Join us on May 7th from **6:00pm** for a Data Streaming meetup hosted by **[Fresha](https://www.fresha.com/)**! 📍**Venue:** **Fresha** The Tower, 207 Old Street London, EC1V 9NR 7th Floor **PLEASE bring your PHOTO ID and REGISTER with your First and Last Name, Email. Thanks!** **DOORS CLOSE AT 7PM FOR SECURITY.** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:00pm: Anton Borisov, Principal Data Engineer, Fresha & Nicoleta Lazar, Sr. Data Engineer, Fresha * 7:00pm - 7:30pm: Olena Kutsenko, Staff Developer Advocate, Confluent * 7:30pm - 8:00pm: Tom Scott, Founder & CEO, Streambased * 8:00pm - 9:00pm: Q&A Networking 💡**Speaker One:** Anton Borisov, Principal Data Engineer, Fresha & Nicoleta Lazar, Sr. Data Engineer, Fresha **Title of Talk:** Apache Fluss: Streaming Storage for Real-Time Analytics **Abstract:** Apache Flink has largely solved streaming computation, but state management remains a bottleneck. Operator state—often backed by RocksDB—is scoped to individual jobs, making it hard to share state across pipelines without re-emitting it through systems like Apache Kafka. This leads to expensive joins and added operational complexity. Apache Fluss (incubating) addresses this by externalizing state into a streaming storage layer backed by S3. Its PrimaryKey tables act as upsertable key-value stores with replicated changelogs, enabling shared state tables accessible from Flink, Spark, or native clients. With Flink 2.1’s Delta Join, both sides of a join can perform lookups against Fluss-managed indexes—eliminating the need for large join state altogether. In this talk, we’ll introduce Fluss, show key use cases like CDC enrichment and bilateral joins, and share lessons from running it in production on EKS —including the trade-offs and rough edges we encountered. 💡**Speaker Two:** Olena Kutsenko, Staff Developer Advocate, Confluent **Title of Talk:** The journey of a record from Kafka topic to analytics table **Abstract:** Modern data platforms increasingly rely on streaming systems like Apache Kafka as the source of truth—but turning event streams into reliable, queryable analytics tables is far from trivial. This talk explores what really has to happen when moving data from a Kafka topic into an Apache Iceberg table. Beyond simple ingestion, we will walk through the essential steps: schema evolution, data normalization, partitioning, exactly-once guarantees, late-arriving events, and table maintenance. Using Confluent Tableflow as one concrete example, we will examine how these challenges can be addressed in practice. Along the way, we will compare alternative approaches—such as Kafka Connect sinks, stream processing pipelines, and custom ingestion frameworks—to highlight trade-offs in correctness, latency, and operational complexity. The goal is not to promote a single solution, but to provide a mental model for designing robust streaming-to-lakehouse pipelines, helping you understand what matters regardless of the tooling you choose. **Bio:** Olena is a Staff Developer Advocate at Confluent and a recognized expert in data streaming and analytics. With two decades of experience in software engineering, she has built mission-critical applications, led high-performing teams, and driven large-scale technology adoption at industry leaders like Nokia, HERE Technologies, AWS, and Aiven. A passionate advocate for real-time data processing and AI-driven applications, Olena empowers developers and organizations to use the power of streaming data. She is an AWS Community Builder, a dedicated mentor, and a volunteer instructor at a nonprofit tech school, helping to shape the next generation of engineers. As an international speaker and thought leader, Olena regularly presents at top global conferences, sharing deep technical insights and hands-on expertise. Whether through her talks, workshops, or content, she is committed to making complex technologies accessible and inspiring innovation in the developer community. 💡**Speaker Three:** Tom Scott, Founder & CEO, Streambased **Title of Talk:** *Infinite Kafka? Rethinking Retention with Iceberg* **Abstract:** Apache Kafka is designed for high-throughput, low-latency event streaming, not cost-efficient long-term storage. Yet we constantly see cases like event sourcing, audit/compliance, and large-scale reprocessing forcing that pattern onto it. As retention increases, costs grow linearly to support edge cases, one-time runs, and “checkbox” use cases. Can Iceberg help here? In this talk, Tom explores a hybrid architecture that separates hot and cold data while preserving Kafka’s log semantics. Using a combination of Kafka and Apache Iceberg, he demonstrates how to extend Kafka into low-cost object storage, enabling effectively unlimited retention without sacrificing performance or access patterns. The result is a unified log that supports both real-time processing and long-term replay, removing the traditional trade-off between cost and capability in Kafka-based systems. **Bio:** Long-time enthusiast of Kafka and all things data integration, Tom has more than 15 years of experience in innovative and efficient ways to store, query, and move data. Tom is currently CEO at Streambased, a company focused on unifying operational and analytical data estates into a single, consistent, and efficient data layer. \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

