Treat byte as string or do base64 serialization, but not applicable to all use cases.

Most NoSQL/RDBMS systems support blob/byte[], the common use cases are either small attachments or encrypted fields. Generally encoding/decoding them to base64 is seen as inefficient as it makes the storage larger and adds to compute cycles.

So currently Nebula JDBC doesn’t support BLOB which is part of that specification as well. And from our perspective we’re trying to support compatibility with Neo4j which supports byte[] and it is used in our application.

Here are the types for JDBC

Here are the types for Neo4j
