terminal, hence a new code change needs to be such that it ll work in both the places. If it cannot, then that should be mentioned with some reasoning so that we can plan for it's creation in a subsequent c

The deploy_test and queue_test go files contain a lot of repetitive and duplicated code that should be extracted into helpers.
My guesstimate is that we can save probably some 30-40% of the files. And they are more than 2k lines together. This is a sizable readability improvement.

The documentation website linked in this repository description seems to have moved. When clicking the link, it shows the question "how do you get here?".

The architecture mentioned R API support, but I was not able to find documentation about it a all. Would you consider creating some sample recipes for R?

Thanks!

Generate a unique ID for each scale activity/scan of a node group. Will be useful when trying to debug a particular set of events.
