The classic scheduler has been the default for all versions of the Windows Hyper-V hypervisor since its inception, including Windows Server 2016 Hyper-V. The classic scheduler provides a fair share, preemptive round- robin scheduling model for guest virtual processors.
The core scheduler is used by default starting in Windows Server 2019. On Windows Server 2016, the core scheduler is optional and must be explicitly enabled by the Hyper-V host administrator, and the classic scheduler is the default.
Starting with Windows 10 version 1803, the root scheduler is used by default on client systems only, where the hypervisor may be enabled in support of virtualization-based security and WDAG workload isolation, and for proper operation of future systems with heterogeneous core architectures. This is the only supported hypervisor scheduler configuration for client systems. Administrators should not attempt to override the default hypervisor scheduler type on Windows 10 client systems.
Once the virtualization host's hypervisor is configured to use the core scheduler type, guest virtual machines may be configured to utilize SMT if desired. Exposing the fact that VPs are hyperthreaded to a guest virtual machine allows the scheduler in the guest operating system and workloads running in the VM to detect and utilize the SMT topology in their own work scheduling. On Windows Server 2016, guest SMT is not configured by default and must be explicitly enabled by the Hyper-V host administrator. Starting with Windows Server 2019, new VMs created on the host inherits the host's SMT topology by default. That is, a version 9.0 VM created on a host with 2 SMT threads per core would also see 2 SMT threads per core.
Windows Server 2016 Hyper-V uses the classic hypervisor scheduler model by default. The hypervisor can be optionally configured to use the core scheduler, to increase security by restricting guest VPs to run on corresponding physical SMT pairs, and to support the use of virtual machines with SMT scheduling for their guest VPs.
To help ensure Hyper-V hosts are deployed in the optimal security configuration, Windows Server 2019 Hyper-V now uses the core hypervisor scheduler model by default. The host administrator may optionally configure the host to use the legacy classic scheduler. Administrators should carefully read, understand and consider the impacts each scheduler type has on the security and performance of virtualization hosts prior to overriding the scheduler type default settings. See About Hyper-V hypervisor scheduler type selection for more information.
Within your mail configuration file, you will find a mailers configuration array. This array contains a sample configuration entry for each of the major mail drivers / transports supported by Laravel, while the default configuration value determines which mailer will be used by default when your application needs to send an email message.
Next, set the default option in your application's config/mail.php configuration file to mailgun. After configuring your application's default mailer, verify that your config/services.php configuration file contains the following options:
Next, set the default option in your application's config/mail.php configuration file to postmark. After configuring your application's default mailer, verify that your config/services.php configuration file contains the following options:
Once your failover mailer has been defined, you should set this mailer as the default mailer used by your application by specifying its name as the value of the default configuration key within your application's mail configuration file:
The table component allows you to transform a Markdown table into an HTML table. The component accepts the Markdown table as its content. Table column alignment is supported using the default Markdown table alignment syntax:
After exporting the components, the resources/views/vendor/mail/html/themes directory will contain a default.css file. You may customize the CSS in this file and your styles will automatically be converted to inline CSS styles within the HTML representations of your Markdown mail messages.
By default, Laravel will send email using the mailer configured as the default mailer in your application's mail configuration file. However, you may use the mailer method to send a message using a specific mailer configuration:
By default, the MIME type of the body parameter in anEmailMessage is "text/plain". It is goodpractice to leave this alone, because it guarantees that any recipient will beable to read the email, regardless of their mail client. However, if you areconfident that your recipients can handle an alternative content type, you canuse the content_subtype attribute on theEmailMessage class to change the main content type.The major type will always be "text", but you can change thesubtype. For example:
Django ships with several email sending backends. With the exception of theSMTP backend (which is the default), these backends are only useful duringtesting and development. If you have special email sending requirements, youcan write your own email backend.
Instead of sending out real emails the console backend just writes theemails that would be sent to the standard output. By default, the consolebackend writes to stdout. You can use a different stream-like object byproviding the stream keyword argument when constructing the connection.
The protagonist of Persona 5, canonically known as Ren Amamiya (after having been used in several media, before eventually being confirmed due to its use as his default name in the 2022 re-release of Persona 5 Royal), is a second-year transfer student at Shujin Academy, being placed there to continue his academics due to his ongoing probation resulting from being falsely framed for assault.[2][3][4]
His default outfit is his winter school uniform, which consists of a red-buttoned black blazer with Shujin's emblem on the pocket, a white turtleneck shirt with chevron detailing on the collar and slim red pants with a plaid pattern. It is shown in Episode 5 of Persona 5 The Animation that he wears black suspenders under his blazer. His uniform is worn with black, laced dress boots. During the summer, he wears the school regulation polo shirt, albeit untucked and sans the suspenders.
These sample configuration files, included with Kafka, use the default local cluster configuration you started earlier and create two connectors: the first is a source connector that reads lines from an input file and produces each to a Kafka topic and the second is a sink connector that reads messages from a Kafka topic and produces each as a line in an output file.
NOTE: any prefixed ACLs added to a cluster, even after the cluster is fully upgraded, will be ignored should the cluster be downgraded again. Notable changes in 2.0.0 KIP-186 increases the default offset retention time from 1 day to 7 days. This makes it less likely to "lose" offsets in an application that commits infrequently. It also increases the active set of offsets and therefore can increase memory usage on the broker. Note that the console consumer currently enables offset commit by default and can be the source of a large number of offsets which this change will now preserve for 7 days instead of 1. You can preserve the existing behavior by setting the broker config offsets.retention.minutes to 1440.
