+
+image:events/speakers/scott-andreas.jpg[Scott Andreas,110,role=alignleft]
+*Scott Andreas* — Engineering Manager, Core Databases, Apple, Inc.
+
+Cassandra's Dynamo roots produced a database with tradeoffs that weren't
always familiar to users. This presentation puts together the puzzle pieces of
years of work in the community: Transactional Metadata, distributed
transactions, mutation tracking, flexible placements and tablets,
storage-attached indexes. Together they show what Apache Cassandra is becoming,
a normal database that works the way users expect.

+*Bernardo Botella Corbi* — Software Engineer, Apple
+
+{jira}/CASSANDRA-20854[CASSANDRA-20854^] introduced a native CPU profiler to
the Cassandra toolset. This session covers how to use it and how to read its
results, load-testing the features 6.0 is set to introduce, including Accord,
change data capture and constraints.
+
+[#sidecar]
+==== 14:20 — Automating Your Cassandra Operations With Apache Cassandra Sidecar
+
+*Isaac Reath* — Engineering Team Leader, Bloomberg +
+*Andres Beck-Ruiz* — Bloomberg
+
+Bloomberg replaced its proprietary sidecar with Apache Cassandra Sidecar. This
talk covers Sidecar's architecture and features, how it was integrated into
Bloomberg's managed Cassandra platform, the upstream contributions that made it
fit, and practical workflows you can use to automate operational tasks today.

+*Dmitry Konstantinov* — System Architect, NetCracker Technology
+
+A year of source-level optimisation work on the write path: request decoding,
data validation, coordination, memtable allocation and flushing, compaction,
and metrics collection. Includes the benchmarking setup and tooling used to
find each bottleneck, and the optimisation patterns that generalise.
+
+[#accord-protocol.cf]
+==== 16:10 — Accord: the Protocol Behind Cassandra's Multi-Shard Transactions
+
+image:events/speakers/fedor-ryabinin.jpg[Fedor Ryabinin,110,role=alignleft]
+*Fedor Ryabinin* — Postdoctoral Researcher, IMDEA Software Institute
+
+Cassandra 6.0 introduces strictly serializable multi-shard transactions that
often complete in a single WAN round trip, enabled by Accord
({cep}/CEP-15%3A+General+Purpose+Transactions[CEP-15^]), which replaces Paxos.
Rather than covering the implementation, this talk explains the protocol itself
and traces the path from Paxos to Accord, the first leaderless protocol
deployed in a widely used production system.
+
+=== Monday 12 October
+
+[#off-heap-memtables.cf]
+==== 10:20 — Fully off-heap memtables
+
+image:events/speakers/branimir-lambov.jpg[Branimir Lambov,110,role=alignleft]
+*Branimir Lambov* — Software Engineer, IBM/DataStax +
+*Kamil Leśniak* — Software Engineer, IBM
+
+Memtables are the single largest contributor to Cassandra's garbage collection
overhead. This talk describes the final stage of a long progression: a fully
off-heap memtable implementation building on the trie memtable introduced in
{cep}/CEP-19%3A+Trie+memtable+implementation[CEP-19^], and a cornerstone of the
flat key infrastructure required for
{cep}/CEP-57%3A+Flat+keys+and+trie+interfaces[CEP-57^]. Covers configuration,
measured performance impact, and the engineering behind it.
+
+[#migration-at-scale]
+==== 11:10 — 50 Clusters a Night: Lessons from Migrating 400+ Cassandra
Clusters at Scale
+
+*Carlos Rolo* — Principal Engineer Open Source, NetApp Instaclustr +
+*Piotr Walczak* — Fellow Cloud Development Engineer, Pegasystems +
+*Sebastian Machlowski* — Director of Engineering, Pegasystems
+
+Moving 400 Cassandra clusters is not 400 versions of the same problem. A
purpose-built Migration API moved up to 50 clusters in a single night with zero
downtime. This talk covers how it was designed, why production needed a
different approach from dev and QA, and the operational reality: alert storms,
platform limits, and a split-operations bug triggered by concurrency.
+
+[#tla-plus]
+==== 12:00 — Model Checking Cassandra's Transaction Protocol using TLA+
+
+*Alexandre Siret* — IMDEA Software Institute
+
+Accord ({cep}/CEP-15%3A+General+Purpose+Transactions[CEP-15^]) is a complex
leaderless protocol with multiple subtle optimisations, and it is the only
leaderless protocol deployed in a broadly used production system, which makes
correctness critical. This talk presents an effort to model and verify Accord
in TLA+: the modelling approach, the challenges, and how model checking
improved confidence in the protocol.

