Born of the void between states of being, the Phoenix Force is a child of the universe. It is the nexus of all psionic energy which does, has, and ever will exist in all realities of the Omniversethe Guardian of Creation, and a de-facto guardian of the M'Kraan Crystal.

The Phoenix is among the most feared beings in the entire universe - having the power to cut and regrow any part of the universe, as well as destroy it entirely, which is part of the Phoenix's purpose: Recent interventions of the Phoenix suggest that "what doesn't work" is what has become stagnant instead of naturally evolving.

The Phoenix intervened, bonding with one of the aliens of that world and breaking the spell, and purging the world. The Phoenix Host had five "Lights", disciples of sorts that helped the host control the infinite power of the Phoenix.

At first, the Phoenix Force was a formless mass of energy, but a long time ago, it came to Earth and met a magician named Feronwho worshiped the legendary Phoenix, and whose daydream-like visions prompted the entity to adopt the firebird form it has today. Feron asked the Phoenix to help him by lending its energy to project a stone pillar, which resembled a lighthouse, across the Multiverse.

In Earth the pillar became the lighthouse base for the British superteam, Excalibura team its future host Rachel Summers herself would join. Rook'shir's rampage led to the Phoenix Force being feared and demonized by the Shi'ar Empirewho went to extreme lengths to exterminate all bloodlines deemed compatible with the cosmic entity.

Jean Grey Earth The Phoenix Force left Earth, but was called back when it felt the mind of a human transcend the physical realm, a mind that resonated with the Phoenix's energy.

The Phoenix Force responded to Jean's anguish and telepathic calls for help, as she was dying aboard the space shuttle. It appeared before her, shaping its form and consciousness after Jean's own.

What Jean most wanted was to save the lives of the X-Men and herself. Jean held onto the Phoenix Force's arm and fell into a coma-like state.

Simultaneously, the Phoenix Force fully took on the form, memories, and personality of Jean Grey, by absorbing a portion of her consciousness. It was also responsible for casting Jean into a coma-like state and placing her within a cocoon-like construction, which rested for years at the bottom of Jamaica Bay, while her injuries healed completely.

Thus, the Phoenix Force fulfilled its pledge to Jean.

During this time, the Phoenix scanned the human member and leader of the Starjammers to learn it was Cyclops ' long thought dead father, Christopher Summers.

The Phoenix and the Beast ended up separated from the other X-Men, each group mistakenly believing the other to have died.Write amplification is one of them and using either WiredTiger with MongoDB or Percona TokuMX is a very simple way to fix the issue.

Compliant Database DevOps and the role of DevSecOps DevOps is becoming the new normal in application development, and DevSecOps is now entering the picture. Note: A 32GB SSD with a mediocre 10x write amplification factor, a standard write/erase cycle, and 10GB of data written per day, would get an 8 years life expectancy.

It gets better with bigger SSDs and modern controllers with less write amplification.

While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them. Many of those names are known only to professionals.

However, due to popularization of science, they gradually become part of. During the garbage collection, wear-leveling, and bad block mapping operations on the SSD, the additional space from over-provisioning helps lower the write amplification when the controller writes to the flash memory.
