💭 Talk Abstracts:One Does Not Simply Query a Stream - Viktor Gamov, Principal Developer Advocate, ConfluentStreaming data with Apache Kafka® has become the backbone of modern applications. While streams are ideal for continuous data flow, they lack built-in querying capabilities. Unlike databases with indexed lookups, Kafka’s append-only logs are designed for high-throughput processing—not for on-demand queries. This necessitates additional infrastructure to query streaming data effectively.Traditional approaches replicate stream data into external stores: relational databases like PostgreSQL for operational queries, object storage like S3 accessed via Flink, Spark, or Trino for analytics, and Elasticsearch for full-text search and log analytics. Each serves a purpose—but they also introduce silos, schema mismatches, freshness issues, and complex ETL pipelines that increase system fragility.In this session, we’ll explore solutions that aim to unify operational, analytical, and search workloads across real-time data.We'll demonstrate stream processing with Kafka Streams, Apache Flink®, and SQL engines; real-time analytics with Apache Pinot® ; search capabilities with Elasticsearch; and modern lakehouse approaches using Apache Iceberg® with Tableflow to represent Kafka topics as queryable tables. While there's no one-size-fits-all solution, understanding the tools and trade-offs will help you design more robust and flexible architectures.

A Practical Approach to Real‑Time SQL Data Indexing in Elasticsearch - Mangesh Walimbe (Application Architect)SQL databases are designed to store and manage large volumes of structured data, but they are not optimized for high‑speed search and analytics. Elasticsearch, by contrast, provides powerful indexing and near real‑time search capabilities, making it a strong complement to traditional relational systems. Ensuring that SQL data is continuously available in Elasticsearch, however, can be a complex and time‑consuming process. This presentation outlines a streamlined approach for processing, filtering, and ingesting SQL database records into Elasticsearch using Logstash pipelines, based on practical implementation experience.
