v7.0.2

This is a patch release that fixes the following issue:

• Issue #394 : Resource leak in FileRecordReader

This release also includes some minor backward-compatible dependency updates:

• jackson-databind: 2.12.0 -> 2.12.2
• yasson: 1.0.7 -> 1.0.8
• univocity-parsers: 2.9.0 ->2.9.1
• xstream: 1.4.15 -> 1.4.16
• spring: 5.3.2 -> 5.3.4
• hibernate: 5.4.26.Final -> 5.4.29.Final

v7.0.1

This is a patch release that fixes the following issue:

• Issue #393 : Errors in reader/writer open/close methods are not handled

This release also includes some minor backward-compatible dependency updates:

• jackson-databind: 2.11.2 -> 2.12.0
• univocity-parsers: 2.8.4 ->2.9.0
• xstream: 1.4.12 -> 1.4.15
• yamlbeans: 1.13 -> 1.15
• spring: 5.2.9.RELEASE -> 5.3.2
• hibernate: 5.4.21.Final -> 5.4.26.Final
• hibernate-validator: 6.1.5.Final -> 6.1.7.Final

v7.0.0

This release is a major version as it requires Java 11 or above. The main theme for this release is API type safety. There are no new features in this version except updating all APIs to be generic:

• RecordReader (and its listener): 7ed62a5
• Batch (and its listener): ba60977
• RecordWriter (and its listener): d437aa5
• RecordProcessor (and its listener / sub interfaces): 279ed29
• Predicate: 063fcc5
• JobBuilder: 6929936

These changes require updating job definitions to use generics for input/output types in order to enforce the correctness and coherence of expected types between the record reader and writer (More details about this in issue #388).

Migration guide from v6.1 to v7.0

1. Job definition updates

The most notable change required by this release is regarding job definitions:

--Job job = new JobBuilder() // v6
++Job job = new JobBuilder<String, Tweet>() // v7
                 // define batch components
                .build();

Specifying input/output types is not mandatory, but not doing so will lead to a raw type usage warning.

2. RecordProcessor generic types updates

Another important change has been introduced in this release about the generic type of RecordProcessor. In v6, the generic types of RecordProcessor were the types of input/output records. In v7, generic types now represent the type of the payload of input/output records:

--public interface RecordProcessor<I extends Record, O extends Record> {  // v6
--      O processRecord(I record) throws Exception;
--}
++public interface RecordProcessor<I, O> { // v7
++     Record<O> processRecord(Record<I> record) throws Exception;  
++}

This change has a direct impact on all interfaces extending RecordProcessor (like RecordFilter, RecordMapper, RecordMarshaller and RecordValidator) and their corresponding implementations.

3. Other API updates

Any usage of the aforementioned APIs (RecordReader, RecordWriter, Batch, etc) and their associated listeners should be updated to use generics where appropriate.

4. Deprecated APIs removal

All deprecated APIs in v6.0 and v6.1 have been removed in this major release. The suggested replacement (if any) should be found in the Javdoc of the deprecated API.

v6.1.0

This is a minor release which can be used as a drop-in replacement for v6.0.0. Here are the major changes:

New Features and enhancements

• Issue #368: Add RetryableRecordProcessor implementation
• Issue #381: Add default methods in record reader/writer interfaces

Bug fixes

• Issue #372: BeanPropertiesPreparedStatementProvider is failing to prepare statement if bean properties has null value

Deprecations

• Issue #380: Deprecate the static factory method JobBuilder#aNewJob
• Issue #379: Deprecate ContentBasedBlockingQueueRecordWriterBuilder

v6.0.0

This major release marks a new generation of the framework which is now based on Java 8. It has been an opportunity to improve the framework internals as well as some public APIs. All deprecated APIs in v5.3 and before have been removed. Some APIs have changed in a non-backward compatible way to fix a couple of minor design inconsistencies introduced in the v5 line.

The root package has been updated from org.easybatch to org.jeasy.batch for consistency with other Jeasy projects. Artifact IDs have also been changed to match the same naming pattern as other projects. Please refer to the migration guide below for more details.

