When SSL is enabled, the DN configures DCF as TLS 1.2 by default. -- DCF supports five TLS 1.3 cipher suites: TLS13-AES-256-GCM-SHA384, TLS13-CHACHA20-POLY1305-SHA256, TLS13-AES-128-GCM-SHA256, TLS13-AES-128-CCM-8-SHA256 and TLS13-AES-128-CCM-SHA256. -- DCF supports passive nodes, which do not participate in leader election and only synchronize and replay logs. When this type of nodes is heavily loaded during log synchronization, flow control is performed. -- DCF supports logger nodes, which participate in leader election and voting. However, the logger nodes only replicate DCF logs. Xlogs are not replicated and redo is not performed. -- DCF supports online switchover between follower and passive nodes. That is, without interrupting services, a node can switch over between the follower and passive roles. -- DCF supports forcible startup of the minority of DNs. In case that the majority of database instances are faulty, a minority of standby DNs are selected and forcibly promoted to primary, and other normal standby DNs replicate logs from the primary DNs. -- DCF supports automatic leader election. When the original primary DN is faulty, a new primary DN is automatically selected from the remaining standby DNs on the premise that data consistency is ensured. -- DCF supports the policy-based majority capability. Based on the configured AZ, DCF ensures that at least one node in the AZ synchronizes replication logs. - -## Enhancements - -None. - -## Constraints - -To use this function, you need to enable DCF during installation and deployment. In DCF mode, the majority election is used. During the installation, if the number of faulty nodes and build nodes reaches the majority, the cluster installation will fail. For example, when one primary node and two standby nodes are installed, one node fails to be installed due to insufficient memory, but the other two nodes can be started normally. A standby node will be built again. In this case, the number of build nodes and faulty nodes is 2, which is the majority, and the cluster installation will fail. During the installation, check whether the memory and disk resources are sufficient. - -If the policy-based majority parameter is configured for an AZ and all nodes in the AZ are faulty, you need to remove the AZ configuration from the policy-based majority configuration when performing build operations on the nodes. - -The manual mode is used to set the cluster-level working mode. In this mode, the logger or passive role is not supported. - -## Dependencies - -None. - -## Related Pages - -[DCF](../../reference-guide/sql-reference/sql-reference-dcf.md) \ No newline at end of file +--- +title: DCF +summary: DCF +author: Guo Huan +date: 2022-05-10 +--- + +# DCF + +## Availability + +This feature is available since MogDB 2.0.0. + +## Introduction + +Distributed consensus framework (DCF) implements data synchronization based on the Paxos algorithm.

When SSL is enabled, the DN configures DCF as TLS 1.2 by default. +- DCF supports five TLS 1.3 cipher suites: TLS13-AES-256-GCM-SHA384, TLS13-CHACHA20-POLY1305-SHA256, TLS13-AES-128-GCM-SHA256, TLS13-AES-128-CCM-8-SHA256 and TLS13-AES-128-CCM-SHA256. +- DCF supports passive nodes, which do not participate in leader election and only synchronize and replay logs. When this type of nodes is heavily loaded during log synchronization, flow control is performed. +- DCF supports logger nodes, which participate in leader election and voting. However, the logger nodes only replicate DCF logs. Xlogs are not replicated and redo is not performed. +- DCF supports online switchover between follower and passive nodes. That is, without interrupting services, a node can switch over between the follower and passive roles. +- DCF supports forcible startup of the minority of DNs. In case that the majority of database instances are faulty, a minority of standby DNs are selected and forcibly promoted to primary, and other normal standby DNs replicate logs from the primary DNs. +- DCF supports automatic leader election. When the original primary DN is faulty, a new primary DN is automatically selected from the remaining standby DNs on the premise that data consistency is ensured. +- DCF supports the policy-based majority capability. Based on the configured AZ, DCF ensures that at least one node in the AZ synchronizes replication logs. + +## Enhancements + +None. + +## Constraints + +To use this function, you need to enable DCF during installation and deployment. In DCF mode, the majority election is used. During the installation, if the number of faulty nodes and build nodes reaches the majority, the cluster installation will fail. For example, when one primary node and two standby nodes are installed, one node fails to be installed due to insufficient memory, but the other two nodes can be started normally. A standby node will be built again. In this case, the number of build nodes and faulty nodes is 2, which is the majority, and the cluster installation will fail. During the installation, check whether the memory and disk resources are sufficient. + +If the policy-based majority parameter is configured for an AZ and all nodes in the AZ are faulty, you need to remove the AZ configuration from the policy-based majority configuration when performing build operations on the nodes. + +The manual mode is used to set the cluster-level working mode.

