c# - NetworkStream ReadAsync cancellation -

this question has answer here: networkstream.readasync cancellation token never cancels 4 answers i trying add "timeout" readasync method networkstream . i want cancel readasync after specific time. for example: ctstimeout.cancelafter(10); int bytesread = await nsstream.readasync(newarr, 0, newarr.length, ctstimeout.token); but method still waiting response server. is possible cancel method in reading state? networkstream (or stream inheritance) doesn't support cancellation. readasync method accepts cancellation token, sure; allows know if cancellation requested before read completed. readasync wraps beginread , endread --which offer no way cancel read operation. to cancel read need dispose or close networkstream object.

design patterns - How many rows to insert per notification in a notification system? -

following on this question looking @ building similar notification system , have question (which has obvious answer think i'd prefer have other opinions): if particular post generated million likes, , adds comment post, need notify million people liked post comment added. way achieve write million rows notificationread table has notificationid , 'send' them various users? i can't visualise other approach let me keep track of read notifications , potentially inserting million rows per post per notification sounds daunting , expensive. is there other way it? using sql server 2014 , application server coldfusion 2016 first off, if need push notifications, there's no escaping fact need somehow notify each of million users. don't need store notifications on server. one make reasonable assumptions: most activity occur on recent posts (say, posts less week old) most users not respond notification immediately with this, can skip storing no

Java stream file to socket as fast as possible -

i have file of bytes mybytes.dat , , i'm writing tcp server/client, server sends contents of mybytes.dat client on socket. if mybytes.dat read memory, application can send data @ 160mb/s on local network stack. however, i'm trying stream datafiles > 1gb, , shouldn't read memory. this related solution sending file in chunks seems appropriate; however, more efficient read large chunks of file memory (ie. maybe 1mb @ time in buffer) , write these smaller chunks (32kb) socket? if reasonable, how can 1 use bufferedfilereader read large chunks, , write smaller chunks outputstream? started, let me declare @ least variables: bufferedinputstream blobreader = new bufferedinputstream(newinputstream("mybytes.dat"), 1024*1024); outputstream socketwriter = socket.getoutputstream(); what correct way connect blobreader socketwriter, such maintain enough bytes in memory ensure application not limited disk reads? or offbase line of reasoning?
