Java not updating cam newton dating sierra
I don't see any reason why you can't have 4 different temp tables I would first start doing it without threads - it is additional complication - look at your times real life situations, if this is some application which you need to run once to update or you'll be using it all the time see how it goes first in termas of time especially if it ios mostly one time opperation- if you need it then think about threads @for_yan and @CEHJ: Thanks for the reply.This would be a one time operation or load that i would be performing once in a few months.With database in such situation you are much more flexible than with files. Could i create say 4 different temp tables which would contain all the records to be updated.Could i use threads on these temp tables so that the records could get updated simultaneously and could complete fast.What I thought was that I'll create 4 temp tables and distribute the total load in these 4 tables and simultaneously kick off 4 threads which would run simultaneously and load the data.
Here are interesting links, explanation @for_yan and @gudii9: Basically why i wanted this to happen was that i had another question asked in the link: Previous Question I was thinking i would extract the initiallly available data into a text or a csv file and update the file after the entire data for every record is available. I was thinking as suggested by you to extact the data in a text or a csv file and update the record or a line when the complete data is present. If this is Oracle - it is designed for big tables and 5 million rows is not that dramatic.
I was thinking to do this on the database side but was apprehensive as i have more than 5 million records to work with. That's tiny for a Map, which is the new record for update Sorry, I did not get you. When it comes to updating rows, as you saw, database is definitely much better place to deal with You can do it just row by row raeding rthe rows - calculation the remaning rcolumns and filling them in Actually database and JDBC talke care of the memory issues for you, so it is not that bad as you may think.
I need to decide as if i take either to do it on the database side or to do it externally via files, later i would not be able to turn back. You can devise some way to select and update grouped in certain chunks.
During the automatic update from JRE 7 to JRE 8, if a user only has one version of Java 7 the auto-update process will replace that JRE 7 with the latest version of JRE 8 leaving only JRE 8 in the system.
OS X users can only have one JRE available through web browsers so OS X users will only have JRE 8 available through the web browser after the upgrade On Windows, the auto-update process updates only the latest JRE on your system.
