Home. Redis (data store) Supported languages[edit] Data models[edit] The type of a value determines what operations (called commands) are available for the value itself. Redis supports high-level, atomic, server-side operations like intersection, union, and difference between sets and sorting of lists, sets and sorted sets. Persistence[edit] By default, Redis syncs data to the disk at least every 2 seconds, with more or less robust options available if needed. In the case of a complete system failure on default settings, only a few seconds of data would be lost.[9] Replication[edit] Redis supports master-slave replication. Performance[edit] Clustering[edit] Cloud deployment[edit] Redis is commonly deployed on IaaS or PaaS platforms like Amazon Web Services, Rackspace or Heroku.
On IaaS platforms, it is possible to deploy Redis by uploading a virtual machine image, with Redis installed, to a cloud machine instance.

Google web search results can be limited by timeframe using the “search options” link on every page, but one startup company CEO discovered today that searches can also be limited to results indexed minutes or seconds ago by making a simple change to the search results page URL. Startup search engine Omgili’s CEO Ran Geva wrote on his company blog today that time-limited search results pages include a parameter called QDR – perhaps standing for Query Date Range. You can change the number following the letters qdr and change the timeframe for your search. By default when you click on “search options” and limit a search to the last day, the qdr appears as “d.” Change that to “n” and you’ll be limited to results from the last minute, to “n10” and you’ll see results discovered in the last 10 minutes – or “s30” to see results from the last 30 seconds.
It couldn’t be simpler. Here’s a sample search for Portland Oregon Coffee with the search options already turned on.
