SQL Reference
For distributed databases with massive storage requirements, table data volumes inevitably grow over time. This growth often leads to insufficient cluster capacity and computing power (CPU). In such cases, efficient and reliable cluster expansion becomes essential. While it is ideal to plan for future growth during initial system design, it is usually impractical to over-invest in resources too early. Therefore, we recommend that you regularly plan and perform database expansion operations.
In YMatrix, you can choose between GUI-based expansion or command-line online expansion. We recommend using the GUI for its simplicity and ease of use. Currently, YMatrix supports online smooth expansion (read and write operations are unaffected during expansion) and flexible configuration of table data distribution.
Are the catalogs consistent between old and new nodes during expansion?
What is the impact on other queries during expansion?