Based on the service scenarios, and requirements for high performance and ecosystem, DCF has made many function extensions and performance optimization to enrich the functions compared with the basic Multi-Paxos protocol, and the performance is significantly improved in multiple deployment scenarios. It mainly includes a leader election module, a log replication module, a metadata module, and a cluster management module. - -- **Storage module:** - - For specific service scenarios and ultimate performance, the DCF extracts a set of public interfaces for log storage and implements a default high-performance storage module. For specific scenarios or users who have ultimate performance and cost requirements, you can connect the existing storage system to the log storage interface of DCF to meet specific requirements. This is one of the advantages of DCF as an independent third-party library. - -- **Communication module:** - - The communication module is implemented based on the Message Exchange Component (MEC) and provides the communication capability between DCF instances and the asynchronous event processing framework. The main features are as follows: multiple extensible communication protocols, unicast, broadcast, and loopback sending interfaces, asynchronous message processing framework, multi-channel mechanism, multi-priority queue, compression, and batch sending. - -- **Service layer:** - - The service layer is the basis for running the entire DCF and provides various basic services required for program running. For example, lock, asynchronous task scheduling, thread pool service, and timer. - -## Features - -- **Nodes can be added and deleted online, and the leader role can be handed over online.** - - Based on the standard Multi-Paxos, the DCF supports online node addition and deletion, and leader handover. This is more suitable for building a development ecosystem in a wide range of service scenarios. - -- **Priority-based leader election and policy-based majority are supported.** - - - **Policy-based majority**: In the classic Paxos theory, data can be submitted after the majority reaches a consensus. However, the majority is not specific and it cannot be guaranteed that one or some nodes can obtain complete data. In actual applications, the nodes that are geographically close to each other have strongly consistent data, but the nodes that are geographically far away from each other are always in a non-strongly consistent state. These nodes cannot be activated as the primary node for city-level disaster recovery. The policy-based majority mechanism enables users to dynamically configure one or more nodes to be strongly consistent and can be activated as the primary node immediately for disaster recovery. - - **Priority-based leader election**: You can specify the priority of each node. The DCF elects a leader node strictly according to the specified priority. The node with a lower priority is activated only when all the nodes with a higher priority are unavailable. - -- **Diversified node roles are provided.** - - In addition to typical roles such as Leader, Follower, and Candidate, the DCF also supports customized roles, for example, the Passive role (with logs, with data, without the right to be elected, and not participating in the majority voting) and the Log role (with logs, without data, without the right to be elected, and participating in the mkajority voting). With these node roles, DCF supports synchronous and hybrid (synchronous/asynchronous) multi-cluster deployment. - -- **Batch & Pipeline** - - - **Batch**: The DCF supports multi-level batch operations, including: - - - Combine multiple logs into a single message for sending. - - Combine multiple logs for writing to the disk. - - Combine multiple logs for replication. - - Batch operations can effectively reduce the extra loss due to the message granularity and improve the throughput. - - - **Pipeline**: Before the result of a message is returned, the next message is concurrently sent to the corresponding node. By increasing the number of concurrent messages (pipelines), the latency of each single concurrent request can be effectively reduced and the performance can be improved. DCF uses the asynchronous mode in multiple phases, such as log persistence, network sending, and log replication, to maximize the pipeline performance. - -- **Efficient flow control algorithm** - - Batching and pipelining can improve the throughput and performance of the entire system. However, if the batch size is too large, the latency of a single request is too long. As a result, the number of concurrent requests is too large, affecting the throughput and request latency. Therefore, the DCF designs a set of efficient and adaptive flow control algorithms, automatically detects parameters such as the network bandwidth, network sending latency, and number of concurrent requests, and adjusts batch and pipeline parameters to control service traffic injection. - - [Figure 2](#dcf2) shows the process of the flow control algorithm. - - **Figure 2** Process of the flow control algorithm - ![流控算法流程](https://cdn-mogdb.enmotech.com/docs-media/mogdb/reference-guide/process-of-the-flow-control-algorithm.jpg) - - The core algorithm process is as follows: - - 1. The primary DCF node periodically samples and calculates consensus information, including the end-to-end consensus latency, end-to-end consensus log bandwidth, and overall log playback bandwidth. - 2. Calculate a new control value: The primary node obtains the performance change trend based on the sampling result and historical results, adjusts the control direction and step based on the historical control value and change trend, and calculates a new control value for better performance. - 3. Update the control value after the control period expires. - 4. Continuously apply the control value to service traffic to control the frequency of service traffic injection. - -## Example - -Assume that there are three nodes in the cluster and their IP addresses are **192.168.0.11**, **192.168.0.12**, and **192.168.0.13**.

