Data-bearing members face a higher risk of encountering issues caused by rollbacks, compared to others who utilize different storage methods. For example, memory-resident databases without persistent disks, such as Redis cluster setups or Apache Spark installations, rely on stand-alone machines.

This type of backup is suitable for large, important databases that need to be recovered quickly when problems occur. Physical backups are the backups that consist of raw copies of the directories and files that store database contents. Copyright (c) 2016, 2023, Oracle and/or its affiliates. Press ^C to stop.

In a recent tip , I described a scenario where a SQL Server 2016 instance seemed to be struggling with checkpoint times. I was a bit perplexed by this issue, since the system was certainly no slouch — plenty of cores, 3TB of memory, and XtremIO storage. Change the Target Recovery Time of a Database.

What if we use ClickHouse (which is a columnar analytical database) as our main datastore? Well, typically, an analytical database is not a replacement for a transactional or key/value datastore. Although such databases can be very efficient with counts and averages, some queries will be slow or simply non existent. Processed 4.15
