file once, and algorithm 1 io times more, so the algorithm 2 than algorithm 1 in engineering has better operability. Step two: Find Top 10 (Find out the 10 most frequent occurrences)algorithm One: ordinary sort (we only use to find Top10, so all sorts have redundancy)I think for the sorting algorithm, we are not unfamiliar, here is not to repeat, we should pay attention to the sorting algorithm time complexity is NLGN, in this topic, 3 million recor

Save Word% 5000 to 5000 small files The average file is about 200K Continue to split over 1M files until less than 200K Use map to count how often each word appears On 5000 words using heap sort or merge sort distributed top N problem The vast number of data distributed in 100 computers, the first ten.

Its value must be a negative integer. If you add a value that exceeds the limit, only the last added element will be included. Must be used with "$each".Db.foo.update ({"_id": "1

fact that the actual number of rows is much larger than the estimated number of rows, we can try using a hash join,forcescan.2. Increase the Where condition so that the number of rows returned has a higher selectivity.3. Do not use TOP1, and use the number above the top 10 to make the estimated number of rows larger, compared to 5 of the query we changed from TOP1 to TOP10, then the execution plan becomes 6.Figure 6.

, compared to 5 of the query we changed from TOP1 to TOP10, then the execution plan becomes 6. Figure 6. Implementation plan for TOP 10 This is due to the fact that LOOP join can return a limited number of rows more quickly when the number of rows is low, which is equivalent to a fast n hint to the table, but when the number of rows increases, the optimizer prefers to use merge or hash to complete the operation, with better performance in extreme ca

memory footprint is the size of the gold, so that mono has no need to lock up a lot of memory, is a very wasteful thing. therefore, in the UWA Assessment report, we have counted the accumulated function heap memory allocations in the testing process for the research and development team, so that we can quickly view the underlying code implementation by looking at the function of the heap memory allocation TOP10, and locate whether there is any code t

Linux Files are sorted by column to get top-related awk target: Data in Hive, sorted by the total traffic size of users in each category. now we need to retrieve the top10. Hive of each category and use order by categoryId and traffic desc to sort the data, but we cannot obtain top for each categoryId. because limit affects the entire final result, it cannot be used. finally, we decided to export the text and use awk to get the

the above scenario, we can usually have the following centralized workaround: 1. Using hints, since we know this is due to the fact that the actual number of rows is much larger than the estimated number of rows, we can try using a hash join,forcescan. 2. Increase the Where condition so that the number of rows returned has a higher selectivity. 3. Do not use TOP1, and use the number above the top 10 to make the estimated number of rows larger, compared to 5 of the query we changed from TOP1 to
