I am writing to inform you that the following databases have been successfully patched as part of the scheduled maintenance:

• [Database Name/Target 1]
• [Database Name/Target 2]
• [Database Name/Target 3]
  (Include all patched databases as necessary.)

During the patching review, it was identified that several databases still contain application accounts operating with Oracle 10g compatibility. Patching these targets could result in potential authentication failures due to version incompatibilities. Therefore, to ensure uninterrupted operations, we have excluded these databases from the current patching cycle.

We recommend reviewing and updating the application accounts to a supported compatibility version at the earliest. Once the accounts are updated, we can include these targets in the next maintenance window.

 I have reviewed the list of databases scheduled for the upcoming patching activity and noticed that some targets include only a single node of a cluster in scope. For patching to be successful, it is essential to include the complete cluster (all nodes) in the scope.

Proceeding with the patching in the current state may result in failures or inconsistencies. Kindly review and update the list to ensure all nodes of the affected clusters are included in the scope.

Please let me know if you need further clarification or assistance in identifying the incomplete targets.

 Subject: Concern Regarding Inappropriate Behavior at the Team Gathering

Dear [Manager's Name],

I am writing to bring to your attention an incident that occurred during our recent team gathering, which I believe requires your consideration.

During the event, one of the attendees repeatedly used abusive language, including making offensive remarks about someone’s mother, all while others were having dinner. This behavior was completely inappropriate and unprovoked, creating an uncomfortable and negative environment.

What was even more troubling was the reaction of some senior members present at the table. While they were aware of the situation, their response included comments suggesting that such behavior is acceptable because the individual has been with UBS for 10 years. While experience and tenure are respected, I don’t believe such conduct aligns with the values of a professional and inclusive workplace.

It is important to address such incidents to ensure our work environment remains respectful and safe for everyone. Please let me know if you need further details about the incident or would like to discuss this matter further.

Thank you for your time and attention.

Best regards,

[Your Name]

 Subject: Concern Regarding Inappropriate Behavior at the Team Gathering

Dear [Manager's Name],

I hope this email finds you well. I am writing to bring to your attention an unfortunate incident that occurred during our recent team gathering, which I believe warrants your notice.

While most of the evening was enjoyable, there was a disturbing moment where one of the attendees began cursing repeatedly, including making inappropriate comments about someone’s mother. This behavior was completely unprovoked and occurred while others, including myself, were having dinner.

What was particularly disheartening was that senior team members were present at the table and were fully aware of the interaction. However, instead of addressing or diffusing the situation, some appeared to side with the individual engaging in this unacceptable behavior.

I want to emphasize that such abuses, especially personal ones directed towards family, are entirely intolerable and create an extremely negative and unsafe atmosphere. I believe it’s important to address this matter to maintain the respectful and professional environment we strive for.

Please let me know if you’d like further details about the incident or witnesses who were present. I trust you’ll take the necessary steps to ensure such behavior is not repeated in the future.

Thank you for your attention.

Best regards,

[Your Name]

 Subject: Update on Data Replication Issue

Dear [Application Owners],

We have raised a case with the vendor to further investigate and assist with the reported data replication issue. All relevant information and logs have been provided to their support engineer, and we are actively following up on this matter.

In the meantime, could you please confirm the following:

1. Were there any bulk data loads performed recently that might be related to this issue?

2. Was Replica2 the instance you were writing to? My understanding is that you were reading from Replica2, but I would like to double-check to ensure accuracy.

Your inputs will help us expedite the troubleshooting process. We will keep you updated as we receive further updates from the vendor.

Best regards,

 Description of the Issue:

We are experiencing a data replication latency issue in our PostgreSQL setup managed by Patroni. The issue was reported by the application team when querying a view on the replica node. The data was not initially visible on the replica but was accessible on the leader (primary). After a delay, the data became available on the replica.

The observed latency is a concern, especially for application functionalities dependent on near real-time data replication.