+==== 14:20 — Data Ingestion at Terabyte Scale with Cassandra Analytics
+
+*Serban Teodorescu* and *Bianca Stanciu* — Software Engineers, Adobe +
+*Alexandru Salajan* — Site Reliability Engineer, Adobe
+
+Rearchitecting an ingestion pipeline across 18 clusters, 8 AWS regions and
500+ instances, moving from SSTable loading to direct Spark-to-Cassandra
writes. Covers transport options, deployment challenges, cost and performance,
and a validation methodology for checking export accuracy against production
snapshots.
+

+[#fuzzing-accord]
+==== 14:20 — Model Guided Fuzzing of Accord
+
+*Stefan Stoicescu* — TU Delft, Software Engineering Research Group +
+
+Leaderless consensus achieves optimal latency at the cost of significant
complexity during fault recovery, and non-trivial linearizability bugs can
occur in Accord's recovery logic under specific failure conditions. Finding
them by standard trace-guided fuzzing is infeasible. This talk presents a
model-guided approach that maps concrete executions to abstract TLA+ states,
turning an unbounded trace-discovery graph into a usable coverage metric.
+
+[#cep-50.cf]
+==== 15:10 — Authentication Negotiation in Apache Cassandra (CEP-50)
+
+image:events/speakers/joel-shepherd.jpg[Joel Shepherd,110,role=alignleft]
+*Joel Shepherd* — Principal Software Engineer, Amazon.com
+
+Cassandra currently supports a single authenticator per node, which makes
migrating between authentication methods hard and diverse client types harder.
{cep}/CEP-50%3A+Authentication+Negotiation[CEP-50^] lets clients advertise the
methods they support while the server retains the decision. Covers the current
protocol flow, how negotiation extends it, and real implementation problems,
including mapping external identities such as AWS IAM principals to database
roles.
+
+[#analytics-workloads.cf]
+==== 16:10 — High-Performance Analytics on Cassandra: Enabling New Workloads
+
+image:events/speakers/francisco-guerrero.jpg[Francisco
Guerrero,110,role=alignleft]
+*Francisco Guerrero* and *Saranya Krishnakumar* — Software Engineers, Apple,
Inc.
+
+Analytical workloads mean full table scans and long-running pipelines that
compete with latency-sensitive production traffic. The Cassandra Analytics
library sidesteps the read/write path entirely, interacting instead with
Cassandra Sidecar for direct SSTable access and cluster metadata. This talk
covers the integration and how both projects will evolve alongside Cassandra's
emerging features.
+
+[#cql-cli.cf]
+==== 17:00 — Building a Modern CQL CLI for Apache Cassandra
+
+image:events/speakers/hayato-shimizu.jpg[Hayato Shimizu,110,role=alignleft]
+*Hayato Shimizu* — CTO, AxonOps
+
+cqlsh has long been the primary interface to Cassandra. CQLAI is an open
source alternative, Apache 2.0 licensed, aiming at fast startup, distribution
as a single binary, and no Python runtime dependency. Includes a live demo,
import and export in CSV, JSON and Parquet, and lessons from building open
source tooling around Cassandra.

+[#accord-benchmark.cf]
+==== 10:20 — Initial Performance Evaluation of Cassandra Accord with NoSQLBench
+
+image:events/speakers/youki-shiraishi.jpg[Youki Shiraishi,110,role=alignleft]
+*Youki Shiraishi* — Researcher, NTT, Inc.
+
+A code-informed benchmark study of Accord using NoSQLBench, with workloads
inspired by YCSB-style account-transfer and balance-check patterns. Preliminary
findings on how contention affects fast-path success, whether read-modify-write
transactions carry substantial overhead over read-only ones, and how much the
Ephemeral Read optimisation delivers.

