Andy Seaborne commented on JENA-782:
------------------------------------
commit 4a45e361739bd2c8e2df56a9bc02015728b011bf
This merges into master the changes for configurable TDB databases.
Not yet completed: Changes to application API TDBFactory. Currently, an
application needs to create database using StoreConnection, then get it via
TDBFactory. This is only to limit the visibility of changes pending detailed
testing and usage in TDB and Fuseki. By default, the system should behave
exactly as it did before.
> Provide configurability of TDB in database setup

> Key: JENA-782
> URL: https://issues.apache.org/jira/browse/JENA-782
> Project: Apache Jena
> Issue Type: Improvement
> Components: TDB
> Affects Versions: Jena 2.12.0
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
>
> Creating TDB databases and attaching to existsing ones is quite fixed
> currently. Any internal paramaters are quite difficult to manipulate and
> they are globals.
> Configurability of TDB databases has two dimensions:
> # Initial setup (e.g. block size)
> # Per JVM (e.g. cache sizes).
> (The file mode is actually a per JVM feature but should probably be regarded
> as an initial setup feature only.)
> With configurability, TDB and Fuseki could be scaled down for small databases
> and for many small databases in one JVM.
