…a parquet file in Parquet Data Source: enums, repeated enums, message, repeated message, repeated primitives (#140) * feat: add parquet source specific configs [#99] * feat: extract enums into their own file [#99] * feat: create a KafkaSource factory [#99] * feat: create a common interface for all serializers [#99] * feat: create a ParquetFileSource and its builder [#99] * feat: add ParquetFileSourceFactory [#99] * feat: add SourceFactory to create sources [#99] * feat: create skeleton for a basic parquet file reader [#99] * feat: create skeleton for two split assigners - added split assigners to assign splits based on timestamp in url and based on index in filepaths array [#99] * feat: create skeleton for ParquetFileRecordFormat [#99] * feat: add more methods in ParquetFileSourceFactory - add methods to get FileSplitAssigner and FileRecordFormat based on configs - pass StencilClientOrchestrator to SourceFactory as well when creating the source [#99] * feat: add runtime dependency for parquet-column into dagger-common - this is required for parsing the parquet SimpleGroup data structure into Java objects. [#99] * feat: add an interface for parquet data type parser [#99] * feat: implement parquet parsers for some primitive data types - implement parsers for int32, int64 and boolean parquet data types [#99] * feat: handle null args for ParquetDataTypeParser - remove abstract method serializer from the interface as it is not required [#99] * feat: implement parquet parser for float [#99] * feat: implement parquet parsers for binary string [#99] * feat: implement parquet parsers for double primitive type [#99] * feat: implement parquet parsers for enum [#99] * feat: implement parquet parser for timestamp [#99] * feat: add check for missing logical type annotation - return DaggerDeserializationException instead of ClassCastException when logical type is incorrect [#99] * feat: add validation for missing logical type annotation - return DaggerDeserializationException instead of ClassCastException when logical type is incorrect [#99] * feat: add a validation factory for parquet schema checks [#99] * feat: add more checks to SimpleGroupValidation - change the class to a usual class instead of a factory class [#99] * feat: apply validations to ParquetBoolean parser - ParquetDataTypeParser.getValueOrDefault() now returns the default value only if the deserialized value is null. [#99] * feat: apply validations in ParquetTimestampParser [#99] * feat: apply validations in ParquetInt64Parser [#99] * feat: apply validations in ParquetInt32Parser [#99] * feat: apply validations in ParquetFloatParser [#99] * feat: apply validations in ParquetDoubleParser [#99] * feat: apply validations in ParquetEnumParser [#99] * feat: apply validations in ParquetStringParser [#99] * feat: implement parquet data type identifier - this will be similar to a protobuf field descriptor and will be used for uniquely identifying a primitive type + logical type combination [#99] * feat: add canHandle as an abstract method in ParquetDataTypeParser - if a parser implementing ParquetDataTypeParser is able to parse the field name present in the simple group(as passed in the method signature), this function will return a true value, otherwise false. [#99] * feat: change signature of ParquetDataTypeParser.getValueOrDefault() - does not need a simple group anymore [#99] * bugfix: use Objects.equals instead of ==` - `==` returns false while comparing Object instances. It will work only in case of enums. [#99] * refactor: opt to use safer Objects.equals - use fieldName itself to extract logical and primitive type [#99] * feat: mark constructor as public for ParquetDataTypeID [#99] * feat: add factory method for producing ParquetDataTypeParser [#99] * feat: add method to deserialize from simple group in BooleanPrimitiveTypeHandler [#99] * feat: add method to deserialize from simple group in DoublePrimitiveTypeHandler [#99] * feat: add method to deserialize from simple group in FloatPrimitiveTypeHandler [#99] * feat: add method to deserialize from simple group in IntegerPrimitiveTypeHandler [#99] * feat: add method to deserialize from simple group in LongPrimitiveTypeHandler [#99] * feat: add method to deserialize from simple group in StringPrimitiveTypeHandler [#99] * feat: add method to deserialize from simple group in ByteStringPrimitiveTypeHandler [#99] * feat: rename interface method and its usages - this will add support for parquet simple group [#99] * feat: add support for transforming simple group in EnumProtoHandler [#99] * feat: add support for transforming simple group in TimestampProtoHandler [#99] * feat: undo adding factory method to create ParquetDataTypeParser - this won't be needed as the same factory method will be used to create handlers for both parquet and kafka [#99] * feat: add factory method in SimpleGroupValidation [#99] * feat: add a test proto for testing parquet source [#99] * feat: support transforming of simple group in PrimitiveProtoHandler [#99] * feat: add factory method to convert simple group to row - this will handle primitive types only for now plus timestamps. [#99] * feat: add a simple group deserializer [#99] * feat: rename interface method to transformFromKafka [#99] * feat: add and implement transformFromParquet [#99] * feat: move SimpleGroupValidation to another package [#99] * feat: delete io.odpf.dagger.common.serde.parquet.parser package - the proto