What are the proper settings in the crawler-conf.yaml
(and elsewhere, if needed) for the info from the following meta-tag:
ANSWER
Answered 2019-Jun-11 at 13:00Here's what I sorted out. the 'parse' that is referenced in the 'parse.title' in the quoted code above is a reference to (edit: the key of the meta tag, which is then retrieved by) a custom entry under the top class in the src/main/resources/parsefilters.json
file. I went in there and added a
"parse.college": "//META[@name=\"college\"]/@content"
line underneath the ones that were there but still within the top class.
I then changed the reference to college under indexer.md.mapping
to read - parse.college=college
and rebuilt the crawler and ran it. It then started properly grabbing the tag and sending it to a
college
field in the index.
QUESTION
Our university web system has roughly 1200 sites, comprising a couple million pages. We have Stormcrawler installed and configured on a machine that has apache running locally, with a mapped drive to the file system for the web environment. This means that we can have Stormcrawler crawl as fast as it wants with no network traffic being generated at all, and no effect on the public web presence. We have the Tika parser running to index .doc, .pdf, etc.
- All websites are under the *.example.com domain.
- We have a single Elasticsearch instance running with plenty of CPU, Memory and Disk.
- The index-index has 4 shards.
- The metrics index has 1 shard.
- The status index has 10 shards.
With all of that in mind, what is the optimal crawling configuration we can do to get the crawler to ignore politeness and blast it's way through the local web environment and crawl everything as fast as possible?
Here are the current settings in the es-crawler.flux regarding spouts and bolts:
...ANSWER
Answered 2019-Mar-22 at 10:43ok, so you are in fact dealing with a low number of distinct hostnames. You could have it all on a single ES shard with a single ES spout really. The main point is that the fetcher will be enforcing politeness based on the hostname and the crawl will be relatively slow. You probably don't need more than one instance of the FetcherBolt either.
Since you are crawling your own sites, you could be more aggressive with the crawler and allow multiple fetch threads to pull from the same hostname concurrently, try setting
fetcher.threads.per.queue: 25
and also retrieve more URLs from each query to ES with
es.status.max.urls.per.bucket: 200
that should make your crawl a lot faster.
BTW: could you please drop me an email if you're OK being listed in https://github.com/DigitalPebble/storm-crawler/wiki/Powered-By ?
NOTE to other readers: this is advisable only if you are crawling your own sites. Being aggressive to third-party sites is impolite and improductive as you risk to be blacklisted.
