[Wikidata-bugs] [Maniphest] T290240: Evaluate whether RDF Delta is a good idea to have in the backend

2022-02-07 Thread AndySeaborne
AndySeaborne added a comment.


  Zookeeper keeps the index, the HA storage is usually in something with an S3 
<https://phabricator.wikimedia.org/S3> interface to use as a blob store.

  @nguyenm9 - RDF Delta adds the replication of updates across a number of 
stores (Apache jena Fuseki).

AndySeaborne added a comment.


  @AWesterinen - Fuseki is part of Jena. Most of the subsystems have informal 
names. People refer to "Jena" or "Fuseki" interchangeably and the context is 
the task they are doing. Being more specific on naming didn't catch on.

[Wikidata-bugs] [Maniphest] T299460: Evaluate Apache Jena

2022-01-22 Thread AndySeaborne
AndySeaborne added a comment.


  All - I'm sorry that this sub-task is being redirected to be about Virtuoso. 
This would be better moved to the Virtuoso task.
  
  Apache Jena releases a single software product. TDB is the only persistence 
layer for Apache Jena that comes from the Apache Jena project.
  
  The link @TallTed gives is to Virtuoso-specific documentation. The software 
does not come from the Apache Jena project.
  
  TDB is the _internal_ name for a component which is the B+Trees. TDB2 is the 
current generation of that component.
  
  SPARQL is important aspect for Wikidata and the first code example shows the 
bypass of Apache Jena SPARQL execution and only thin use of the Java API.
  
  ---
  
  @TallTed: The examples on the page do not describe Virtuoso used as a "low 
level storage choice" for SPARQL execution; it shows complete bypass of the 
Jena.
  
  It should be on the task for evaluating Virtuoso because it is what OpenLink 
is providing.  It is 5% Jena (API layer) and 95% Virtuoso.  All performance and 
data scale characteristics are down to Virtuoso.
  
  I do not understand why WikiData usage would want to bypass the Virtuoso 
triplestore HTTP interface but if you want that considered, it would be better 
as part of the Virtuoso evaluation. It can be compared to the same approach 
with other code APIs accessing Virtuoso.
  
  The diagram, at best, it might be said to relate to the design of the 
research prototype Jena1 (over 15 years ago) many years before Jena became 
Apache Jena. SPARQL didn't exist for that architecture which predates W3C work 
on SPARQL.
  
  - SPARQL evaluation does not go through the Model API.
  - Apache Jena does not provide storage in SQL databases anymore.
  - TDB does not store models.
  - TDB isn't even mentioned on the diagram.
  
  The page you link to talks about Jena 2.6, which is not an Apache release, 
and Jena 2.10.0 is 2013-02-24 - during the transition to Apache Jena.
  
  Virtuoso can provide fine-grained access with VirtGraph but that is not how 
TDB fits into Jena.
  Using VirtGraph might get Virtuoso users SHACL/ShEx support but that isn't 
the focus for WikiData as I understand it.
  
  If you want to discuss the general integration of Virtuoso and Jena, then 
let's take that to the Jena mailing lists.

AndySeaborne added a comment.


  Hi @dcausse - TDB2 on it's own doesn't provide SPARQL nor any of the other 
features. TDB2 is just one low level storage choice - it's not a standalone 
thing. I hope you find the description clearer now.
  
  The project has had other 3rd party organisations presenting their own naming 
and architecture descriptions of Jena so I just wanted to be clear here.
  
  If there is anything else I can help with - please do ask.

  Are there any timescale/triple scale goals currently being stated?
  
  With a baseline minimum 
<https://wikitech.wikimedia.org/wiki/Wikidata_Query_Service/ScalingStrategy> of 
1B triples/3 months, and assuming a 5-10 year goal for any choice, that gets to 
36B-56B triples minimum and it could easily exceed that.

AndySeaborne created this task.
AndySeaborne added projects: Wikidata-Query-Service, Epic, Wikidata, 
MediaWiki-Stakeholders-Group.

TASK DESCRIPTION
  Apache Jena https://jena.apache.org/ provides SPARQL 1.1, SHACL (core and 
SPARQL), ShEx, and RDF-star.
  
  Jena has been reported to 
[https://lists.apache.org/thread/wqr8vg43v2kd3ofrncn1tk9lxy078p83 load Wikidata 
(20211222_latest-all.nt.gz)] (16.7 billion triples at 44.8k triples/second in 
103h 45m 15s).
  
  Jena has been reported to 
[https://lists.apache.org/thread/wvtr4ohjwm5tm9z77q702fbsz2o7gbp2 load Wikidata 
Truthy (2021-12)] (6.6 billion triples in 40 hours, at 46k
  triples/second).
  
  Jena has various extension mechanism for incorporating extensions, including
  overloading the SERVICE keyword.
  
  Jena might provide a way for users to load the data, or a focused subset of 
the
  data, for local use thereby potentially offloading the central SPARQL service.

  We can be objective about feature support.
  
  The working group tests for SPARQL 1.1 (updated for RDF 1.1) are maintained 
by the community: https://w3c.github.io/rdf-tests/.
  
  They have reasonable coverage of features.
  
  In addition, engines can an do support more of XPath and XQuery Functions and 
Operators 3.1 than the minimal required the the SPARQL REC.