handlers will be used to parse simple group as well [#99] * feat: call transformFromParquet instead in RowFactory method [#99] * feat: throw exception for bounded kafka source [#99] * feat: stop passing stencil to ParquetFileSource and its downstream components [#99] * feat: throw exception for unbounded parquet source [#99] * feat: add constructor to SourceDetails [#99] * feat: make both JsonDeserializer and ProtoDeserializer implement DaggerDeserializer<Row> [#99] * feat: Add a deserializer factory - this factory produces instances of deserializers for parsing data from parquet files and kafka source based on the configured input schema data type [#99] * feat: add new field and constructor to Stream POJO - Stream now also maintains details about its source boundedness and type [#99] * feat: add method to create data sources with deserializer in StreamBuilder - also add constructor method with stencil in args [#99] * feat: add a 2 argument constructor for StreamBuilder - init stencil to null [#99] * feat: call StreamBuilder with stencil from ProtoDataStreamBuilder - add tests to check cases related to new stream config SourceDetails [#99] * feat: add tests to check cases related to new stream config SourceDetails [#99] * feat: enable Mockito plugin for mocking of final methods - check this https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2#mock-the-unmockable-opt-in-mocking-of-final-classesmethods - this is needed for testing the default case of switch statements where enum is used as the expression. Check out DeserializerFactoryTest.java [#99] * feat: move DeserializerFactory to another package and add tests [#99] * feat: add a class for populating source specific stream metrics [#99] * feat: delegate metrics away from StreamBuilder to StreamMetrics [#99] * feat: create stream with source details from SourceFactory [#99] * feat: migrate to using buildStream in StreamBuilder implementations - delete unnecessary methods [#99] * feat: rename buildStream to build - update tests [#99] * feat: add tests for StreamMetrics [#99] * feat: refactor StreamsFactory - use method reference [#99] * feat: refactor StreamMetricsTest - delete redundant statement [#99] * feat: add tests for DeserializerFactory [#99] * feat: stop sending StreamConfig to ParquetFileRecordFormat - the class does not require it at the moment [#99] * feat: cleanup test and edit exception message [#99] * feat: refactor SourceFactory and add tests - throw DaggerConfigurationException instead of IllegalConfigurationException [#99] * feat: refactor DeserializerFactory - throw DaggerConfigurationException instead of IllegalConfigurationException [#99] * feat: refactor StreamBuilder - throw DaggerConfigurationException instead of IllegalConfigurationException - fix tests [#99] * feat: add custom exception for simple group parsing failures - this exception is to be thrown whenever there is a failure during parsing of fields within a simple group to other java data types [#99] * feat: throw SimpleGroupParsingException from SimpleGroupDeserializer - stop asserting for the exception message as it is coming from downstream [#99] * feat: change exception thrown during simple group parsing in TimestampProtoHandler - throw SimpleGroupParsingException instead of InvalidDataTypeException - update tests [#99] * feat: build FileSource from ParquetFileSource in SourceFactory - get instance of ParquetFileSourceBuilder using static method - update tests [#99] * feat: add a Builder nested class inside ParquetFileRecordFormat [#99] * feat: delete factories for kafka and parquet source - move the implementation into SourceFactory instead - this is because factories calling other factories is a bad pattern. Factories will either call dependencies or builders to create different types of objects implementing the same interface - remove broken test code [#99] * feat: use Google precondition checks instead of flink ones [#99] * feat: Create StreamType and its implementations - this will encapsulate the source, deserializer and schema type for a particular Flink DataStream [#99] * feat: make abstract methods public in StreamType and its implementations [#99] * feat: add tests for KafkaSourceJsonType [#99] * feat: return StreamType from build method [#99] * feat: refactor tests [#99] * feat: add tests for ParquetSourceProtoType [#99] * feat: add tests for KafkaSourceProtoType [#99] * feat: add a POJO for holding parquet file split with its instant [#99] * feat: implement chronology ordered split assigner and add tests [#99] * feat: rename files and tests for streamtype [#99] * feat: move the builder class as a nested class inside ParquetFileSource - update usages and delete ParquetFileSourceBuilder [#99] * feat: allow chronology ordered split assigner to be initialized with zero splits [#99] * feat: add tests for ParquetFileSource and add more validations - refactor method names and update usages [#99] * feat: make provider class as nested class inside PrimitiveReader - update usages and delete PrimitiveReaderProvider [#99] * feat: add tests for ParquetFileRecordFormat - make constructor private since builder is used - restoreReader needs to be implemented. This is a TODO and needs to be implemented once checkpointing is added. Throwing a runtime exception for now [#99] * feat: add few tests for PrimitiveReader [#99] * feat: implement PrimitiveReader and add tests - add dependency of `parquet-protobuf` required