‘*I can understand myself only in the light of inner happenings. It is these that make up the singularity of my life, and with these my autobiography deals*’ Carl Jung An eye-opening biography of one of the most influential psychiatrists of the modern age, drawing from his lectures, conversations, and own writings. In the spring of 1957, when he was eighty-one years old, Carl Gustav Jung undertook the telling of his life story. Memories, Dreams, Reflections is that book, composed of conversations with his colleague and friend Aniela Jaffé, as well as chapters written in his own hand, and other materials. Jung continued to work on the final stages of the manuscript until shortly before his death on June 6, 1961, making this a uniquely comprehensive reflection on a remarkable life. Look forward to discussing this with you at the Metronome!

**Fundamentally by Nussaibah Younis** ***Shortlisted for Women's Prize 2025*** *"By normal, you mean like you? A slag with a saviour complex?'* Nadia is an academic who's been disowned by her puritanical mother and dumped by her lover, Rosy. She decides to make a getaway, accepting a UN job in Iraq. Tasked with rehabilitating ISIS women, Nadia becomes mired in the opaque world of international aid, surrounded by bumbling colleagues. Sara is a precocious and sweary East Londoner who joined ISIS at just 15. Nadia is struck by how similar they are: both feisty and opinionated, from a Muslim background, with a shared love of Dairy Milk and rude pick-up lines. A powerful friendship forms between the two women, until a secret confession from Sara threatens everything Nadia has been working for. \*\*\* Chapters & Conversations is a space for fiction lovers to connect over great stories and lively chats! Whether you’re into literary fiction, contemporary novels, or fantasy worlds, we’re here to explore it all together. We’re hoping to meet fellow bookworms who enjoy getting lost in a good story and are open to sharing thoughts, laughs, and recommendations. At each event, we’ll dive into a chosen book, chat about characters, themes, and twists - above all, it’s about community, curiosity, and a shared love of reading! Stasia and Yana:)

We love a good chat. Come and join us at Table 45

In our first meeting of May, we discuss Brandon Taylor's *Real Life.* Shortlisted for the Booker Prize in 2020, the novel was the much-lauded debut for the Alabama-born writer. 'Deftly zooming in and out of focus, *Real Life* is a deeply affecting story about the emotional cost of reckoning with desire, and overcoming pain.' (Book jacket) 'A campus novel told from the perspective of a Black student, Taylor’s powerful tale embraces themes of grief, desire and alienation in rich, eloquent prose.' -Waterstones https://www.goodreads.com/book/show/46263943-real-life We will discuss the Real Life in the Real Greek - Bankside. So come along for some tasty Greek fare on a Sunday afternoon as we dive into this fascinating premier. N.B. We will be charging an event fee of £3, non-refundable, to discourage no-shows and contribute to the running costs of the group. Please only sign up if you intend to come along as space is limited to make for an effective discussion!

