class blazingdb::manager::Context¶

This is the main component of the transport library.

Manage and group the Node ‘s (task nodes) to be used by an specific query.

Public Functions

explicit Context(const uint32_t token, const std::vector<Node> &taskNodes, const Node &masterNode, const std::string &logicalPlan, const std::map<std::string, std::string> &config_options, const std::string current_timestamp)¶

std::shared_ptr<Context> clone()¶

int getTotalNodes() const¶

std::vector<Node> getAllNodes() const¶

std::vector<Node> getAllOtherNodes(int selfNodeIndex) const¶

std::vector<Node> getWorkerNodes() const¶: RAL instances that will run the query.

Node getNode(int node_index) const¶

Node getNode(const std::string &id) const¶

const Node &getMasterNode() const¶: A single unique RAL instance that helps to the messages transmition and processesing between worker RAL’s e.g.: see SampleToNodeMasterMessage