DCF provides capabilities such as log replication, cluster HA, and automatic leader election, and can forcibly start the minority and dynamically adjust traffic for log replication. In addition, multiple Paxos-based roles are provided and can be adjusted. + +DCF is a high-performance, highly mature, reliable, scalable, and easy-to-use independent basic library. Other systems can easily interconnect with DCF through interfaces to obtain the strong consistency, high availability, and automatic disaster recovery capabilities provided by the Paxos algorithm. + +## Architecture + +[Figure 1](#dcf) shows the functional architecture of the DCF, including the algorithm modules, storage module, communication module, and service layer. + +**Figure 1** Functional architecture of the DCF +![DCF功能架构图](https://cdn-mogdb.enmotech.com/docs-media/mogdb/reference-guide/functional-architecture-of-the-dcf.png) + +- **Algorithm modules:** + + Algorithm modules are implemented based on the Multi-Paxos protocol. Based on the service scenarios, and requirements for high performance and ecosystem, DCF has made many function extensions and performance optimization to enrich the functions compared with the basic Multi-Paxos protocol, and the performance is significantly improved in multiple deployment scenarios. It mainly includes a leader election module, a log replication module, a metadata module, and a cluster management module. + +- **Storage module:** + + For specific service scenarios and ultimate performance, the DCF extracts a set of public interfaces for log storage and implements a default high-performance storage module. For specific scenarios or users who have ultimate performance and cost requirements, you can connect the existing storage system to the log storage interface of DCF to meet specific requirements. This is one of the advantages of DCF as an independent third-party library. + +- **Communication module:** + + The communication module is implemented based on the Message Exchange Component (MEC) and provides the communication capability between DCF instances and the asynchronous event processing framework. The main features are as follows: multiple extensible communication protocols, unicast, broadcast, and loopback sending interfaces, asynchronous message processing framework, multi-channel mechanism, multi-priority queue, compression, and batch sending. + +- **Service layer:** + + The service layer is the basis for running the entire DCF and provides various basic services required for program running. For example, lock, asynchronous task scheduling, thread pool service, and timer. + +## Features + +- **Nodes can be added and deleted online, and the leader role can be handed over online.** + + Based on the standard Multi-Paxos, the DCF supports online node addition and deletion, and leader handover. This is more suitable for building a development ecosystem in a wide range of service scenarios. + +- **Priority-based leader election and policy-based majority are supported.** + + - **Policy-based majority**: In the classic Paxos theory, data can be submitted after the majority reaches a consensus. However, the majority is not specific and it cannot be guaranteed that one or some nodes can obtain complete data. In actual applications, the nodes that are geographically close to each other have strongly consistent data, but the nodes that are geographically far away from each other are always in a non-strongly consistent state. These nodes cannot be activated as the primary node for city-level disaster recovery. The policy-based majority mechanism enables users to dynamically configure one or more nodes to be strongly consistent and can be activated as the primary node immediately for disaster recovery. + - **Priority-based leader election**: You can specify the priority of each node. The DCF elects a leader node strictly according to the specified priority. The node with a lower priority is activated only when all the nodes with a higher priority are unavailable. + +- **Diversified node roles are provided.** + + In addition to typical roles such as Leader, Follower, and Candidate, the DCF also supports customized roles, for example, the Passive role (with logs, with data, without the right to be elected, and not participating in the majority voting) and the Log role (with logs, without data, without the right to be elected, and participating in the mkajority voting). With these node roles, DCF supports synchronous and hybrid (synchronous/asynchronous) multi-cluster deployment. + +- **Batch & Pipeline** + + - **Batch**: The DCF supports multi-level batch operations, including: + + - Combine multiple logs into a single message for sending. + - Combine multiple logs for writing to the disk. + - Combine multiple logs for replication. + + Batch operations can effectively reduce the extra loss due to the message granularity and improve the throughput. + + - **Pipeline**: Before the result of a message is returned, the next message is concurrently sent to the corresponding node. By increasing the number of concurrent messages (pipelines), the latency of each single concurrent request can be effectively reduced and the performance can be improved. DCF uses the asynchronous mode in multiple phases, such as log persistence, network sending, and log replication, to maximize the pipeline performance. + +- **Efficient flow control algorithm** + + Batching and pipelining can improve the throughput and performance of the entire system. However, if the batch size is too large, the latency of a single request is too long. As a result, the number of concurrent requests is too large, affecting the throughput and request latency. Therefore, the DCF designs a set of efficient and adaptive flow control algorithms, automatically detects parameters such as the network bandwidth, network sending latency, and number of concurrent requests, and adjusts batch and pipeline parameters to control service traffic injection. + + [Figure 2](#dcf2) shows the process of the flow control algorithm. + + **Figure 2** Process of the flow control algorithm + ![流控算法流程](https://cdn-mogdb.enmotech.com/docs-media/mogdb/reference-guide/process-of-the-flow-control-algorithm.jpg) + + The core algorithm process is as follows: + + 1. The primary DCF node periodically samples and calculates consensus information, including the end-to-end consensus latency, end-to-end consensus log bandwidth, and overall log playback bandwidth. + 2. Calculate a new control value: The primary node obtains the performance change trend based on the sampling result and historical results, adjusts the control direction and step based on the historical control value and change trend, and calculates a new control value for better performance. + 3. Update the control value after the control period expires. + 4. Continuously apply the control value to service traffic to control the frequency of service traffic injection. + +## Example + +Assume that there are three nodes in the cluster and their IP addresses are **192.168.0.11**, **192.168.0.12**, and **192.168.0.13**. The node IDs are 1, 2, and 3, and the node roles are Leader, Follower, and Follower. + +To use the DCF component, you need to set **enable_dcf** to **on** (disabled by default) and configure **DCF config** in the configuration file during FusionSphere OpenStack OM installation and deployment. + +Obtain the XML file template from **script/gspylib/etc/conf/centralized/cluster_config_template_HA.xml**. + +Each line of information is commented out.
