We can disable saving of the history either via command-line parameter --disable-history, or by setting disabled = True in the history section of the cqlshrc. Both options will read existing history, and just won't save new commands.
Update help and docs for cqlsh history.
Add startup info logline whenr history logging is enabled.
Add a fix for cqlshrc file path not correctly expanding.
Includes the Backport of
Allows users to change cqlsh history location using env variable

G1 can rely on `-XX:G1NewSizePercent=50` to always floor the young generation's size to 50% of the heap. (In production this can be raised to 66% for optimal performance.)
Fixing the young generation size with `-Xmn` is only applicable to CMS, so move it to the appropriate section.
When using G1, we can automatically set `-XX:ParallelGCThreads` and `-XX:ConcGCThreads` to the number of system cpu cores.
The auto-generated heap size is now half the server's physical RAM, capped at 16G for CMS and 31G for G1.
Increase MaxTenuringThreshold from 1 to 2, as evidence has shown it has no cost (over values of zero or one), but can have significant benefits in keeping objects in the young generation. While, values above 2 don't have any noticeable benefit.
Always set CASSANDRA_HEAPDUMP_DIR, default it to $CASSANDRA_LOG_DIR, to avoid hprof filling up unexpected disk volumes. Assumption here is that the logs directory is large enough to handle these dumps, and/or operators are monitoring these directories more than other randon/unknown directories.

The presence of an extra space the `:` in `key: value` pairs
makes the default `conf/cassandra.yaml` file included in
this repository unparseable and non-functional for some downstream tooling.
patch by Daniel Lenski; reviewed by Stefan Miklosovic, Brandon Williams for CASSANDRA-20359
configuration section for native_transport_max_auth_threads with default value of 4 was added to cassandra.yaml
as part of this merge-up as this section was forgotten to be added in the original patch of CASSANDRA-17812
This backport differs from CASSANDRA-17812 in such a way that by default the number
of auth request threads is set to 0. That will route all requests to request executor as before this change.
The patch in 5.0 and later sets the default number of auth request threads to 4.

Batchlog endpoint strategy was previously only random placements on other racks. Options now are random_remote, prefer_local, dynamic_remote, and dynamic.
patch by Shayne Hunsaker; reviewed by Mick Semb Wever, Brandon Williams for CASSANDRA-18120
Uses ParameterizedClass for IAuthorizer, INetworkAuthorizer, and
IRoleManager implementations enabling those to be configurable from
parameters specified directly in cassandra.yaml.
Opportunistically makes consistent the initialization and setting of
all auth-related implementations and removes code duplication.
Notes:
* IInternodeAuthenticator implementations are expected to be set as
default directly in DatabaseDescriptor instead of done via
AuthConfig.applyAuth(). This is assumed in tests and client logic.
For instance ReconnectableSnitchHelperTest fetches this authenticator
before calling daemonInitialize(). Also, BulkLoader fetches this
directly when creating an outbound connection.
* Changing this behavior in BulkLoader causes a cascade of changes.
First, one would need to add AuthConfig.applyAuth() directly in
clientInitialize() and then would need to enable all the additional
classes that this change causes. Long term this might be justified
as if we're depending on the auth logic to be properly set. However,
in the context of this change it was decided to postpone further
changes.
* Standardize auth-related configurations by using a short-form with
the class name instead of the full qualified class name containing
the package name.

not adding this open triggered warnings in tools like auditlogviewer when on Java 11
patch by Stefan Miklosovic; reviewed by Brad Schoening for CASSANDRA-19780
This patch adds a new configuration file, cassandra_latest.yaml, which changes
some of the settings to use new features we usually recommend to users,
including:
- Big Trie-Indexed SSTables
- Trie memtables
- Unified Compaction Strategy
- Storage Attached Index
- Off-heap objects memtables
- Direct-write commit log
- No storage compatibility
These changes are applied in new test targets for unit, in-jvm and python dtests that are
run pre-commit. When changes are made to the new config file, python dtest will use it
directly, but unit and in-jvm dtests require updates, respectively, to latest_diff.yaml
and InstanceConfig.java.

/bin/sh (our shebang in bin/cassandra) does not recognize the
`if` construct which is available in /bin/bash only hence if
MX4J_ADDRESS or MX4J_PORT was not commented out, the script would
fail to execute it.
