The Apache Avro Rust SDK 0.22.0 release is a large release with lots of features, fixes and breaking changes. It is strongly recommended to read the Breaking changes and New features sections of the changelog.

What's changed

Breaking changes

• Resolve schema(ta) in the builder of Writer by @Kriskras99 in #328
  • The builder now returns an AvroResult
• Rework schema compatibility by @Kriskras99 in #342
  • SchemaCompatiblity::can_read and SchemaCompatiblity::mutual_read now return a Compatiblity type
• Bump MSRV from 1.85 to 1.88 by @Kriskras99 in #342, #348
• Schema::Duration now has a FixedSchema allowing access to attributes and Serialize and Deserialize is implemented for apache_avro::Duration by @jdarais in #382
• AvroSchema and AvroSchemaComponent are no longer behind the derive feature and have moved from apache_avro::schema::derive to apache_avro::serde by @martin-g in #394 and @Kriskras99 in #433
• Change the implementation of AvroSchemaComponent for Uuid from Schema::Uuid(String) to Schema::Uuid(Fixed(name: "org.apache.avro.rust.Uuid", size: 16)) and allow overwriting a field's schema with the with attribute when using #[derive(AvroSchema)] by @Kriskras99 in #397, #558
  • When #[avro(with)] is specified without an argument, it will call the get_schema_in_ctxt(&mut HashSet<Name>, NamespaceRef<'_>) -> Schema in the same module as specified by #[serde(with)]
  • When #[avro(with = path::to::some_fn)] is specified with a path, the function it's pointing to will be called with two parameters &mut HashSet<Name>, NamespaceRef<'_>
  • When #[avro(with = || {})] is specified with a closure, that closure is invoked
  • The name of the schema for uuid::Uuid is org.apache.avro.rust.uuid
  • The schema for Uuid can be changed back to a Schema::Uuid(String) using #[avro(with = || Schema::Uuid(UuidSchema::String))] on a field with a Uuid and setting human_readable to true
• Replace the From<&str> implementations for Name and Alias with TryFrom<&str>, TryFrom<String>, and FromStr as the conversion is not fallible by @Kriskras99 in #423
• Rework SpecificSingleObjectWriter removing ::with_capacity and changing write_avro_datum_ref to also take a &NamesRef parameter by @Kriskras99 in #445
• Remove the default field from FixedSchema as it is not in the specification by @Kriskras99 in #460
• AvroSchemaComponent::get_schema_in_ctxt now takes a &mut HashSet<Name> parameter for the named_schemas parameter by @Kriskras99 in #471
• Replace the Schema::map{,_with_attributes} and Schema::array{,_with_attributes} with builders allowing the user to set more fields by @martin-g in #472
  • This also adds Schema::r#enum, Schema::fixed and Schema::record
• Stricter schema parsing by @Kriskras99 in #479
  • This now rejects schemas that were previously accepted by this library, they were already rejected by parsers in different languages
• Alias::name and Alias::namespace now return references by @Kriskras99 in #486
• Remove unused order and position fields in RecordField by @Kriskras99 in #491
• Rework Name to be more performant which requires changing the SchemaNameValidator trait by @Kriskras99 in #493
  • The regex returned by SchemaNameValidator::regex must have a capture group named name which captures the unqualified name when not overriding the SchemaNameValidator::validate function
  • The SchemaNameValidator::validate must now return the start byte of the unqualified name
• Support enums and tuples in SchemaAwareSerializer, implement SchemaAwareDeserializer and document the mapping between the Serde and Avro data models by @Kriskras99 in #512, #558
  • The SchemaAware* now have specific requirements for what input they accept, so type definitions might need to be modified to make them work with the new code (especially for enums and tuples)
  • This also makes human_readable configurable per reader and writer instance
  • Array and Map serialisation will not write the block size in bytes unless configured to do so, allowing unbuffered serialisation
  • The AvroSchemaComponent implementation for std::time::Duration has changed to match the (de)serialisation implementation as defined by Serde
    • It is now a Schema::Record(name: "org.apache.avro.rust.Duration", fields: ["secs": "org.apache.avro.rust.u64", "nanos": "long"])
  • The AvroSchemaComponent implementation for BigDecimal is now a Schema::String matching the (de)serialisation implementation as defined by bigdecimal
    • It can be changed back to a Schema::String using #[serde(with = "apache_avro::serde::bigdecimal"), avro(with)] on a field with a BigDecimal
  • The SchemaAwareDeserializer does not support schema resolution, for that use the old from_value implementation (see #575)