Support for Java 7 has been dropped, Java 8 is now the minimum version required.
The default value for ssl.endpoint.identification.algorithm was changed to https, which performs hostname verification (man-in-the-middle attacks are possible otherwise). Set ssl.endpoint.identification.algorithm to an empty string to restore the previous behaviour.
KAFKA-5674 extends the lower interval of max.connections.per.ip minimum to zero and therefore allows IP-based filtering of inbound connections.
KIP-272 added API version tag to the metric kafka.network:type=RequestMetrics,name=RequestsPerSec,request=.... This metric now becomes kafka.network:type=RequestMetrics,name=RequestsPerSec,request=FetchFollower,version=3. This will impact JMX monitoring tools that do not automatically aggregate. To get the total count for a specific request type, the tool needs to be updated to aggregate across different versions.
KIP-225 changed the metric "records.lag" to use tags for topic and partition. The original version with the name format "topic-partition.records-lag" has been removed.
The Scala consumers, which have been deprecated since 0.11.0.0, have been removed. The Java consumer has been the recommended option since 0.10.0.0. Note that the Scala consumers in 1.1.0 (and older) will continue to work even if the brokers are upgraded to 2.0.0.
The Scala producers, which have been deprecated since 0.10.0.0, have been removed. The Java producer has been the recommended option since 0.9.0.0. Note that the behaviour of the default partitioner in the Java producer differs from the default partitioner in the Scala producers. Users migrating should consider configuring a custom partitioner that retains the previous behaviour. Note that the Scala producers in 1.1.0 (and older) will continue to work even if the brokers are upgraded to 2.0.0.
MirrorMaker and ConsoleConsumer no longer support the Scala consumer, they always use the Java consumer.
The ConsoleProducer no longer supports the Scala producer, it always uses the Java producer.
A number of deprecated tools that rely on the Scala clients have been removed: ReplayLogProducer, SimpleConsumerPerformance, SimpleConsumerShell, ExportZkOffsets, ImportZkOffsets, UpdateOffsetsInZK, VerifyConsumerRebalance.
The deprecated kafka.tools.ProducerPerformance has been removed, please use org.apache.kafka.tools.ProducerPerformance.
New Kafka Streams configuration parameter upgrade.from added that allows rolling bounce upgrade from older version.
KIP-284 changed the retention time for Kafka Streams repartition topics by setting its default value to Long.MAX_VALUE.
Updated ProcessorStateManager APIs in Kafka Streams for registering state stores to the processor topology. For more details please read the Streams Upgrade Guide.
In earlier releases, Connect's worker configuration required the internal.key.converter and internal.value.converter properties. In 2.0, these are no longer required and default to the JSON converter. You may safely remove these properties from your Connect standalone and distributed worker configurations: internal.key.converter=org.apache.kafka.connect.json.JsonConverter internal.key.converter.schemas.enable=false internal.value.converter=org.apache.kafka.connect.json.JsonConverter internal.value.converter.schemas.enable=false
KIP-266 adds a new consumer configuration default.api.timeout.ms to specify the default timeout to use for KafkaConsumer APIs that could block. The KIP also adds overloads for such blocking APIs to support specifying a specific timeout to use for each of them instead of using the default timeout set by default.api.timeout.ms. In particular, a new poll(Duration) API has been added which does not block for dynamic partition assignment. The old poll(long) API has been deprecated and will be removed in a future version. Overloads have also been added for other KafkaConsumer methods like partitionsFor, listTopics, offsetsForTimes, beginningOffsets, endOffsets and close that take in a Duration.
Also as part of KIP-266, the default value of request.timeout.ms has been changed to 30 seconds. The previous value was a little higher than 5 minutes to account for maximum time that a rebalance would take. Now we treat the JoinGroup request in the rebalance as a special case and use a value derived from max.poll.interval.ms for the request timeout. All other request types use the timeout defined by request.timeout.ms
The internal method kafka.admin.AdminClient.deleteRecordsBefore has been removed. Users are encouraged to migrate to org.apache.kafka.clients.admin.AdminClient.deleteRecords.
The AclCommand tool --producer convenience option uses the KIP-277 finer grained ACL on the given topic.
KIP-176 removes the --new-consumer option for all consumer based tools. This option is redundant since the new consumer is automatically used if --bootstrap-server is defined.
KIP-290 adds the ability to define ACLs on prefixed resources, e.g. any topic starting with 'foo'.
KIP-283 improves message down-conversion handling on Kafka broker, which has typically been a memory-intensive operation. The KIP adds a mechanism by which the operation becomes less memory intensive by down-converting chunks of partition data at a time which helps put an upper bound on memory consumption. With this improvement, there is a change in FetchResponse protocol behavior where the broker could send an oversized message batch towards the end of the response with an invalid offset. Such oversized messages must be ignored by consumer clients, as is done by KafkaConsumer. KIP-283 also adds new topic and broker configurations message.downconversion.enable and log.message.downconversion.enable respectively to control whether down-conversion is enabled. When disabled, broker does not perform any down-conversion and instead sends an UNSUPPORTED_VERSION error to the client. 2ff7e9595c
