TableSpec

TableSpec is the model used to create the schema of the table. It is in the format:

{
  "<name of column>": {
    "type": "<type of column>"
  }
}

Supported types

Simple Datatypes:

bool: boolean
int: 32-bit integer
int32: 32-bit integer
long: 64-bit integer
int64: 64-bit integer
double: 64-bit float
date: 64-bit date

Possible precisions: ms(millisecond)

date64: 64-bit date
string: string
binary: binary
geometry: binary

Geometry can be represented in 3 formats:

Complex Datatypes:

Some types need to have precision value stated in the schema. Precision can be stated by putting the precision value in brackets after the timestamp like this: time<ns> Possible precisions are stated below the necessary types

time: 64-bit time

Possible precisions: us(microsecond), ns(nanosecond)

time64: 64-bit time

Possible precisions: us(microsecond), ns(nanosecond)

timestamp: timestamp

Possible precisions: s(second), ms(millisecond), us(microsecond), ns(nanosecond)

list: list

Possible precisions: item: Supported complex type list<item: bool>

map: map

Possible precisions: Supported complex type, Supported complex type map<bool, int>

List and map complex datatypes can only contain a subset of the supported simple datatypes. Supported simple datatypes that can be put into the list and map are:

bool
int
int32
long
int64
double
string
binary
