Serializing with Primitive Data Types
Serializing with primitive data types supports character strings, binary strings, and numeric data types. Below are a few (non-exhaustive) examples of serialization with primitive data types. See the full list of supported primitive types.
Character String
With the following DDL and query:
CREATE STREAM primitiveExample (
"stringValue" VARCHAR
) WITH (
'topic' = 'primitiveExample', 'value.format' = 'Primitive'
);
SELECT * FROM primitiveExample;
For the given input records:
// input record bytes as String
abc
// output will read bytes as String
{ "stringValue": "abc" }
// input record bytes as Integer
123
// output record will read bytes as String
{ "stringValue": "\u0000\u0000\u0000{" }
Numeric
With the following DDL and query:
CREATE STREAM primitiveExample (
"intValue" INTEGER
) WITH (
'topic' = 'primitiveExample', 'value.format' = 'Primitive'
);
SELECT * FROM primitiveExample;
For the given input records:
// input record bytes as Integer
123
// output will read bytes as Integer
{ "intValue": 123 }
// input record bytes as String
abcd
// output will be read bytes as String
// It's also likely for other string bytes that there will be a
// deserialization error while attempting to cast String to Integer
{ "intValue": 1633837924 }
Binary String
With the following DDL and query:
CREATE STREAM primitiveExample (
"bytesValue" VARBINARY
) WITH (
'topic' = 'primitiveExample', 'value.format' = 'Primitive'
);
SELECT * FROM primitiveExample;
For the given input records:
// input record bytes as Bytes
aG93ZHk=
// output will read bytes as Bytes
{ "bytesValue": "aG93ZHk=" }
