-----------------------------------
Summary: Provide transaction promotion
Key: JENA-1223
URL: https://issues.apache.org/jira/browse/JENA-1223
Project: Apache Jena
Issue Type: Improvement
Components: TDB
Affects Versions: Jena 3.1.0
Reporter: Andy Seaborne
This JIRA is to add the ability for a read transaction to promote to a write
transaction.
API changes are necessary to expose this feature properly and uniformly.
PR #161 provides the machinery for TDB. To avoid general API changes outside
TDB, this happens automatically in {{DatasetGraphTransaction.getW()}} if
enabled (by default it isn't, the PR makes no change to behaviour of TDB by
default). It needs to be enabled with {{DatasetGraphTransaction.promotion =
true}}.
This leads towards a general {{begin()}} for transactions.
This JIRA is cover discussion on the API and record changes to the subsystems.
