I'm looking to implement an Athena federated query custom connector using
the arrow js lib. I'm getting stuck on figuring out how to encode a Schema
properly for the Athena GetTableResponse. I have found an example using
python that does something like this.. (paraphrasing...)
import pyarrow as pa
.....
return {
"@type": "GetTableResponse",
"catalogName": self.catalogName,
"tableName": {'schemaName': self.databaseName, 'tableName':
self.tableName},
"schema": {"schema":
base64.b64encode(pa.schema(....args...).serialize().slice(4)).decode("utf-8")},
"partitionColumns": self.partitions,
"requestType": self.request_type
}
What i'm looking for is the js equivalent of
pa.schema(....args...).serialize()
Is there one? If not, could someone point me in the right direction of how
to code up something similar?