for using ParquetFileReader. This reader is needed for reading row groups out of the parquet file - add test parquet files in resources [#99] * feat: throw runtime exception if error in creating parquet reader - create a custom runtime exception [#99] * feat: make the type information provider and reader provider functions serializable - flink requires components which need to be transferred over the wire to different nodes to be serializable. If not made serializable, java.io.NotSerializableException is thrown at runtime. [#99] * feat: fix checkstyle formatting issues [#99] * feat: fix checkstyle issues in split assigner - remove magic numbers and use constants [#99] * feat: fix checkstyle formatting issues in stream type impls - make un-changing variables as class level constants [#99] * feat: make ParquetFileSource serializable - needed as this may be transferred over the wire at runtime [#99] * feat: remove serialization from PrimitiveReader - primitive reader is instantiated from primitive reader provider interface which is already serializable. Also, the outer wrapper of FileRecordFormat is also serializable. Since the reader is not transferred over the wire, it does not need to be serializable. [#99] * feat: make SourceDetails and StreamType serializable - fields of these classes are accessed and returned from functions, which need to be transferred over the wire to different nodes. Hence, the classes themselves also need to be serialized. Otherwise, a java not serializable exception is thrown by Flink. [#99] * feat: fix checkstyle formatting issues [#99] * feat: fix checkstyle formatting errors [#99] * feat: return UNBOUNDED/KAFKA as default SourceDetails when not specified - this is to maintain backward compatibility of already running daggers which use unbounded kafka as a source [#99] * feat: return StreamType instead of Stream from StreamsFactory - disable sending of telemetry from StreamsFactory as it is deemed to be not useful after discussion. - use stream types to build the Flink DataStream in StreamManager [#99] * feat: delete Stream, StreamBuilder and its implementations - stream creation will now happen using StreamType and its implementations [#99] * feat: delete SourceFactory,DeserializerFactory and StreamMetrics - source and deserializer are now created together from StreamType implementations [#99] * feat: delete Mockito extension - it was used for mocking default case of switch in some tests of DeserializerFactory, which has been removed - see commit 91afc8f for details [#99] * feat: rename KafkaSourceJsonSchema to KafkaSourceJsonSchemaStreamType - update usages [#99] * feat: rename KafkaSourceProtoSchema to KafkaSourceProtoSchemaStreamType - update usages [#99] * feat: rename ParquetSourceProtoSchema to ParquetSourceProtoSchemaStreamType - update usages [#99] * feat: throw runtime exception for unsupported split assigner [#99] * feat: return default timestamp when not set or present in simple group - this is needed as otherwise every new addition of timestamp fields to the proto will fail the dagger job and break backward compatibility [#99] * feat: delete unused methods from SimpleGroupValidation [#99] * feat: inject file path regex into chronology split assigner from stream config - add new stream config SOURCE_PARQUET_CHRONOLOGICAL_FILE_PATH_REGEX [#99] * feat: edit the exception message for regex no match in chronology split assigner - print the configured pattern as well for context [#99] * Revert "feat: edit the exception message for regex no match in chronology split assigner" This reverts commit f6cf116. * Revert "feat: inject file path regex into chronology split assigner from stream config" This reverts commit 539dbd0. * feat: rename functions of ProtoHandler as per review - rename transformForKafka to transformToProtoBuilder - rename transformFromKafka to transformFromProto [#99] * feat: create row from millis inline instead of calling RowFactory - delete unnecessary methods [#99] * feat: remove unused imports - this fixes checkstyle formatting issue [#99] * feat: add support for deprecated FlinkKafkaConsumer - KafkaSource still has a few unsolved issues which cause issues in production, such as this https://www.mail-archive.com/[email protected]/msg46602.html - in order to maintain backward compatibility, support for FlinkKafkaConsumer is added and will be used as the default source for all dagger jobs [#99] * test: add tests for StreamsFactory [#99] * test: add tests for StreamType [#99] * test: add tests for DaggerDeserializerFactory [#99] * test: add tests for DaggerSourceFactory [#99] * test: add tests for JsonDeserializerProvider [#99] * test: add tests for ProtoDeserializerProvider [#99] * test: add tests for SimpleGroupDeserializerProvider [#99] * test: add tests for KafkaDaggerSource -

Dagger will soon have a new data source for Parquet files. For deserialization of records, it will continue to use
dagger-commonmodule and the handler classes within.Currently, the package names have keywords like
protoandprotohandlerwhich are kind of misleading as the same handler classes will have methods to do parsing for bothProtobufobjects as well asSimpleGroupobjects.Hence, there is a need to refactor some of these package names and classes inside the
dagger-commonmodule to better reflect its responsibility.This issue is meant to do that. No functional change is required. This will only be a refactor.
