Optimize Big Data Table query and data table Optimization 1: Index, the first thing we think of first is creating an index. Creating an index can multiply the query efficiency and save time. However, if the data volume is too large, simply creating an index will not help. We know that if we count the query in a large a

The DB2 big data table data deletion method is slow and unacceptable when the table data volume is deleted from table_name in millions. In addition, delete is more unacceptable when deleting multiple tables. Find the method and find it very fast. The procedure is as follows: www.2cto.com (1). Create a new file named [e

Python reads Big Data txt and Python reads data txt If you call the read () method directly for large file objects, unpredictable memory usage may occur. A good way is to use a fixed-length buffer to constantly read the file content. That is, through yield. When I read two multi-G txt files using Python, I simply used the readlines method, and the result collapse
