Technologies for selectively streaming video based on mapping buffer data to download rates. The technologies can include sampling download rates of a video player prior to or during downloading of a first video segment to the video player. The technologies can include determining a range of download rates of the video player based at least on the sampled download rates. The technologies can include determining an amount of accumulated video data in a buffer of the video player immediately prior to or during the downloading of the first video segment. Also, the technologies can include mapping the determined amount of accumulated video data to a download rate within the determined range of download rates using a mapping function, and determining a second video segment quality for a second video segment based at least on the mapped download rate.

Selective streaming of video segments based on buffer data and download rate range

One or more computing devices, systems, and/or methods for automated materialized view table generation and maintenance are provided. A log, comprising queries and latencies of processing the queries, is evaluated to identify a list of combinations of fields that occur greater than a threshold frequency and/or occur in queries having latencies greater than a threshold latency. A materialized view generation script is executed against a main database to generate a materialized view table associated with a combination of one or more fields from the list. A middleware component is configured to selectively direct a query to the main database or to the materialized view table based upon whether the materialized view table comprises preliminary query results for fields specified by the query.
