to this definition table.2. Use the Columnstore index to include each column of the table. If you do not, querying columns that are not in the Columnstore index will not benefit from the efficiency of the Columnstore index.3. Structured queries, avoid associating two or more large tables, and increase efficiency by associating multiple small definition tables with a large actual expense table.when to use Columnstore indexes is not recommended 1. Avoid direct string filtering on columns that sto

called SubSpace Tracking Algorithm (SP). It has a proven refactoring performance similar to the LP algorithm, and the computational complexity is very low. This algorithm can be used without noise and noise. In the case of no noise, if the matrix Phi satisfies the RIP condition with certain parameters, the SP algorithm can reconstruct the original signal accurately. When the measurement is not accurate, or the signal is not strictly sparse, the reconstructed distortion has an upper bound, which