As you will see in the migration guide, many APIs have been deprecated in previous versions and are now completely removed. As Antoine de Saint-Exupery said:

"Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away"

I believe with this release, there is no much more to take away from Easy Batch, but this does not make it perfect! That said, I am very happy and proud to see some serious companies using it in production as well as encouraging feedback from the community. So I would like to thank all contributors who helped making this release possible! Thank you all for your time and efforts! You are awesome 👍

In addition to dependencies and documentation updates, here are the major highlights for v6.0:

New features

• Issue #261: Add support for JSON mapping with Yasson (JSON-B RI)
• Issue #311: Add support for Java 8 date/time classes
• Issue #353: Add converters for Java 8 date/time types
• Issue #361: Make JobExecutor implement java.lang.AutoCloseable
• Issue #363: Add batch scanning feature
• Issue #366: Add formatting option in BeanFieldExtractor

Enhancements

• Issue #351: FileRecordWriter should not throw an Exception at construction time
• Issue #355: Remove system properties from JobReport#toString
• Issue #356: Improve job duration formatting
• Issue #357: Show job duration in the logs
• Issue #364: Add default methods in listener interfaces

Bug fixes

• Issue #352: XmlRecordReader should close the input stream
• Issue #365: Incorrect fixed length record marshalling

New tutorials

• Reading data from a REST endpoint
• Writing a dynamic header/footer to an output file
• Skipping bad records with batch scanning on write failure

Breaking changes

• All usages of java.io.File (namely in constructors of all file based record readers/writers) were deprecated in v5.3 and have been replaced with java.nio.file.Path in v6
• Quartz support was deprecated in v5.3 and has been removed in v6. The entire module easybatch-quartz has been removed in v6. This module used to provide two classes that act as a bridge between Easy Batch APIs and Quartz APIs. Those two classes (EasyBatchJob and EasyBatchJobFactory) can now be copied from the Quartz tutorial.
• MongoDB support has been dropped (Issue #354). Please note that this decision was made after releasing v5.3, hence you will not find any @Deprecated annotations on classes of this module in the v5.3 release. Sorry for any inconvenience!
• JobListener#beforeJobStart and JobListener#afterJobEnd have been renamed to JobListener#beforeJob and JobListener#afterJob (Issue #362)
• Jms reader/writer now work with a JMS Destination instead of Queue to support Topics as well (Issue #359)
• The constructor of JmsMessageTransformer now accepts a javax.jms.Session instead of javax.jms.QueueSession to support both queue and topic sessions (Issue #360)
• The JmsRecordReader now returns null based on a timeout and not a JmsPoisonMessage anymore (because JmsPoisonMessage has been removed, see "Removed APIs" section of the migration guide)
• The BlockingQueueRecordReader now returns null based on a timeout and not a PoisonRecord anymore (because PoisonRecord has been removed, see "Removed APIs" section of the migration guide)
• All EIP related APIs (ContentBasedBlockingQueueRecordWriter, ContentBasedBlockingQueueRecordWriterBuilder, DefaultPredicate, Predicate, RandomBlockingQueueRecordWriter, RoundRobinBlockingQueueRecordWriter) and their JMS equivalent were moved to a new extension module called easy-batch-integration

Migration guide from v5.3 to v6.0

Although care has been taken to document all changes in details, a thing or two could have been missed (in which case, apologies upfront).

Migration guide

JobBuilder

Methods deprecated in v4.2 have been removed in v5:

• JobBuilder#skip(long)
• JobBuilder#limit(long)
• JobBuilder#timeout(long) and JobBuilder#timeout(long, TimeUnit)
• JobBuilder#silentMode(boolean)
• JobBuilder#strictMode(boolean)
• JobBuilder#jmxMode(boolean)
• JobBuilder#call()

The keepAlive parameter has been removed since resource handling is now done by the framework ( issue #221 ). Hence the following methods have been removed from JobBuilder:

• JobBuilder#reader(RecordReader recordReader, boolean keepAlive)
• JobBuilder#reader(RecordReader recordReader, boolean keepAlive, RetryPolicy retryPolicy)

