Getting Started with Common Practices

After purchasing and connecting to a GeminiDB Cassandra DB instance, you can view common practices to better use it.

**Table 1** Common practices
Practice		Description
Database rules	Basic Design	Describes basic design specifications of GeminiDB Cassandra.
	Database Objects	Describes rules of using database objects.
	Database Usage	Describes constraints of using databases.
	Queries	Describes rules of querying GeminiDB Cassandra.
Instance modifications	Changing an Instance Name	Describes how to change the name of a GeminiDB Cassandra instance to identify different instances.
	Resetting the Administrator Password	Describes how to change your administrator password. For security reasons, change it periodically.
	Changing vCPUs and Memory of an Instance	Describes how to change the CPU or memory of your instance to suit your service requirements.
Data backup	Managing Automated Backups	Describes how GeminiDB Cassandra API automatically creates backups for a DB instance during a backup window and saves the backups based on the configured retention period.
	Managing Manual Backups	Describes how to create manual backups for a DB instance. These backups can be used to restore data for improved reliability.
	Setting a Cross-Region Backup Policy	Describes how to set a cross-region backup policy for a DB instance. Then for disaster recovery, you can restore backups to a new instance in another region.
	Creating a Table-level Backup	Describes how to create a table-level backup for a DB instance. If a database or table is deleted, maliciously or accidentally, backups can help restore your data.
Data restoration	Restoring Data to a New Instance	Describes how to restore an existing automated or manual backup to a new instance. The restored data is the same as the backup data.
Data restoration	Restoring a Backup to a Specific Point in Time	Describes how to use an automated backup to restore instance data to a specified point in time.
Log management	Slow Query Logs	Describes how to view slow query logs of a GeminiDB Cassandra database. The unit of the execution time is ms. You can identify the SQL statements that take a long time to execute and tune them based on slow query logs.
