We're excited to be back and pleased to say this event is being sponsored by [pgMustard](https://pgmustard.com). On the talks front, we have **Anton Borisov and Vlad Bokov** from Fresha who will take us through how they recently upgraded their fleet with zero-downtime. We will then host our first ever debate, on a topic to be determined! WHERE Join us at **Doggett's Coat and Badge on 14 April from 18:30.** PROGRAM 18:30 Welcome 19:00 Swapping the Elephant Without Breaking the Room: Zero-downtime Major PG upgrades in practice (Anton Borisov and Vlad Bokov, Fresha) - abstract below 19:45 Sandwiches and bar snacks (paid for by our sponsor) 20:00 Debate — topic TBD ABSTRACT **Swapping the Elephant Without Breaking the Room: Zero-downtime Major PG upgrades in practice** Upgrading PostgreSQL across hundreds of production databases without downtime sounds impossible, especially when logical replication slots, Debezium CDC pipelines, and outbox event streams are in play. At Fresha, we faced exactly that: mission-critical workloads still on PostgreSQL 12, and no safe way to reach 17 without freezing the business. This talk walks through how we designed and automated a blue-green upgrade framework using logical decoding, controlled WAL overlap, and connector orchestration. We’ll dive into how Debezium connectors, replication origins, and PgBouncer pools were coordinated to guarantee continuity for both CDC and outbox topics, with rollback and dry-run modes built in. Attendees will learn practical techniques for: * Orchestrating zero-downtime Postgres major upgrades on RDS or self-managed clusters * Managing replication slots and Debezium connectors safely across clusters * Handling sequence alignment, WAL overlap, and connector state transitions * Designing reversible, testable database cutovers This is a practical session from real production experience: no magic tools, just PostgreSQL internals, Debezium, careful planning, and a few well-placed bash scripts. SPEAKERS **Anton Borisov** architects real-time data systems centered on PostgreSQL. At Fresha, he designs zero-downtime migrations, Debezium-based CDC pipelines, and overall data strategy integrating Postgres with Kafka and Flink. His work spans query planning analysis, partitioning and indexing, autovacuum and bloat optimization, and performance tuning under high-concurrency workloads. He also builds downstream lakehouse integrations with Iceberg, Paimon, and StarRocks. Anton publishes technical deep-dives on PostgreSQL internals, streaming infrastructure, and production reliability at medium.com/@borzoniusy **Vlad Bokov** is a Staff Engineer at Fresha working on systems behind activity feeds and communication between partners and customers. He deals with what breaks at scale: PostgreSQL under heavy write load, WAL bottlenecks, replication issues, Kafka pipelines, and zero-downtime migrations. Most of his work is about making production systems behave: fixing what is slow, unstable, or too expensive, and making trade-offs that hold up under pressure. He works across Snowflake, StarRocks, PostgreSQL, Elasticsearch, and Redis, and is currently exploring newer streaming approaches, including Apache Fluss, for real-world workloads. *** THE OFFICIAL BITS The meet-up abides by [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/).

Join us as we get together to get together to help those in need at this CMG Gives Back event! We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “create a better world” by helping serve those in need. Here are complete details and our plan for this event: FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. For this event, our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces. PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:20am and wear closed-toe shoes and long pants. LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1 (in the back of the building), indicated in the attached map. On-site parking in the adjacent lot and street parking is available in the surrounding area. Below are some links / attachments with additional info/details: IMPORTANT REMINDER: Our group will be providing all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please try to update your RSVP no later than one week prior to the event. With few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. Our Partner Agency for this event is Lutheran Social Services! A huge THANK YOU to all of YOU for volunteering at this (and any of our previous) CMG Gives Back events! Should be a good/fun/meaningful time together, Dan

Who else is ready to sit outside? Join us for a casual chat over coffee & tea at Grandview Grind! Come out and meet some new people, enjoy your favorite drink, and make some new friends!

Meet at Wolfe Park parking lot by tennis courts. We willl walk along Alum Creek trail, through Jeffrey Mansion Park then along Bexley neighborhood and back. Optional lunch at Trolley District.

This is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance. Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology Life Improvement Center of Central Ohio.
