+The release of Apache Cassandra 4.0 has opened the floodgates to new feature
proposals. Many feature ideas have been approved and are in development such as
a cluster and code action simulator and support for general-purpose transaction
support while others, such as Storage Attached Indexing, are being discussed.

https://lists.apache.org/thread.html/18c76129a4fe6785a51dad7500e04ee13a407a7f7ac5c8f9a3d83c87%40%3Cdev.cassandra.apache.org%3E[frozen,window=_blank]
to enable project committers to focus on making 4.0 the best-tested and most
reliable major release right out of the gate.
+
+The community has invested in cutting-edge methodologies that were used at
scale to exercise edge cases in the largest Cassandra clusters, and after
extensive testing and validation, 4.0 GA was released on 26 July 2021.
+
+With a quality baseline for releases in place for future versions, the project
is again accepting proposals for new features. The Cassandra Enhancement
Process
(https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=95652201[CEP,window=_blank]),
similar to some other Apache projects, was established last year and now makes
CEPs the preferred route for broad or disruptive changes to the Cassandra
codebase. This structured approach opens the door wide to exploring,
discussing, an [...]
+
+*A host of new enhancements*
+
+Already we have seen CEPs approved and in development, such as:
+
+*
https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-10%3A+Cluster+and+Code+Simulations[Cluster
& code action simulator,window=_blank] - a facility for simulating operations
on clusters that enables repeatable but pseudo-random exploration of state
space and correctness testing. This will bolster the already formidable testing
capabilities the Cassandra community offers and represents a true advancement
in the state-of-the-art for distributed systems testing.
+*
https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-13%3A+Denylisting+partitions[Denylisting
partitions,window=_blank] - when operating Cassandra in production, reading
certain partition keys can cause undesirable effects on the entire node or
within the cluster. This denylisting feature is another critical tool in the
operator toolbox to reduce the impact of unexpected or unhealthy client reads
and writes on specific partitions. This feature will also prevent DDOS attacks
where [...]
+*
https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-15%3A+General+Purpose+Transactions[General-purpose
transactions,window=_blank] - a popular feature in community discussion which
has been quickly approved, this CEP, when implemented, will be a major feature
for many users as it will deliver the first-ever database that supports
general-purpose transactions without the recognized trade-offs seen in other
databases, such as scalability bottlenecks or the lack of strong consistenc
[...]
+*
https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-11%3A+Pluggable+memtable+implementations[Memtable
pluggable memtable storage,window=_blank] - this is a CEP with potentially the
broadest impact for more advanced use cases such as persistent memory. This
feature is also a crucial first step in exploring using alternative storage
engines within Cassandra, optimized for specific workloads. Instagram has
already shown early promise with this idea by adding RocksDB as a storage
engine.
+*
https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-14%3A+Paxos+Improvements[Paxos
improvements,window=_blank] - a feature that builds on the cluster simulation
CEP and improves the performance of lightweight transactions (LWTs). This type
of transaction is used to guarantee that the data most recently written is
considered before a read, which, in turn, ensures a high level of consistency
for any decisions you want to make on data and allows linearizable access by
concurrent use [...]
+*
https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-16%3A+Auth+Plugin+Support+for+CQLSH[Auth
Plugin Support for CQLSH,window=_blank] - CQLSH, the included CLI tool, is
important and useful, but, unfortunately, lacks the same support for different
authentication methods. This will allow anyone using third-party-provided
plugins like LDAP, Kerberos, and Sigv4 to be able to continue to use CQSLH.
+
+Many other CEPs are being proposed and nearing a vote for approval, such as:
+
+*
https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-7%3A+Storage+Attached+Index[Storage
Attached Indexing (SAI),window=_blank] - this is another CEP nearing a vote,
which is designed to replace the original secondary indexing. This will enable
users to index multiple columns on the same table without suffering scaling
problems, especially at write time.
+
+While there are proposals to add some headline-grabbing features, such as JOIN
support to Apache Cassandra, some features confirm work that has already been
undertaken. For example, the experimental flag for Java 11 has been removed and
is now officially supported, while development to support Java 17 is in full
swing and Cassandra will take advantage of the rapidly evolving innovations in
Java garbage collection. As we’ve already seen in
https://jaxenter.com/apache-cassandra-java-174575 [...]
+
+The latest release of Apache Cassandra is 4.0.1, which was rapidly pushed out
to deal with a
https://issues.apache.org/jira/browse/CASSANDRA-16877[bug,window=_blank] in
Gossip on large clusters.
