SQL Statements for MariaDB Xpand 5.3

Overview

Structured Query Language (SQL) statements enable the reading and writing of data within the database. MariaDB Xpand implements classic and modern SQL database features.

SQL Statement

Description

ABORT

ALTER BINARY LOG

ALTER BINLOG

ALTER CLUSTER

Contains several sub-statements that can be used to alter an Xpand cluster

ALTER CLUSTER ADD

Modifies an Xpand cluster, triggering group change to add a new Xpand node to the cluster

ALTER CLUSTER DROP

Modifies an Xpand cluster, triggering a group change to explicitly removing a failed node from the cluster

ALTER CLUSTER REFORM

Modifies an Xpand cluster, triggering a group change to apply changes made by previous ALTER CLUSTER statements

ALTER CLUSTER RELOAD RSA

Reloads the RSA key pair used by the sha256_password authentication plugin that are defined by sha256_password_public_key_path and sha256_password_private_key_path

ALTER CLUSTER RELOAD SSL

Reloads the TLS/SSL certificates and keys that are defined by ssl_cert and ssl_key

ALTER CLUSTER RESET ALERTER

ALTER CLUSTER RESIZE DEVICES

Modifies an Xpand cluster, resizing the device1 files on all Xpand nodes

ALTER CLUSTER SET MAX_FAILURES

Modifies an Xpand cluster, configures the Rebalancer to sets the number of replicas and acceptors to maintain, specifying the maximum number of Xpand nodes that can fail simultaneously without data loss

ALTER CLUSTER SOFTFAIL

Modifies the Xpand cluster, configures the Rebalancer to move data off of the specified Xpand nodes so that they can be removed from the cluster
