The Search service adds full-text index capability to ApsaraDB for HBase Enhanced Edition by linking it to a Big Data Service (BDS) cluster. This topic describes how to activate the service and verify that all instances are running.
Prerequisites
Before you begin, ensure that you have:
An ApsaraDB for HBase Enhanced Edition cluster
A Big Data Service (BDS) cluster in the same virtual private cloud (VPC) as the HBase cluster
If you don't have these clusters, purchase them from the ApsaraDB for HBase product page or create them directly in the HBase console using Create HBase Cluster and Create BDS Cluster.
Activate the Search service
After you associate a BDS cluster with an HBase cluster, the BDS cluster cannot be linked to any other cluster or used for other purposes. Proceed with caution.
During activation, both the HBase cluster and BDS cluster are automatically upgraded to the latest version. The system may become unstable during the upgrade. Activate the service during off-peak hours to minimize impact on your workloads.
Log in to the ApsaraDB for HBase Enhanced Edition console and click Full-text Index in the left-side navigation pane.
Select the BDS cluster to associate.
NoteOnly BDS clusters in the same VPC as your HBase Enhanced Edition cluster are available. A BDS cluster already linked to another HBase cluster in a full-text index configuration cannot be selected.
Select the cluster type. The Search service requires large memory capacity and high disk I/O performance. Use a high-capacity standard solid-state drive (SSD) and local SSD for the cluster. If you have questions about cluster specifications, contact customer service through the ApsaraDB for HBase Q&A DingTalk group or submit a ticket.
Verify the activation
After activation, three instances appear in the console:
| Instance type | Example ID |
|---|---|
| ApsaraDB for HBase Enhanced Edition | ld-t4n33q6tj8hexxxx |
| BDS | bds-t4n579vl2f74xxxx |
| Search | ld-t4n33q8he022kxxxx-m1-se |
In the Service/Version/Primary Instance column, both the BDS instance and the Search instance show the associated HBase instance ID (ld-t4n33q8he022kxxxx).
The Search service is ready when all three instances show a status of Running.
What's next
Use the Search service to run full-text queries on your HBase data.
Monitor the Search instance status in the HBase console.
