Part 1: Latest Updates on PieCloudDB Database


  • Dynamic Configuration of Query Clusters 

PieCloudDB's latest kernel V2.14.0 introduces a new feature for dynamically configuring query clusters. This feature enables scalable parallelized queries, enhancing the ability to utilize underlying resources in parallel for a single query and accelerating the response time. 


The dynamic configuration of query clusters is primarily applicable to scenarios involving a single SELECT query. The size of the query cluster can be dynamically adjusted through the parameter “pdb_parallel_factor”. 


  • Schedule Feature 

PieCloudDB's visual cloud-native platform has added a new feature for scheduled tasks. Scheduled tasks support the automatic execution of tasks at designated times or intervals, applicable for regular background tasks, report generation, garbage data cleanup, data updates, and automated operations, further facilitating database administrators and developers. 

This feature is currently available only in the Enterprise Edition

  • Data Loading Feature 

PieCloudDB's cloud-native platform has introduced a new data loading feature. Data loading supports extracting data from various databases and loading it into PieCloudDB, with the process managed and monitored through a visual cloud-native platform. Users can perform full data migration and backup with visual and refined management by configuring data sources, data flows, and job scheduling on the platform. 

This feature is currently available only in the Enterprise Edition

  • Batch Grant Privilege Feature
