AvroSchemaBuilder

Creates a new schema builder with the given record name

Sets the namespace for the record

Sets the documentation for the record

Adds a field with the given name and type

Adds a field with documentation

Adds a nullable field (shorthand for field(name, AvroType::Nullable(…)))

Adds an integer field

Adds a long (i64) field

Adds a float field

Adds a double field

Adds a string field

Adds a boolean field: an Avro int, as Kinetica stores a boolean (give the column the boolean property). The struct’s bool field must be written as an int, with #[serde(with = “gpudb_api::avro_schema_builder::bool_as_int”)] (see bool_as_int); unannotated, it fails to encode.

Adds a bytes field

Adds a timestamp field (long type, typically milliseconds since epoch)

Adds a nullable string field

Adds a nullable int field

Adds a nullable long field

Adds a nullable double field

Adds a nullable bytes field

Builds the Avro schema JSON string

Builds the schema and leaks it to get a &‘static str

This is useful for implementing KineticaRecord::avro_schema() which requires returning &‘static str. The memory is intentionally leaked since schemas are typically created once and live for the program’s lifetime.

use gpudb_api::avro_schema_builder::{AvroSchemaBuilder, AvroType};

let schema: &'static str = AvroSchemaBuilder::new("MyRecord")
    .int_field("id")
    .string_field("name")
    .build_static();