New features

• Make DeflateSettings::compression_level public by @EmilyMatt in #335
• Support fixed as a type for uuid by @Kriskras99 in #339
• Don't depend on Serde to provide fields in the right order by @Kriskras99 in #351
  • It is still recommended to match the field order between the type and the schema as out-of-order serialisation incurs a performance penalty
• Support the #[serde(flatten)] attribute by @Kriskras99 in #359, #448
  • This attribute is not supported when using apache_avro::serde::to_value
• Use the Serde attributes and check for conflict with the Avro attributes by @Kriskras99 in #377
  • This deprecates the Avro attributes for which the value must always match the Serde attribute:
    • Container attributes:
      • #[avro(name = "..")] -> #[serde(rename = "..")]
      • #[avro(rename_all = "..")] -> #[serde(rename_all = "..")]
    • Variant attributes:
      • #[avro(rename = "..")] -> #[serde(rename = "..")]
    • Field attributes:
      • #[avro(alias = "..")] -> #[serde(alias = "..")]
      • #[avro(rename = "..")] -> #[serde(rename = "..")]
      • #[avro(skip)] -> #[serde(skip)]
  • On nightly compilers, using deprecated attributes will throw a compiler warning
• Support the #[serde(transparent)] attribute on structs by @Kriskras99 in #398
• Implement AvroSchemaComponent for char, u64, u128, i128, () by @Kriskras99 in #414, #486, #558
  • char: Schema::String
  • u64: Schema::Fixed(name: "org.apache.avro.rust.u64", size: 8)
  • u128: Schema::Fixed(name: "org.apache.avro.rust.u128", size: 16)
  • i128: Schema::Fixed(name: "org.apache.avro.rust.i128", size: 16)
  • (): Schema::Null
• Add RecordSchemaBuilder::try_name which accepts any TryInto<Name> and make RecordFieldBuilder::name take any Into<String> by @martin-g in #429
• Move and rename the serde_avro_* modules to apache_avro::serde::*, the old modules are still available but deprecated and will be removed in a future release by @Kriskras99 in #430
  • apache_avro::serde_avro_bytes -> apache_avro::serde::bytes
  • apache_avro::serde_avro_bytes_opt -> apache_avro::serde::bytes_opt
  • apache_avro::serde_avro_fixed -> apache_avro::serde::fixed
  • apache_avro::serde_avro_fixed_opt -> apache_avro::serde::fixed_opt
  • apache_avro::serde_avro_slice -> apache_avro::serde::slice
  • apache_avro::serde_avro_slice_opt -> apache_avro::serde::slice_opt
• Add posibility to append values to writer without validating by @Kriskras99 in #447
  • This renames Writer::append to Writer::append_value although the old function currently still exists and is deprecated
  • This adds Writer::unvalidated_append_value and Writer::unvalidated_append_value_ref which skip the validation step
• Rework the documentation by @Kriskras99 in #451
• The introduction to Avro itself was moved to the documentation::primer module
• Using the crate the "Avro" way was moved to the documentation::generic module
• Using the crate the "Serde" way was moved to the serde module
• Calculating schema fingerprints was moved to the Schema::fingerprint function
• Custom name validators was moved to the validator module
• Custom schema equality was moved to the schema_equality module
• Document #[derive(AvroSchema)] in the serde module
• Suggest the boolean type when a schema contains a type named bool that does not resolve by @Kriskras99 in #459
• Add support for resetting a Writer backed by a clearable buffer by @Kriskras99 in #469
• Make Schema::denormalize public by @Kriskras99 in #470
• Allow types implementing AvroSchemaComponent to provide a default value by @Kriskras99 in #477
• Custom Debug implementations for *Schema types hiding empty fields for more readability by @Kriskras99 in #488
• Add a builder for unions: UnionSchemaBuilder by @Kriskras99 in #486
• Replace the from_avro_datum* functions with GenericDatumReader by @Kriskras99 in #496
  • The functions are still available, but are deprecated and will be removed in a future version
• Replace the to_datum* functions with GenericDatumWriter by @Kriskras99 in #499
  • The functions are still available, but are deprecated and will be removed in a future version
• Support #[serde(remote = "..")] by @Kriskras99 in #564
• Support deriving AvroSchema on enums and tuples by @Kriskras99 in #569
  • If some enum or tuple is not supported, and you think it should, please open an issue!
• Allow to supply own names when using Value::resolve and Value::Validate by @Kriskras99 in #579
