Understanding transaction visibility in PostgreSQL clusters with read replicas

On April 29, 2025, Jepsen released a report on transaction visibility behavior in Amazon RDS for PostgreSQL and its Multi-AZ clusters, which has been acknowledged since at least 2013. The report identifies a Long Fork anomaly affecting the visibility order of transactions between primary and replica nodes in cluster configurations, which does not lead to data loss or corruption and is absent in Single-AZ deployments. This anomaly allows two readers to see transactions in different sequences, breaching Snapshot Isolation. It affects all isolation levels in community PostgreSQL and can also occur in self-managed deployments. The issue has been discussed extensively in the PostgreSQL community, and potential solutions, including synchronizing visibility with commit order using Commit Sequence Numbers, have been proposed. AWS has established the PostgreSQL Contributors Team to address this anomaly and enhance PostgreSQL's capabilities.

The summary shall NOT include a title, introduction and conclusion. Text: Microsoft has made a significant announcement regarding the future of hotpatching for Windows Server 2025, a feature that allows administrators to apply security updates without the need for system restarts. As the company prepares for the general availability of this service, it will transition to a paid subscription model starting July 1, 2025. Subscription Details and Preview Phase In a proactive move, Microsoft is encouraging administrators to take advantage of the free preview of hotpatching before it becomes a subscription-based service. This opportunity will remain available until June 30, after which those currently testing the service will be automatically subscribed unless they opt out. “Hotpatching for Windows Server 2025, made available in preview in 2024, will become generally available as a subscription service on July 1st, 2025. With hotpatching, we are taking what was previously an Azure-only capability and now making it available to Windows Server machines outside of Azure through Azure Arc,” Microsoft stated. Upon the subscription launch, hotpatching will be priced at .50 USD per CPU core per month. To utilize this feature in multi-cloud environments or on-premises, users will need both a Hotpatch service subscription and an Azure Arc-connected server running Windows Server 2025 Standard or Datacenter. How to Enable Hotpatching Enabling hotpatching on your server is a straightforward process. First, connect your server to Azure Arc by following the specified steps. Next, navigate to Azure Update Manager within the Azure Portal, select your Azure Arc-enabled server, and check the hotpatching option as outlined in the provided documentation.

Users must operate on Windows Server 2025 Standard or Datacenter, connected to Azure Arc, to access these updates. Starting July 1, 2025, there will be a charge of [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: In the realm of operating systems, security updates are paramount, especially when they pertain to software utilized by billions globally. However, Microsoft has recently found itself in a challenging spotlight following a controversial Windows security patch that inadvertently introduced a mysterious folder, sparking a wave of confusion and concern among users. Social media commentators hastily advised users to delete this folder, only for Microsoft to counter with a warning that such actions could leave systems vulnerable to attacks. This incident has now unveiled a broader issue within the Windows security update framework, particularly surrounding the introduction of a subscription model for no-reboot security “hotpatch” updates. What Is Windows Hotpatching, And Who Needs To Pay The .50 A Month Fee? As previously reported, Microsoft is advancing towards a system where hotpatching will eliminate the need for users to reboot their Windows systems after a security update. This innovative feature allows security fixes to be downloaded and installed seamlessly in the background, integrating directly into the in-memory code of processes that are already running. Initially, this functionality is set to be available for a specific segment of users: those operating Windows 11 Enterprise, version 24H2, on x64 (AMD/Intel) CPU devices managed through Microsoft Intune. Recent confirmations from Janine Patrick, Windows Server product marketing manager, and Artem Pronichkin, a senior program manager at Microsoft, indicate that the hotpatching system for Windows Server 2025, which has been in preview since 2024, will transition to a subscription-only model starting July 1. To utilize the no-reboot hotpatch security updates, users must operate on “Windows Server 2025 Standard or Datacenter,” with an essential requirement of being connected to Azure Arc. The noteworthy and contentious aspect of this announcement is the introduction of a subscription fee for the Hotpatch service.

Microsoft to Launch Paid Hotpatching for Windows Server 2025

Microsoft will launch a subscription-based hotpatching service for Windows Server 2025 on July 1, 2025, priced at [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Microsoft is set to transform the landscape of enterprise updates with the upcoming launch of its subscription-based hotpatching service for Windows Server 2025. This innovative approach marks a significant shift in how updates will be managed for businesses operating Windows Server outside of Azure. Beginning July 1, 2025, hotpatching will transition from a complimentary preview to a paid subscription model, priced at .50 per CPU core per month. This change extends a capability that was previously exclusive to Azure users, now making it accessible for on-premises servers and hybrid environments through Azure Arc integration. What Is Hotpatching? Hotpatching is a cutting-edge technology that enables the installation of security and critical updates without necessitating a system reboot. Instead of interrupting services or rebooting servers, hotpatching directly updates the in-memory code of running processes. This advancement brings Windows server deployments in line with similar technologies that Linux administrators have enjoyed for years, such as kpatch and ksplice. By allowing updates without reboots, organizations can significantly reduce disruptions while enhancing their security posture. How Does Hotpatching Work? The hotpatching mechanism follows a structured update cycle: Baseline months: In January, April, July, and October, a full cumulative update will be released, requiring a reboot to establish a new baseline. Hotpatch months: In the two months following each baseline month, critical patches will be deployed via hotpatches without requiring any server reboots. This means that servers will only need to reboot approximately four times a year, rather than monthly. On rare occasions, Microsoft may issue a critical security update that requires a reboot even during a hotpatch month, but the aim remains clear: to provide up to eight rebootless hotpatches annually. Why Is Microsoft Moving to a Paid Model? While hotpatching was available at no additional cost during its preview phase, Microsoft is now positioning it as a premium feature for customers seeking maximum uptime, operational simplicity, and rapid security response. According to the Windows Server team at Microsoft, the value of hotpatching encompasses: Reduced Downtime: Maintain operations without the need for scheduling late-night or weekend reboot windows. Faster Updates: Smaller patches facilitate quicker deployments. Enhanced Security: Address vulnerabilities swiftly without delays associated with reboot coordination. Operational Efficiency: Streamlined change management and patch orchestration. Internal teams at Microsoft, including the Xbox division, have already experienced notable efficiency improvements with hotpatching, completing tasks that previously took weeks in just days. Subscription Details Feature Details Launch Date July 1, 2025 Price .50 USD per CPU core per month Editions Supported Windows Server 2025 Standard and Datacenter Deployment Requirement Must be connected to Azure Arc Included with Azure Editions Datacenter: Azure Edition (no extra charge) Patch Frequency 8 hotpatches/year + 4 reboot-required baseline patches Organizations currently utilizing the free preview must either opt out before June 30, 2025, or they will be automatically transitioned into the paid subscription starting in July. While hotpatching offers powerful capabilities, it does not entirely eliminate the need for traditional updates. Certain updates will still necessitate a reboot, including: Major non-security updates. .NET Framework patches. Driver and firmware updates. Emergency out-of-band security patches. As such, administrators should still anticipate occasional downtime, albeit significantly reduced.
