Steem Data Services (SDS) / Upcoming Update Info / Version 0.1.7a

Version Details

---

SDS will be updated to version 0.1.7a within the next few days. Currently re-indexing of all blocks is already running at the sds0 endpoint (developer requests going to sds0 are automatically proxied to sds1 in the meantime).

Here are some of the most important new features and changes in this version:

• Field word_count in all feed lists
  This will allow us to get the word count for each post directly from the result without the need of rendering the Markdown and stripping Markup tags from the body. It is not perfect yet, but will be optimized over the coming weeks.

• Feeds by hot/trending score without whale votes
  The newly added trending score algorithm allows to get hot/trending posts without whale voters. It will enable us to retrieve lists of trending posts with almost all 'up-boted' posts removed.

• Feeds by interaction score
  The new interaction score algorithm allows to get trending posts by user interaction. Instead at the voted rshares (payout) of each post, it only looks at author and reader interaction (more details will follow in an extra post at some point).
   
  The algorithm will be optimized over time (@realrobinhood will contain a small overview in his coming daily stats reports, where the results can be discussed to further improve the whole thing).

• Field image_url deprecated
  The field image_url in the feeds_api's results will be removed (returned empty for now and removed completely in one of the next updates), because it can't be reliably filled on the server side. For example, getting preview images for videos should always be done by the client, because it depends on the used device's screen size which resolution should be loaded (mobile devices should load a smaller preview).
   
  Some video platforms (like vimeo) don't even allow loading preview images without making an extra request to their API. Additionally, not all front-ends will fill the image field in json_metadata correctly, so it does not make sense to have the logic implemented on two ends. The viewer app needs to be able to get the image from the body anyway. Therefore I will remove this redundant field from the API.

• Improved getSteemProps API method
  As many developers requested to be able to retrieve a bundle of most important Steem properties with one request, I added the following API method (ready to be used on sds0, sds1 will be updated in a day or so): https://sds0.steemworld.org/steem_requests_api/getSteemProps
   
  The result also contains a field steem_per_share that provides the current STEEM per VEST value. Currently the data is updated every minute, but I will change this to be almost in sync with the blockchain. I also added a few more fields like the current market ticker data. If you should miss any property in there, just let me know ;)
