Any api javaDoc?
It's a little bit hard to understand the design and the usage of these interfaces....

I got the design doc.

void createSchemaTemplate(
String templateName,
List<IMeasurementSchema>
)

VectorMeasurementSchema(String prefixPath, List<String> measurementNames, List<TSDataType> datatypes, List<TSEncoding> encodings)

MeasurementSchema(Sting path, TSDatatype datatype, TSEncoding encoding)

I think you may misunderstand the purpose of this PR.

What you should do in this PR is creating only one new interface createSchemaTemplate.
The IMeasurementSchema is an interface that could be a VectorMeasurementSchema or a MeasurementSchema.

VectorMeasurementSchema(String prefixPath, List<String> measurementNames, List<TSDataType> datatypes, List<TSEncoding> encodings) and MeasurementSchema(Sting path, TSDatatype datatype, TSEncoding encoding) are trying to tell you what informations are in these classes.

You cannot use the singletonList for datatypes and encodings directly.

Almost good to me.
I think we can also add a usage example in alignedTimeseriesSessionExample.
