Deploy Spider Federated Topology with MariaDB Enterprise Server 10.6

This procedure describes the deployment of the Spider Federated topology with MariaDB Enterprise Server 10.6.

This procedure incrementally deploys MariaDB Enterprise Spider on an existing MariaDB Enterprise Server 10.6 deployment.

In the Spider Federated topology, a Spider Node contains one or more "virtual" Spider Tables. A Spider Table does not store data. When a Spider Table is queried, the Enterprise Spider storage engine uses a MariaDB foreign data wrapper to read from and write to a Data Table on a Data Node.

This procedure has 3 steps, which are executed in sequence.

This page provides an overview of the topology, requirements, and deployment procedure.

The topology described is representative of basic product capabilities. MariaDB products can be deployed to form other topologies, leverage advanced product capabilities, or combine the capabilities of multiple topologies.

Prerequisites

If you have not yet deployed MariaDB Enterprise Server on the Spider Node and Data Node, first deploy a topology containing MariaDB Enterprise Server. Several topologies are documented.

Support

Production customers can obtain support by submitting a support case.

Components

The following MariaDB Enterprise components are used by this topology:

Component

Function

MariaDB Enterprise Server

Modern SQL RDBMS with high availability, pluggable storage engines, hot online backups, and audit logging.

MariaDB Enterprise Spider

Storage engine used by Spider Tables to read from and write to Data Tables using the MariaDB foreign data wrapper.

Term Definitions

Term

Definition

Data Node

A Data Node is a MariaDB Enterprise Server node that contains one or more Data Tables.

Data Table

A Data Table stores data for a Spider Table. When a Spider Table is queried, the Enterprise Spider storage engine uses the MariaDB foreign data wrapper to read from and write to the Data Table on a Data Node. The Data Table must be created on the Data Node with the same structure as the Spider Table. The Data Table must use a non-Spider storage engine, such as InnoDB or ColumnStore.

ODBC Data Source

An ODBC Data Source relies on an ODBC Driver and an ODBC Driver Manager to query an external data source.

ODBC Driver

An ODBC Driver is a library that integrates with a ODBC Driver Manager to query an external data source.

ODBC Driver Manager

An ODBC Driver Manager allows applications to use ODBC Drivers.

Spider Node

A Spider Node is a MariaDB Enterprise Server node that contains one or more Spider Tables.

Spider Table

A Spider Table is a virtual table that does not store data. When a Spider Table is queried, the Enterprise Spider storage engine uses foreign data wrappers to read from and write to Data Tables on Data Nodes or ODBC Data Sources.

Topology

Spider Federated Topology

In the Spider Federated topology, a Spider Node contains one or more "virtual" Spider Tables. A Spider Table does not store data. When a Spider Table is queried, the Enterprise Spider storage engine uses a MariaDB foreign data wrapper to read from and write to a Data Table on a Data Node.

The Spider Federated topology consists of:

  • One MariaDB Enterprise Server node is a Spider Node

  • One MariaDB Enterprise Server node is a Data Node

The Spider Node:

  • Contains one or more Spider Tables

  • Uses the Enterprise Spider storage engine plugin for Spider Tables

  • Uses a MariaDB foreign data wrapper to query the Data Table on the Data Node

The Data Node:

  • Contains a Data Table for each Spider Table

  • Uses a non-Spider storage engine for each Data Table, such as InnoDB or ColumnStore

For additional information, see "Spider Federated Topology".

Requirements

These requirements are for the Spider Federated topology when deployed with MariaDB Enterprise Server 10.6.

Node Count

  • One or more MariaDB Enterprise Server nodes must be deployed as Spider Nodes. The Spider Nodes contain Spider Tables.

  • One or more MariaDB Enterprise Server nodes must be deployed as Data Nodes. The Data Nodes contain Data Tables.

In alignment to the enterprise lifecycle, the Spider Federated topology with MariaDB Enterprise Server 10.6 is provided for:

  • CentOS 7 (x86_64)

  • CentOS 8 (x86_64 / ARM64)

  • Debian 9 (x86_64 / ARM64)

  • Microsoft Windows (x86_64)

  • Red Hat Enterprise Linux 7 (x86_64)

  • Red Hat Enterprise Linux 8 (x86_64 / ARM64)

  • SUSE Linux Enterprise Server 12 (x86_64)

  • SUSE Linux Enterprise Server 15 (x86_64 / ARM64)

  • Ubuntu 18.04 (x86_64 / ARM64)
