chunks

问题 Context We have a batch job that replicates localized country names (i.e. translations of country names to different languages) to our DB from the external one. The idea was to process all localized country names for a single country in 1 chunk (i.e. first chunk - all translations for Andorra, next chunk - all translations for U.A.E., etc.). We use JdbcCursorItemReader for reading external data + some oracle analytic functions to provide total number of translations available for the country:

问题 I have a window service and i want it to be able to upload/download large (around 4MB) files (Img, music etc.) in chunks. I tried to do that by changing the 'maxBufferSize' 'maxRecivedMessageSize' etc. in both the service and client app.config files, but unfortunately it didn't work. My question is how I can upload/download files in chunks. and if I can do that just with the App.config file? Thank! 回答1: WCF doesn't have direct support for chunking (it always sends whole data as single chunk)

问题 I want to transform an array: ["a", "b", "b", "a", "b", "a", "b"] to ["a", "a", "b", "b", "a", "b", "b"] or ["b", "b", "a", "a", "b", "b", "a"] I want to group the array in a way where a special condition matches. In my case when item == 'a' or item == 'b' . And these groups I want to chunck into groups of 2. I'm currently a bit confused how to do it the elegant way. Can anyone help? Maybe the following makes it more clear: I like to group the array into 'a' and 'b'-items first like so: a

问题 I've written a relatively simple Spark job in Scala which reads some data from S3, performs some transformations and aggregations and finally stores the results into a repository. At the final stage, I have an RDD of my domain model and I would like to group them into chunks of elements so that I can do some mass insertions in my repository. I used the RDDFunctions.sliding method to achieve that and it's working almost fine. Here is a simplified version of my code: val processedElements: RDD

问题 Lets assume I have a CMTimeRange constructed from start time zero, and duration of 40 seconds. I want to split this CMTimeRange into multiple chunks by a X seconds divider. So the total duration of the chunks will be the same duration as the original duration, and each startTime will reflect the endTime of of the previous chunk. The last chunk will be the modulus of the left over seconds. For example, for video of 40 seconds, and divider of 15 seconds per chunk: First CMTimeRange - start time

问题 I am making an app which needs to stream audio to a server. What I want to do is to divide the recorded audio into chunks and upload them while recording. I used two recorders to do that, but it didn't work well; I can hear the difference between the chunks (stops for couple of milliseconds). How can I do this? 回答1: Your problem can be broken into two pieces: recording and chunking (and uploading, but who cares). For recording from the microphone and writing to the file, you can get started

问题 I want to split a list into chunks using values of of another list as the range to split. indices = [3, 5, 9, 13, 18] my_list = ['a', 'b', 'c', ..., 'x', 'y', 'z'] So basically, split my_list from range: my_list[:3], mylist[3:5], my_list[5:9], my_list[9:13], my_list[13:18], my_list[18:] I have tried to indices into chunks of 2 but the result is not what i need. [indices[i:i + 2] for i in range(0, len(indices), 2)] My actual list length is 1000. 回答1: You could also do it using simple python.

问题 I have binary basically, say it's 300 in length. How would I split (much like using explode) it into 8 bit chunks? I look at chunk_split() but it only seems to have an 'end' parameter, not an option to put it into an array.. Or can it be socketed into an array? The end 8 digits can be below 8 (in case a miscopy from someone, and it's 4) so no validation is needed, just consistantly in 8 number chunks from the start to end. 回答1: str_split: $chunks = str_split($data, 8); 来源： https:/

问题 I am processing a csv -file which is 2.5 GB big. The 2.5 GB table looks like this: columns=[ka,kb_1,kb_2,timeofEvent,timeInterval] 0:'3M' '2345' '2345' '2014-10-5',3000 1:'3M' '2958' '2152' '2015-3-22',5000 2:'GE' '2183' '2183' '2012-12-31',515 3:'3M' '2958' '2958' '2015-3-10',395 4:'GE' '2183' '2285' '2015-4-19',1925 5:'GE' '2598' '2598' '2015-3-17',1915 And I want to groupby ka and kb_1 to get the result like this: columns=[ka,kb,errorNum,errorRate,totalNum of records] '3M','2345',0,0%,1
