====== goals:

• spec compliant, portable batching implementation for Java SE and EE, and are also pluggable into other Java EE 7 compliant application servers.

• certain QoS features for EE environment (integration with admin console, cli for easy management of batch jobs)

=============== Current Status:

The following high-level features and components are implemented:

• parse and load job.xml and batch.xml

• scan annotations to identify batch artifacts

• injection of batch contexts and batch properties

• resolve property reference with batch expression language and detect cyclic ref

• resolve inheritance of job and step and detect cyclic inheritance (deferred in spec to next release)

• overall job execution logic and detect cyclic transition

• batchlet step execution logic

• step metrics api

• flow execution logic

• split execution logic

• decision transitioning logic

• initial support for listener invocations

• unit tests and end-to-end test apps

• batch api spec project (https://github.com/jboss/jboss-batch-api_spec)

• replaced jaxb with stax

• replaced scanotation with CDI

• created spi to abstract out environment-dependent services (transaction, concurrency, batch configuration, etc)

High-level TODO:

• Run CTS batch tests
• integrate into WildFly
• implement JBeret SPI for Java EE as part of wildfly/batch module

=================== Tentative schedule:

EE 7 is currently scheduled to release in 2013 Q2 (can be as late as 2013-06-30). AS 8 schedule is TBD. The following is just a rough estimate, and the actual schedule will change depending on the JSR 352 spec status, implementation progress, and any changes in EE and AS 8 schedules.

Milestones	Dates	Focus	Deliverable
M1	2013-01 -- 2013-03	core spec requirements	Alpha release
M2	2013-04 -- 2013-06	advanced EE features and AS integration tasks	Beta release
M3	2013-07 -- 2013-09	Integration with external tools and frameworks, and bug fixes	Feature Complete, Soft Code Freeze
M4	2013-10 -- 2013-11	continue bug fixes	GA

major tasks:

• core requirements
  • configuration
    • annotation processing * xml parsing for job.xml and batch.xml, jaxb? * annotation and xml meta data merging * JSL inheritence merging * our product-specific configuration * in EE, part of domain.xml/standalone.xml * in SE, a separate xml file?
  • job execution
    • implement various batch context types
    • implement various batch listeners
    • checkpoint
    • transaction integration
    • parallel
      • in EE, leverage JSR 236 (Concurrency Utils for EE). What's our implementatioin? JBoss Threads?
      • in SE, java.util.concurrent, or some JBoss concurrency library
    • basic reader, writers
      • xml, csv, excel, db
  • job management, monitoring
    • interface with DMR management model
    • job repository
      • various job repository impls, such as file, db, xml
      • application-scoped or global?
• EE extra features, EE integration layer
  • need a integration module in AS
  • integrate with
    • admin console (view and manage jobs)
    • cli (ditto)
    • deploy/undeploy, load/unload
    • management
    • security (who can access and modify job repository)
    • cluster support
      • remote chunk execution
      • remote concurrent step execution
      • how to distribute jobs across cluster
• extensions to hook up with external tools, 3rd party frameworks
  • Jenkins
  • Quartz

work by other teams (need to coordinate):

• tools update to support batch apps
• admin console
• CLI
• jboss-specs update (https://github.com/jboss/jboss-javaee-specs)
• quickstart
• EAP dev guide, admin guide
• QE, include in testing
• Arquillian update?
• PM, include in product requirements
• JIRA, BZ, add batch category
