The binary log and relay log in Replication to a certain extend have the structure.

There are few scenarios that we may consider using the Binary Log to recover the data. To speed up replication on start up https: The recovery channel is named as 'channel2' 4. The binary log prefix is mysqllog. Stop the slave on channel1 stop slave for channel 'channel1' 2.

Copy the 'channel2' relay log files to Slave's datadir 6. Create the channel2 channel on Slave and Start Slave for channel 'channel2'. After recovery, Stop the channel 'channel2' and clean up. Today, we are announcing a suite of open source Linux kernel components and related tools that address critical fleet management issues.

These include resource control, resource utilization, workload isolation, load balancing, measuring, monitoring, and much more. BPF BPF is a highly flexible, efficient code execution engine in the Linux kernel that allows bytecode to run at various hook points, enabling safe and easy modifications of kernel behaviors with custom code.

At Facebook, ensuring fast, reliable access for our users is a top priority.

To achieve this goal, our infrastructure engineers have developed traffic optimization systems in which BPF plays a prominent role. One such case is Katrana software-based load-balancing solution with a completely reengineered forwarding plane that takes advantage of the BPF virtual machine.

It is a copy-on-write CoW filesystem focused on advanced feature implementation, fault tolerance, repair, and easy administration.

Btrfs is designed to address and manage large storage subsystems and supports features such as snapshots, online defragmentation, pooling, and integrated multiple device support.

Netconsd Netconsd is a UDP-based netconsole daemon that provides lightweight transport for Linux netconsole messages. It receives and processes log data from the Linux kernel and serves it up as structured data in a way that helps production engineers rapidly identify issues in the fleet.

At Facebook, netconsd provides vital data center statistics. It logs data continuously from millions of hosts and allows engineers to extract meaningful signals from the voluminous log data noise generated in the kernel, helping on-call production engineers rapidly identify and diagnose misbehaving services.

Cgroup2 Cgroup2 is the next-gen Linux kernel mechanism for grouping and structuring workloads, and controlling the amount of system resources assigned to each group. It also allows you to isolate workloads and prioritize and configure the distribution of resources for each one.

The fbtax project demonstrated the possibility of comprehensive resource isolation while using operating system features such as memory management and file systems, opening the door to increased fleet efficiency by making workload stacking straightforward and safe.

Check out the fbtax2 case study in the cgroup2 documentation for details. PSI Pressure Stall Information PSI provides for the first time a canonical way to quantify resource shortages with new pressure metrics for three major resources: PSI stats provide early warning of impending resource shortages, enabling more proactive, granular, and nuanced responses.

We use PSI at Facebook in conjunction with cgroup2 to provide per-cgroup insight into resource use and misuse of a wide variety of different workloads, enabling increased utilization and reliability in situations in which resources are insufficient. Visual showing how the various components and tools work together.

Oomd Oomd is a userspace OOM out-of-memory process killer that acts with greater awareness of the context and priority of processes running on a system. It allows you to configure responses to OOM conditions, such as pausing or killing nonessentials, reallocating memory in the system, or other actions.

OOM killing traditionally happens inside the kernel. If a system runs out of physical memory, the Linux kernel is forced to OOM-kill one or more processes. On top of this behavior, configuring policy is complicated and inflexible. Oomd solves these problems in userspace by taking corrective action before an OOM occurs in kernel.

A flexible plugin system that supports custom detection logic configures these actions. Oomd allows you to write custom protection rules for each workload. Limitless possibilities The use cases described here are just the beginning.After you have loaded the mysqldump files to create the databases on the MySQL instance running external to Amazon RDS, start replication from the source MySQL DB instance to export all source changes that have occurred after you stopped replication from the Amazon RDS Read Replica.

This blog post discusses a new TokuDB and PerconaFT database file management feature in two Percona Server releases. By now you have hopefully read through Peter’s post and my two prior posts on the TokuDB/PerconaFT file set.

“MySQL in the Network” — Here you learn how to scale out MySQL using such techniques as replication. Chapter 8. You should also be familiar with basic system management — editing files. and perhaps PHP.