Setup Details:

• Environment: Patroni-managed PostgreSQL High Availability (HA) Cluster
• Replication Mode: Asynchronous
• Primary-Replica Configuration: 1 leader (primary) and 2 replicas
• Patroni Version: [Specify Version]
• PostgreSQL Version: [Specify Version]
• Replication Slots: Enabled/Disabled (specify)
• Network Setup: Nodes are within the same data center / across regions (specify).

Observations:

1. pg_last_xact_replay_timestamp:
   The timestamp on the replica node indicated it was lagging behind the leader.

   • The last replayed transaction timestamp was older than expected, even when active transactions were occurring on the primary.

2. Behavior:

   • Data committed on the leader was visible immediately.
   • A noticeable delay occurred before the data was available on the replica.
   • No significant load or downtime was observed during this period.

3. WAL Replication:

   • WAL logs appear to be streaming, but the application of WALs on the replica may be delayed.

4. System Logs:

   • No errors or warnings related to replication in PostgreSQL logs or Patroni logs during the observed delay.

Actions Taken So Far:

• Verified the status of replication using pg_stat_replication.
• Monitored resource utilization (CPU, memory, I/O) on replica nodes—found no significant bottlenecks.
• Checked network latency between the leader and replicas—no anomalies detected.
• Ensured that WAL archiving and replication settings align with recommended configurations.

Request for Assistance:

We would like assistance from the EDB team in investigating the following:

1. Possible causes of replication delays in this setup.
2. Guidance on advanced tuning for replication in Patroni with PostgreSQL to ensure minimal latency.
3. Suggestions for any additional diagnostic steps or logs to examine for identifying root causes.

Please let us know if you need further details about our environment or configurations.

Urgency Level: Medium / High (based on application needs)

Thank you for your assistance in resolving this issue.

 Dear [Application Team/Concerned Team],

Thank you for bringing the issue regarding the delayed availability of data on the PostgreSQL replica to our attention. We have thoroughly investigated the reported behavior and would like to share our findings and potential root cause analysis.

Issue Overview

• The application team reported that data from a specific view was not visible on the replica site, although it was present and accessible on the leader (primary) site.
• After some time, the data appeared on the replica, but the delay caused operational concerns.

Observations

1. pg_last_xact_replay_timestamp() Analysis:
   Upon checking, the value of pg_last_xact_replay_timestamp on the replica indicated a significant time lag. As per PostgreSQL documentation:

   • This timestamp reflects the last transaction replayed on the replica.
   • If there are no recent transactions on the primary, there is nothing to replay on the replica, which may cause this timestamp to appear older.

2. Replica Lag:
   While this behavior is expected during periods of low transactional activity, in this instance, the transaction was committed on the primary and available for querying, but it took noticeable time to replicate and reflect on the replica.

Potential Causes

Based on our analysis, the delay might be attributed to one or more of the following:

1. Network Latency:
   Replication relies on network communication between the primary and replica nodes. Any transient network issues could delay WAL (Write-Ahead Log) transfer to the replica.

2. Replica Processing Load:
   High resource utilization (e.g., CPU or I/O) on the replica server could slow down the replay of WALs, leading to visible delays in reflecting recent transactions.

3. Replication Slot Behavior:
   If replication slots are configured, any temporary backpressure in WAL streaming or applying could contribute to replication lag.

4. Idle Transactions:
   While the replica might appear "behind," it could be due to an idle period on the primary. However, since this delay coincided with an active transaction, it suggests there may have been a bottleneck in WAL application.

Next Steps and Recommendations

1. Immediate Mitigation:

   • Monitoring has been enhanced to capture replication lag (using metrics like pg_stat_replication.lag). Alerts will notify us if the lag exceeds acceptable thresholds.

2. Root Cause Analysis:

   • We are analyzing logs and performance metrics to identify any underlying network issues or resource bottlenecks.
   • WAL archiving and streaming settings will be reviewed to optimize replication performance.

3. Long-Term Actions:

   • Consider implementing synchronous replication for critical views/data if the application requires real-time consistency between leader and replica (with an understanding of potential impact on write performance).
   • Fine-tune replica server resource allocations to minimize processing delays.
