Hello All,
Are there any articles on performance tuning of TDB datasets?
There aren't many tuning parameters for TDB - for example, there are
three indexes on triples so any order of lookup can be found.
This is by-design - so you spend time on your problem, not on the system.
I’m loading 5.5 million rows into TDB and i will be searching the
dataset based on instances, properties and partial texts
5.5 million isn't very large - the indexes will probably fit completely
in memory so.
Running on an SSD is good when updates are significant.
Just make sure there is enough RAM - look at the index sizes.
If i want to create a lucene index based on "base uri” and text
fields of the data , how do i go about doing that?
See
http://jena.apache.org/documentation/query/text-query.html
for eg
“http://example.com/class#instance1”
Thanks
