Yugabyte operations in DCT

This guide is for Delphix administrators and operators who perform YugabyteDB setup and provisioning tasks in DCT.

Perform YugabyteDB data operations using Delphix Data Control Tower (DCT) in conjunction with the Delphix Continuous Data (CD) Engine. The topics in this section walk through DCT-specific workflows to add YugabyteDB environments, upload the YugabyteDB connector toolkit, link YugabyteDB dSources using a supported ingestion method, and provision YugabyteDB virtual databases (VDBs).

Prerequisites

  • Access to DCT with appropriate administrative permissions

  • A running Delphix Continuous Data Engine

  • Network connectivity between DCT, the engine, and YugabyteDB hosts

  • Valid YugabyteDB OS and database credentials

  • YugabyteDB connector JSON file available for upload

Key components

  • Continuous Data Engine

    Executes YugabyteDB discovery, ingestion, and snapshot operations. For more information, read Connect a Continuous Data Engine in DCT.

  • YugabyteDB connector

    A JSON-based connector that enables the engine to detect YugabyteDB installations on registered hosts. For more information, read Upload the Connector.json in DCT.

  • Infrastructure connections (environments)

    Registered YugabyteDB hosts that DCT communicates with over SSH. For more information, read Add a YugabyteDB environment in DCT.

  • Source configurations

    Logical definitions that identify which YugabyteDB instance can be ingested as a dSource. For more information, read Create a source configuration for Connectors in DCT.

  • dSources

    Managed representations of YugabyteDB databases used to take snapshots, create bookmarks, link dSources, and provision VDBs.

  • VDBs

    Manage a VDB which is provisioned from a dSource or a VDB snapshot.

Supported ingestion methods

The YugabyteDB connector supports two ingestion approaches:

Ingestion type

Description

Staging Pull

Delphix works with Yugabyte Anywhere (YBA) to restore the most recent completed full backup and the most recent completed incremental backup from the same schedule. Backups must be stored in AWS S3 or Azure Blob Storage. NFS backup storage is not supported.
Seed Delphix creates an empty YugabyteDB universe in the staging environment. You load your data into that universe.

Limitations

  • V2P (Virtualize to Physical) is not supported.

  • Point-in-time restore is not supported. Each dSource snapshot reflects the latest completed backup, and you cannot select a specific incremental backup.

  • Yugabyte Anywhere (YBA) does not support assigning Masters on dedicated nodes.

  • Each VDB runs as its own YugabyteDB cluster. Ensure that its ports do not conflict with other YugabyteDB instances on the target host.

  • If the YugabyteDB version on a staging or target host is changed, the staging database and VDB must be recreated.
