chunks

问题 I was wondering how I could determine in my ItemWriter , whether Spring Batch was currently in chunk-processing-mode or in the fallback single-item-processing-mode. In the first place I didn't find the information how this fallback mechanism is implemented anyway. Even if I haven't found the solution to my actual problem yet, I'd like to share my knowledge about the fallback mechanism with you. Feel free to add answers with additional information if I missed anything ;-) 回答1: The

问题 What is the best way to divide a list into roughly equal parts? For example, if the list has 7 elements and is split it into 2 parts, we want to get 3 elements in one part, and the other should have 4 elements. I'm looking for something like even_split(L, n) that breaks L into n parts. def chunks(L, n): """ Yield successive n-sized chunks from L. """ for i in xrange(0, len(L), n): yield L[i:i+n] The code above gives chunks of 3, rather than 3 chunks. I could simply transpose (iterate over

问题 I am new to netty and I am attempting to transfer a chunkedfile from a server to a client. Sending the chunks work just fine. The problem is on how to handle the received chunks and write them to a file. Both methods that I tried give me a direct buffer error. Any help would be greatly appreciated. Thanks! @Override protected void decode(ChannelHandlerContext ctx, ByteBuf in, List<Object> out) throws Exception { System.out.println(in.toString()); //METHOD 1: write to file FileOutputStream fos

问题 The following code splits a stream of objects into chunks of 1000, processes them on materialisation and returns the total number of objects at the end. In all cases the number returned is correct unless the stream size happens to be 1. In the case the stream size is 1, the number returned is 0. Any help would be greatly appreciated. I have also had to hack the return call in the case there are no records in the stream to be 0. I'd like to fix this too. AtomicInteger recordCounter = new

问题 I am trying to understand how Webpack 4 code splitting works under the hood. Is there a hidden code which makes a http request for next chunk? Follow up question: If I split code between login.js(login page) and app.js(actual app), is it possible to intercept the call from login.js for next chunk and based on successful authentication or not, serve app.js if successful or serve error.js on failed authentication? 回答1: Webpack v4 has latest upgrades. Previously if we do code splitting, You can

问题 I have an XML with a text node, and I need to split this string into multiple chunks using XSLT 2.0. For example: <tag> <text>This is a long string 1This is a long string 2This is a long string 3This is a long string 4</text> </tag> The output should be: <tag> <text>This is a long string 1</text> <text>This is a long string 2</text> <text>This is a long string 3</text> <text>This is a long string 4</text> </tag> Note that I deliberately set the chunk size to the length of each statement so

问题 I'm running an analysis in an R Notebook and I would like all plots created in R chunks to be saved as individual PDF files in addition to appearing in the .nb.html notebook output. The problem The problem I'm having is that, when the notebook is run, it does not save plots to the dir specified in the chunk option fig.path = "figures/" either when specified in the individual chunk header: #```{r fig.path = "figures/"} plot(x, y) #``` or when specified with the global chunk options: #```{r

问题 I need to get a list of chunks after sharding inside my Java code. My code is simple and looks like this: Mongo m = new Mongo( "localhost" , 27017 ); DB db = m.getDB( "admin" ); Object cr = db.eval("db.printShardingStatus()", 1); A call of eval() returns an error: Exception in thread "main" com.mongodb.CommandResult$CommandFailure: command failed [$eval]: { "serverUsed" : "localhost/127.0.0.1:27017" , "errno" : -3.0 , "errmsg" : "invoke failed: JS Error: ReferenceError: printShardingStatus is

问题 What is the right (GIO/Glib/GTK/Gnome) way to process GInputStream in non-blocking manner and chunk-by-chunk? I have an application which is downloading (through libsoup) and processing a data stream in chunks and doing other actions in parallel. I am calling g_input_stream_read_async on GInputStream (received from soup_session_send_finish and giving it a reasonable size of chunk to read (in my case 2048 bytes). After I receive a g_input_stream_read_async callback, I want to continue reading
