Crawl RSS Feeds from iTunes

I currently have a script that parses the iTunes API and puts the data into ElasticSearch and Cassandra databases. It crawls the RSS feeds twice per day. It checks iTunes for new Podcasts every day as well. Here is an example of an RSS feed that it parses. [login to view URL] So there are Podcasts which are like audio shows. And then each Podcast has multiple episodes. In other words, each Podcast has one RSS feed and each RSS feed shows the episodes for that podcast sorted by newest release date first. The current developer of the script is not very responsive to making changes. So your job is to 1 - There are some parse errors for some of the podcast rss feeds. 2 - We are missing a lot of podcasts from iTunes. We can get some of those from another websites API. 3 - Setup data for each podcast regarding how often they release new episodes. We can determine their frequency by just looking at the RSS feed and storing the frequency in the database. For example for those that have a frequency of once per day or multiple times per week we should crawl every hour of the day or every few hours. For those that are once per week we should crawl maybe 2 - 4 times per day etc...If only once per month then we only crawl once per day. I will give you the code so you can understand how it currently works. The code is written in python. You can rewrite it in any other language that makes sense. It does not have to be Python. So we need a new system to organize the crawling so we can know the status. So we know if certain RSS feeds had errors and we were not able to update. Then we need to find out the reason. If the reason is acceptable then we can make not of that in the database. The updates are added to ElasticSearch and Cassandra. Thank you
