absolutely unintelligeable meme I made during bootcamp lecture this morning

[regainingparadise]

If I could make any change to Ao3, I would:

Distinguish between "major" and "minor" tags for characters/relationships, so that it's clear when a particular relationship is the whole point of a fic and when a particular relationship is merely incidental to/present in the fic. This would make filtering to find the desired type of fic much easier

Create a separate metadata field for canon-ness, with standardized options for "Canon Compliant" "Canon Divergent," and common Alternate Universes (i.e. "Alternate Universe - Omegaverse," "Alternate Universe - Coffee Shop," "Alternate Universe - Vampires"). Many authors do include this information in their tags, but it's often buried, and because there's not a controlled vocabulary, trying to limit to or exclude based on these factors is hit or miss

The Data Migration Odyssey: A Journey Across Platforms

As a database engineer, I thought I'd seen it all—until our company decided to migrate our entire database system to a new platform. What followed was an epic adventure filled with unexpected challenges, learning experiences, and a dash of heroism.

It all started on a typical Monday morning when my boss, the same stern woman with a flair for the dramatic, called me into her office. "Rookie," she began (despite my years of experience, the nickname had stuck), "we're moving to a new database platform. I need you to lead the migration."

I blinked. Migrating a database wasn't just about copying data from one place to another; it was like moving an entire city across the ocean. But I was ready for the challenge.

Phase 1: Planning the Expedition

First, I gathered my team and we started planning. We needed to understand the differences between the old and new systems, identify potential pitfalls, and develop a detailed migration strategy. It was like preparing for an expedition into uncharted territory.

We started by conducting a thorough audit of our existing database. This involved cataloging all tables, relationships, stored procedures, and triggers. We also reviewed performance metrics to identify any existing bottlenecks that could be addressed during the migration.

Phase 2: Mapping the Terrain

Next, we designed the new database design schema using schema builder online from dynobird. This was more than a simple translation; we took the opportunity to optimize our data structures and improve performance. It was like drafting a new map for our city, making sure every street and building was perfectly placed.

For example, our old database had a massive "orders" table that was a frequent source of slow queries. In the new schema, we split this table into more manageable segments, each optimized for specific types of queries.

Phase 3: The Great Migration

With our map in hand, it was time to start the migration. We wrote scripts to transfer data in batches, ensuring that we could monitor progress and handle any issues that arose. This step felt like loading up our ships and setting sail.

Of course, no epic journey is without its storms. We encountered data inconsistencies, unexpected compatibility issues, and performance hiccups. One particularly memorable moment was when we discovered a legacy system that had been quietly duplicating records for years. Fixing that felt like battling a sea monster, but we prevailed.

Phase 4: Settling the New Land

Once the data was successfully transferred, we focused on testing. We ran extensive queries, stress tests, and performance benchmarks to ensure everything was running smoothly. This was our version of exploring the new land and making sure it was fit for habitation.

We also trained our users on the new system, helping them adapt to the changes and take full advantage of the new features. Seeing their excitement and relief was like watching settlers build their new homes.

Phase 5: Celebrating the Journey

After weeks of hard work, the migration was complete. The new database was faster, more reliable, and easier to maintain. My boss, who had been closely following our progress, finally cracked a smile. "Excellent job, rookie," she said. "You've done it again."

To celebrate, she took the team out for a well-deserved dinner. As we clinked our glasses, I felt a deep sense of accomplishment. We had navigated a complex migration, overcome countless challenges, and emerged victorious.

Lessons Learned

Looking back, I realized that successful data migration requires careful planning, a deep understanding of both the old and new systems, and a willingness to tackle unexpected challenges head-on. It's a journey that tests your skills and resilience, but the rewards are well worth it.

So, if you ever find yourself leading a database migration, remember: plan meticulously, adapt to the challenges, and trust in your team's expertise. And don't forget to celebrate your successes along the way. You've earned it!

genuinly very curious- how full is your submission backlog? i'm sure y'all get quite a few submissions pretty regularly, i'm just curious how many y'all have to sort through

Our backlog is about three weeks long, although it varies quite a bit - e.g., we get way more submissions on Sundays and Mondays since the majority of games happen on the weekend, and we also tend to get more submissions right after holidays and around the end of summer vacation / beginning of fall.

There's also a technical component due to Tumblr's.... let's call it unconventional back-end infrastructure / database schema, which has an unfortunate tendency to hide random submissions until mystical unknown criteria are met. Which is why we sometimes post quotes that were submitted months ago - they've finally been released from the depths of Tumblr's databases into our inbox.
