The simplest query logic may be using:
```
LocalExecutionPlanner.getInstance()
.metadata
.indexScan(
new QualifiedObjectName(<database>, <table>),
Collections.emptyList(),
Arrays.asList(<yourAttributes>),
new MPPQueryContext(new QueryId("Processor query")));
```
And it will return Map<String, List<DeviceEntry>>, ignore the key (database,
for tree view), and the List<DeviceEntry> is all you needed.
