TASK DESCRIPTION
When updater runs the update, it generates SPARQL like this:
```
# Clear out of date statements about statements
DELETE {
?s ?p ?o .
}
WHERE {
<http://test.wikidata.org/entity/Q1229> ?statementPred ?s .
FILTER( STRSTARTS(STR(?s), "http://test.wikidata.org/entity/statement/";) ) .
?s ?p ?o .
FILTER NOT EXISTS {
VALUES ( ?s ?p ?o ) {
.... statements ...
}
}
}
```
However, in the list of statements, all statements from the dump are
included, even though only statements starting with
`<http://test.wikidata.org/entity/Q1229>` are relevant. We should split the
statements and only send the relevant ones in the query, this would both speed
up the queries and reduce the load on the server.
