API Design
In order to get the information of table assignments for better debugging purpose, the following APIs are needed:
Get the leaders for all the tables in the cluster
GET /leader/tables
| lead controller resource enabled | lead controller resource disabled |
|---|---|
{ “leadControllerResource_0”: { “leadControllerId”: “Controller_localhost_9000”, “tableNames”: [table1, table2, ...] }, ... “leadControllerResource_23”: { “leadControllerId”: “Controller_localhost_9008”, “tableNames”: [table21, table22, ...] } } | {} |
Given a table name, return the partition id and lead controller instance id
GET /leader/tables/{tableName}
| lead controller resource enabled | lead controller resource disabled |
|---|---|
{ “leadControllerResource_0”: { “leadControllerId”: “Controller_localhost_9000”, “tableNames”: [table1] } } | {} |
