+<h2 id="about">About</h2>
+
+<p>Apache Accumulo 4.0.0 is a non-LTM major version release that contains
+a large number of internal changes that allow a lot of flexibility in
+the way that Accumulo is deployed with a small number of API changes.
+A high level overview of some of the changes are described in <a
href="/blog/2024/10/07/accumulo4-preview.html">this</a>
+blog post.</p>
+
+<h2 id="notable-changes">Notable Changes</h2>
+
+<ul>
+ <li>
+ <p>Accumulo 4.0.0 requires Java 21 for compilation and Java 17 for
runtime.</p>
+ </li>
+ <li>
+ <p>Bulk Import V1 has been removed. Users will need to migrate to Bulk
Import V2.</p>
+ </li>
+ <li>
+ <p>Tablet merges no longer require a chop compaction on the participating
files. To facilitate
+this the file entry in the tablet metadata now includes the range for the
tablet data in
+the file.</p>
+ </li>
+ <li>
+ <p>FaTE locks include tablet ranges where possible to allow for concurrent
FaTE operations
+on non-overlapping tablet ranges.</p>
+ </li>
+ <li>
+ <p>The CompactionCoordinator process no longer exists, its functionality
was moved into the Manager.</p>
+ </li>
+ <li>
+ <p>Non-system tablets will be optionally hosted by default. Operations
requiring a tablet to be
+hosted (live ingest and immediate consistency scans) will instruct the Manager
to temporarily
+assign the Tablet. Users can change the default hosting semantics for Tablets
when creating
+the table, using the TableOperations API, or the appropriate command in the
Shell. Tablets
+that are temporarily assigned are unloaded according to the logic in the
OnDemandTabletUnloader
+plugin being used, specified by the property
‘tserver.ondemand.tablet.unloader’. The default
+implementation will unload tablets that have not been used in 10 minutes,
which can be changed
+by the property ‘tserver.ondemand.tablet.unloader.interval’.</p>
+ </li>
+ <li>
+ <p>Considering TabletServers optionally host Tablets, all Tablet
management functions (e.g. merge,
+split, compaction initiation, bulk import, etc.) have been moved into the
Manager. TabletServers no longer
+perform major compactions making Compactor processes mandatory (ScanServers
remain an optional
+feature).</p>
+ </li>
+ <li>
+ <p>Tablets in a table can now be automatically merged. There is a manager
property to control the
+interval at which tablets are checked and a table property to control the
threshold for an
+automatic merge. Tablet mergeability can be specified at table creation time
or using
+<code class="language-plaintext
highlighter-rouge">TableOperations.putSplits</code>. The upgrade process sets
the tablet mergeability to never for
+all existing tablets to preserve any user created split points. Tablet
mergeability can be
+set when adding new splits and will be set to always when the split is created
by the system
+based on user settings. See <a
href="/docs/4.x/administration/merging">merging</a> for more information.</p>
+ </li>
+ <li>
+ <p>Split and Merge operations, which are now just metadata operations, can
be much faster for tablets
+that are not hosted. For tablets that are hosted in a TabletServer, they are
temporarily unloaded
+before the operation executes.</p>
+ </li>
+ <li>
+ <p>Multiple active Manager processes are supported. One active Manager is
considered the “primary”
+Manager and the others are considered “assistant” Managers. Clients will
connect to the primary
+Manager for Thrift operations requiring the Manager. If the primary Manager
process dies then one
+of the assistant Managers will become the Primary. The assistant Managers
participate in
+processing FaTE transactions, but not tablet management or coordinating major
compactions.</p>
+ </li>
+ <li>
+ <p>New table property <code class="language-plaintext
highlighter-rouge">table.compaction.minor.age</code> will cause a minor
compaction to be
+initiated when the oldest key-value in a Tablets’ in-memory-map exceeds the
value. This could
+be useful when using Scan Servers in conjunction with the Tablet Metadata
expiration property.</p>
+ </li>
+ <li>
+ <p>The HostRegexTableLoadBalancer has been deprecated. Similar
functionality can be achieved using
+the TableLoadBalancer and setting the property <code class="language-plaintext
highlighter-rouge">table.custom.assignment.group</code> on a table
+that references a set of Tablet Servers using the same resource group name.</p>
+ </li>
+ <li>
+ <p>The Monitor has been re-worked to mostly use the metrics emitted by the
various server processes.
+While the Monitor server does make some RPC calls, metrics will need to be
enabled using the
+property <code class="language-plaintext
highlighter-rouge">general.micrometer.enabled</code> on all server processes
for the Monitor to work properly.
+Endpoints for retrieving the underlying data from the Monitor server in XML or
JSON format have
+been removed. Users are encouraged to set up their own metric collection
system for gathering
+and visualizing metric data.</p>
+ </li>
+ <li>
+ <p>Log recovery work may now be performed in Compactor, Scan Server, and
Tablet Server processes.</p>
+ </li>
+ <li>
+ <p>User FaTE transactions are now stored in a table in the system
namespace. System FaTE transactions
+remain stored in ZooKeeper.</p>
+ </li>
+ <li>
+ <p>Scan Server file references have been moved out of the metadata table
and into their own table
+in the system namespace.</p>
+ </li>
+ <li>
+ <p>A Resource Group configuration layer has been added that allows the
user to override system-level
+properties for resource group processes.</p>
+ </li>
+ <li>
+ <p>Table configuration properties are now only allowed in the Namespace
and Table configuration layers.</p>
+ </li>
+ <li>
+ <p>The command line utilities have been updated. Run <code
class="language-plaintext highlighter-rouge">accumulo --help</code> to see the
changes. A bash
+completion script can be generated using the command <code
class="language-plaintext highlighter-rouge">accumulo conf
create-autocomplete-script</code>.</p>
+ </li>
+ <li>
+ <p>The number of threads used to process FaTE transactions can be
configured by FaTE transaction type
+for both user and system FaTE transactions.</p>
+ </li>
+</ul>
