Arg, very tough call here. I want to use AWS Keyspaces (Cassandra). I like it so much more than Dynamo.

But the Swift Cassandra driver (made by Apple!) has two serious limitations with Keyspaces, both of which are unrealistic for me to fix myself. And I'm probably the only person doing this.

NGC 6888: The Crescent Nebula

NGC 6888, also known as the Crescent Nebula, is a about 25 light-years across, a cosmic bubble blown by winds from its central, massive star. This deep telescopic image includes narrowband image data, to isolate light from hydrogen and oxygen atoms. The oxygen atoms produce the blue-green hue that seems to enshroud the nebula's detailed folds and filaments.

Visible within the nebula, NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years. In fact, the Crescent Nebula's complex structures are likely the result of this strong wind interacting with material ejected in an earlier phase. Burning fuel at a prodigious rate and near the end of its stellar life, this star should ultimately go out with a bang in a spectacular supernova explosion. Found in the nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years away.

Meet the dazzling Ocellated Turkey (Meleagris ocellata). This bird is a flashier relative to the typical Wild Turkey (Meleagris gallopavo). It sports a lustrous coat of colorful feathers and a blue head dotted with vivid orange bumps. The word โ€œocellatedโ€ in its common name refers to the eye-like markings on this turkeyโ€™s tail, which are similar to those found on a peacockโ€™s plumes.

This spectacular bird's gobble begins with a series of low frequency thumpsโ€”similar to the sound of a starting engine!

Image Description
A photo of an Ocellated Turkey. It is facing the viewer, head turned away. It is covered in shimmering feathers, and has a blue head covered in bright yellow lumps. And ocellated tail.