+[#cep-57.cf]
+==== 10:20 — Solving tombstones and partitioning with flat keys and tries
(CEP-57)
+
+image:events/speakers/branimir-lambov.jpg[Branimir Lambov,110,role=alignleft]
+*Branimir Lambov* — Software Engineer, IBM/DataStax +
+*Christophe Bornet* — Software Engineer, IBM
+
+Manual partitioning strategy selection and the inability to sort between
partitions cause a great deal of user frustration, and are a stumbling block to
efficient materialized views and global secondary indexes. Tombstone handling
is a challenge to even experienced users.
{cep}/CEP-57%3A+Flat+keys+and+trie+interfaces[CEP-57^] addresses both through
byte-comparable key translations that flatten the key hierarchy into a single
byte sequence, combined with trie-based access structures.
+
+[#four-to-five]
+==== 11:10 — Much Ado About Nothing: Making Cassandra 4→5 Upgrades Predictable
and Low-Risk
+
+*Mariah McLaughlin* — Developer Advocate, NetApp Instaclustr +
+*Carlos Rolo* — Principal Engineer Open Source, NetApp Instaclustr
+
+Cassandra 5.0 brings changes worth upgrading for, and enough architectural
change that a naive rolling upgrade carries real risk, particularly for
clusters with heavy secondary index usage or customised compaction. This talk
covers per-cluster assessment, staged rollout with validation checkpoints,
preserved rollback options, and where teams tend to go wrong.
+
+[#zstd-dictionary]
+==== 12:00 — Zstd dictionary compression
+
+*Stefan Miklosovic* — Software Engineer, NetApp
+
+Zstd has been Cassandra's go-to compression algorithm since 4.0. Dictionary
compression, implemented under
{cep}/CEP-54%3A+ZSTD+with+Dictionary+SSTable+Compression[CEP-54^] and available
in 6.0, can improve the compression ratio significantly further and reduce
storage cost accordingly. An overview of the solution, how it is used in
practice, and which data profiles suit it.
+
+[#zero-trust-mtls.cf]
+==== 14:20 — Running Apache Cassandra in a Zero Trust Environment with Mutual
TLS
+
+image:events/speakers/francisco-guerrero.jpg[Francisco
Guerrero,110,role=alignleft]
+*Francisco Guerrero* — Software Engineer, Apple, Inc.
+
+Zero Trust rejects the assumption that traffic inside a network boundary can
be trusted. This talk covers running Cassandra, Cassandra Sidecar and Cassandra
Analytics under a strict Zero Trust model with mutual TLS: configuration across
internode and client-to-node communication, certificate identities as the basis
for authentication and authorization, certificate rotation, and migration from
password-based authentication.
+
+[#cep-38.cf]
+==== 15:10 — CEP-38: The Management Port Decision: A Live Architecture
Trade-off in Apache Cassandra
+
+image:events/speakers/maxim-muzafarov.jpg[Maxim Muzafarov,110,role=alignleft]
+*Maxim Muzafarov* — Open-source Software Engineer
+
+Cassandra management has always been fragmented across JMX, REST and nodetool,
each requiring its own implementation of every operation.
{cep}/CEP-38%3A+CQL+Management+API[CEP-38^], accepted in October 2025,
introduces a unified CQL-based management API. This talk walks through the port
decision: why sharing port 9042 proved impossible, what a dedicated port costs
operationally, and how the execution model enforces what is permitted. Ends
with a live demo of registering and executing a n [...]
+
+[#cep-59.cf]
+==== 16:10 — CEP-59: Graceful Disconnect — Draining Client Connections During
Cassandra Node Shutdown
+
+image:events/speakers/jane-he.jpg[Jane He,110,role=alignleft]
+*Jane He* — IBM
+
+Rolling restarts are routine, but they can still look disruptive from the
client side: drivers ignore topology DOWN events, and existing mechanisms only
signal per request, so drivers keep sending until connections fail.
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=406619103[CEP-59^]
adds an in-band protocol event letting a node tell clients it intends to
close, turning abrupt failure into controlled draining. Includes a
demonstration of the behaviour before and after.
