The O2O system should be based on the O2O of the fans rather than the o2o! of the products. Now the mobile phone has entered the so-called 020 era, the most typical is Wang O2o, he wants to through the offline integration of the customer's aggregation, in turn to increase his shopping volume, through the experience to create his more customer aggregation. Is this right? But I think this way of thinking should still stay in the electricity quotient 1.0 times, or he forgot the entire mobile Electricity Business Foundation, the mobile electricity merchant most important foundation, the life is bigger than the business. So the essence of O2O is not the O2O of the product.

A small-file-based memory cloud storage optimization Strategy Yu Yu Lu Liang Liu Mine The memory cloud Ramcloud uses log segments to store the data, so when a large number of small files are stored in the Ramcloud cluster, each small file exclusively takes over the entire segment, resulting in more fragment fragments, This results in low memory efficiency and a large amount of memory space wasted. To solve this problem, a ramcloud small file storage optimization strategy based on file classification is proposed. This strategy first divides the small file into the structure related document according to the document correlation characteristic, logos ...
