Alan Orth	560fa6056d	README.md: Remove batch inserts from TODO	2018-09-26 23:25:35 +03:00
Alan Orth	385a34e5d0	indexer.py: Use psycopg2's execute_values to batch inserts ... Batch inserts are much faster than a series of individual inserts because they drastically reduce the overhead caused by round-trip communication with the server. My tests in development confirm: - cursor.execute(): 19 seconds - execute_values(): 14 seconds I'm currently only working with 4,500 rows, but I will experiment with larger data sets, as well as larger batches. For example, on the PostgreSQL mailing list a user reports doing 10,000 rows with a page size of 100.

Alan Orth	e604d8ca81	indexer.py: Major refactor ... Basically Solr's numFound has nothing to do with the actual number of distinct facets that are returned. You need to use Solr's stats component to get the number of distinct facets, aka countDistinct. This is apparently deprecated in newer Solr versions, but we're on version 4.10 and it works there. Also, I realized that there is no need to return facets for items without any views or downloads. Using facet.mincount=1 reduces the result set size and also means we can store less data in the data- base. The API returns HTTP 404 Not Found if an item is not in the database anyways. I can't figure it out exactly, but there is some weird issue with Solr's facet results when you don't use facet.mincount=1. For some reason you get tons of results with an id that doesn't even exist in the document database, let alone as an actual DSpace item! See: https://lucene.apache.org/solr/guide/6_6/the-stats-component.html	2018-09-26 02:41:10 +03:00

Alan Orth	806d63137f	requirements.txt: Use kazoo 2.5.0 ... SolrClient 0.2.1 currently depends on kazoo 2.2.1, but there is an issue with Python 3.7 in kazoo <= 2.5.0. Kazoo 2.5.0 fixes the is- sue with Python 3.7, and for my limited usage of SolrClient it se- ems to work fine.