The "Retry Read" feature is now done with a decorator of RecordReader (issue #224 ). Hence the method JobBuilder#reader(RecordReader recordReader, RetryPolicy retryPolicy) has been removed

The RecordDispatcher API has been removed. Hence, the method JobBuilder#dispatcher(RecordDispatcher recordDispatcher) has been removed

JobExecutor

• The method org.easybatch.core.job.JobExecutor.execute is no more static, you need to create a JobExecutor instance to execute jobs
• Job executors must be shutdown explicitly

Resource handling & transaction management

• The constructors of JdbcRecordReader/JdbcRecordWriter now take a JDBC DataSource as argument instead of a Connection and the JdbcConnectionListener/JdbcTransactionListener have been removed
• The constructors of JpaRecordReader/JpaRecordWriter now take a EntityManagerFactory as argument instead of a EntityManager and the JpaEntityManagerListener/JpaTransactionListener have been removed
• The constructors of HibernateRecordReader/HibernateRecordWriter now take a SessionFactory as argument instead of a Session and the HibernateSessionListener/HibernateTransactionListener have been removed

Moved APIs

• org.easybatch.core.dispatcher.Predicate has moved to org.easybatch.core.writer.Predicate
• org.easybatch.core.dispatcher.DefaultPredicate has moved to org.easybatch.core.writer.DefaultPredicate
• org.easybatch.core.dispatcher.PoisonRecordBroadcaster has moved to org.easybatch.core.listener.PoisonRecordBroadcaster

Removed APIs

The Batch class is no more a Record. Instead, it now contains a list of records. Hence, all interfaces and implementations related to the previous inconsistent Batch API have been removed: BatchReader, BatchFilter, BatchMapper, BatchProcessor, BatchMarshaller, BatchValidator and BatchWriter.

The "record dispatcher" concept has been removed. All dispatchers have been transformed into writers:

• BroadcastRecordDispatcher -> BlockingQueueRecordWriter
• ContentBasedRecordDispatcher -> ContentBasedBlockingQueueRecordWriter
• ContentBasedRecordDispatcherBuilder -> ContentBasedBlockingQueueRecordWriterBuilder
• RoundRobinRecordDispatcher -> RoundRobinBlockingQueueRecordWriter
• RandomRecordDispatcher -> RandomBlockingQueueRecordWriter
• BroadcastJmsRecordDispatcher -> BroadcastJmsQueueRecordWriter
• ContentBasedJmsRecordDispatcher -> ContentBasedJmsQueueRecordWriter
• ContentBasedJmsRecordDispatcherBuilder -> ContentBasedJmsQueueRecordWriterBuilder
• RandomJmsRecordDispatcher -> RandomJmsQueueRecordWriter
• RoundRobinJmsRecordDispatcher -> RoundRobinJmsQueueRecordWriter

Exception handling have been simplified, the following exceptions have been removed:

• org.easybatch.core.reader.RecordReaderOpeningException
• org.easybatch.core.reader.RecordReaderClosingException
• org.easybatch.core.reader.RecordReadingException
• org.easybatch.core.processor.RecordProcessingException
• org.easybatch.core.dispatcher.RecordDispatchingException
• org.easybatch.core.field.RecordFieldExtractionException
• org.easybatch.core.mapper.RecordMappingException
• org.easybatch.core.marshaller.RecordMarshallingException
• org.easybatch.core.validator.RecordValidationException
• org.easybatch.core.writer.RecordWritingException

ApacheCommonCsvRecord was removed. This is redundant with StringRecord.
ApacheCommonCsvRecordReader was removed. This is redundant with FlatFileRecordReader.

Other changes

• org.easybatch.core.processor.ComputationalRecordProcessor deprecated in v4.2 has been removed
• JobResult deprecated in v4.2 has been removed from JobReport, this is related to the removal of ComputationalRecordProcessor
• All constructors in XmlWrapperTagWriter now take a File instead of FileWriter, this is due to a resource leak
• BeanValidationRecordValidator is no more parametrized type
• Predicate is no more a parametrized type
• BlockingQueueRecordReader is no more a parametrized type
