Features

Failover Mode for P6 Core

Starting this release, two P6 Core nodes can target the same database within a single instance in “active/passive” mode for failover. More information can be found here.

P6 Sync Endpoints & Documentation

P6 Sync was dramatically enhanced and is nearing the release of a 1.0.0 version. You can find the documentation of P6 Sync here.

Improvements

Web3j Upgraded

Support for Ethereum was revamped and the underlying Web3j library was upgraded from 3.6.0 to 4.3.1.

Swagger Upgraded

Swagger support was upgraded to support the latest Open API spec and work with the latest version of Swagger UI. Therefore, the Swagger UI no longer ships with P6 Core. This effort also included upgrading to the latest version of Jetty.

Transaction DSL Simplified

To reduce the learning curve for newcomers, terms such as project were replaced by saveAndValidate. Also, the default data model is no longer MessageInfo but TransactionInfo.

New JDBC Connection Pool

For better performance and scalability, P6 Core switched from C3P0 to HikariCP.

p6 DSL Binding Introduced

To avoid clashes between local variable names and DSL bindings, an all encompassing DSL binding p6 was introduced. Hence, you should prefix all your DSL calls with p6.

Technical Changes

Cluster and Concept Renamed, Item Table Partitioned

The notion of cluster was renamed dataPartition and concept was renamed dataType to reduce the learning curve for newcomers.

In the database, the following tables were deleted:

  • configurationinfo
  • datacluster
  • datamodel

The item table was partitioned into 3 new tables:

  • transaction that contains all transactions and workflows of all types.
  • table_data that contains all reference table data.
  • log that contains logs.

WFWorkItem Renamed to WorflowTask

This renaming applies everywhere.

Support for Old b2box Users Removed

The underlying B2BoxUserImpl class was deleted.

Bug Fixes

This release ports all bug fixes from the 5.24.X branch.