In these sessions, we will start to cultivate a relationship with our breath, so that we are able to work WITH it and USE it day to day, developing an inner sense of presence, self connection and resilience so that we are better equipped to navigate 'life'. We will also explore techniques to deepen and expand our relationship with our selves, others and with our past through our breath, and experience a guided conscious connected breathwork journey to release emotional blockages and tap into our inner wisdom for clarity, healing and transformation. You may experience a profound shift in your consciousness, deep inner healing and letting go, and a (re)connection with your true, authentic self. This event is ideal for those interested in self-help and self-evolution, energy healing, and exploring the depths of their spiritual nature. These workshops offer you a supportive space to let go of limiting beliefs, rejuvenate your energy, and awaken to the full potential of your being. Whether you are new to breathwork or have been practicing for years, this session will offer you a unique opportunity to dive deep into the healing power of your breath About Kate - Kate first experienced the incredible healing and transformational power of her own breath in 2016. Blown away by the insight, clarity and deep inner healing that unfolded in just one session, she went on to train with Transformational Breath and to then get certified as an Alchemy of Breath Facilitator in 2018. She has explored many modalities including Rebirthing and Holotropic, but primarily follows the Alchemy of Breath philosophy to breathwork, taking an intuitive approach to holding space for whatever wants to unfold and encouraging breathers to listen first and foremost to their own body and intuition, and to allow their breath to guide them wherever it is they need to go. Kate believes that we are our own healers, and that if we can simply breathe – here – now – and be willing and open to receive – then we can connect with that inner knowing, our eternal wisdom, and find all the answers we are looking for, all of the resolution we crave, and all of the guidance we need, to step forward in alignment with our true self, resourced and able to live our very best life. **General House keeping - Please read!** Please kindly make payment by bank transfer of £15 upon booking to secure your spot directly as spaces are limited to 5 per session.

Join us for lunch/tea at Asterisk Supper Club to discuss our May book "Under the Oak Tree" by Suji Kim Lady Maximilian is the daughter of the powerful Duke Croyso, but she is rarely allowed outside her family’s sprawling castle for fear that her stutter will tarnish their noble name. When she is forced to marry Sir Riftan, a lowborn knight caught in one of her father’s schemes, Maxi doesn’t dare hope for happiness, let alone love. Her stumbling communication and his gruff manner sour their relationship before it can begin, and Riftan leaves without a word the morning after their vows are exchanged. Now, three years after their disastrous wedding night, Riftan has returned as a war hero. To Maxi’s surprise, despite rumors that he was offered marriage to Princess Agnes, a beautiful and renowned sorceress, Riftan still wants Maxi for his wife. And when he comes to claim her, his longing becomes a desire that bewilders Maxi, even as she is overcome by the scorching heat that Riftan’s presence ignites within her. As she learns to navigate the intricacies of her new life, Maxi will find herself and her courage, and discover that she is anything but powerless.

Join us as we discuss our June pick: Metal Slinger by Rachel Schneider! Book description: Even though she's not one of them, Brynn has spent her life among the Alaha, training to be a guard and waiting for the chance to attend the annual market hosted by the Kenta–the very same people who exiled her adopted community to a life at sea. Going to the market is a rite of passage eagerly anticipated by all young guards, but Brynn does not anticipate breaking a century-long peace treaty while there. Nor does she plan for the intense encounter with an enemy soldier that now threatens to unwind the fragile coexistence between their people–and everything Brynn once believed about herself to be true. Brynn's loyalty to the Alaha is tested when the truth of her identity is brought to light by this soldier who's taken an oath to bring her back to where she belongs. Narrowly escaping death on the violent high seas, Brynn's connection to the Alaha is further tested when she learns about the world of magic she's been denied. She was once certain of her fate and where she belonged, but the dark, knowing eyes of this stranger have her questioning everything, including her heart. Packed with knife fights and seafaring adventure, METAL SLINGER is the smash-hit start to the romantic fantasy duology, the Fire & Metal series
