copy

I want to load a massive amount of data into PostgreSQL. Do you know any other "tricks" apart from the ones mentioned in the PostgreSQL's documentation? What have I done up to now? 1) set the following parameters in postgresql.conf (for 64 GB of RAM): shared_buffers = 26GB work_mem=40GB maintenance_work_mem = 10GB # min 1MB default: 16 MB effective_cache_size = 48GB max_wal_senders = 0 # max number of walsender processes wal_level = minimal # minimal, archive, or hot_standby synchronous_commit = off # apply when your system only load data (if there are other updates from clients it can result

What is the best way to move/copy file while maintaining all its attributes (Date created, Date, etc)? Thank you If you are using Java 7, use java.nio.file.Files.copy(Path source, Path target, CopyOption... options) Use the COPY_ATTRIBUTES option to maintain the last modified time: COPY_ATTRIBUTES Attempts to copy the file attributes associated with this file to the target file. The exact file attributes that are copied is platform and file system dependent and therefore unspecified. Minimally, the last-modified-time is copied to the target file if supported by both the source and target file

Is there a way to hook into the Windows File Copy API from C#? I'm aware this would require unmanaged code, but a code sample or starter would be helpful. I've already seen the C++ code, but it's all greek. UPDATE: I apologize, I should have been more clear about my intentions. I wish to actually change the copy feature of Windows to be more rigid (e.g. allow queing, scheduling, handle restarts, pauses, etc.). When I said hook, I meant API hook so that when someone starts a copy I get the sources and destinations and can handle it to my heart's desire. I'm old school and used to hook the Mac

Good afternoon, I am new to Canvas in HTML 5 and in using it with Javascript. But I can see how powerful this really is and I needed help. I have done a search and could not find a clear answer to this. Perhaps someone here can help. I have created a context on the Canvas with a background image in place. Now, I want crop or copy a part of that image which is contained in Polygon Data and place it else where on the screen. I know how to create the background image. I know how to create a polygon over that image and I know how to copy image data to another part of the screen. So how would I

I am looking for a solutions for my MySQL data copying related problem. I have a table TAB1 in a database DB1 that contains some data. Now I want some of these data rows to be migrated to another table TAB2 to some another database DB2. What would be an ideal way to write such a SQL script for MySQL server. I cannot write java/php program etc because I don't have access to the code base. Any example links will be helpful. I know this can be done in Oracle via DBLink but how to do it in MySQL. Thanks insert into db2.table2 (field1,field2,..,fieldN) select field1,field2,..,fieldN from db1.table1

Because this seems like what I have to do to get this effect: $arr = ['a'=>'first', 'b'=>'second', ...]; $iter = new ArrayIterator( $arr ); // Do a bunch of iterations... $iter->next(); // ... $new_iter = new ArrayIterator( $arr ); while( $new_iter->key() != $iter->key() ) { $new_iter->next(); } Edit: Also, just to be clear, should I NOT be modifying the base array with unset() ? I figure the array iterator stores its own copy of the base array, so using offsetUnset() doesn't seem right. ArrayIterator does not implement a tell() function, but you can emulate this, and then use seek() to go to
