batch-processing

I found existing questions similar to this one that did not actually have a clear answer to the question. A normal batch preparedstatement with one sql query would look something like this: private static void batchInsertRecordsIntoTable() throws SQLException { Connection dbConnection = null; PreparedStatement preparedStatement = null; String insertTableSQL = "INSERT INTO DBUSER" + "(USER_ID, USERNAME, CREATED_BY, CREATED_DATE) VALUES" + "(?,?,?,?)"; try { dbConnection = getDBConnection(); preparedStatement = dbConnection.prepareStatement(insertTableSQL); dbConnection.setAutoCommit(false);

This is a bit of a question with some level of detail to it, so let me first explain the situation, then my implementation and last the question so you understand best. As of April 4 an update is added and the issues are narrowed down to one pending issue, see the bottom of this question for the up to date info. TLDR; I have a long route returned from Google Maps Directions API and want an Elevation chart for that route. Too bad it doesn't work because it's requested via GET and the URL maximum length is 2.048 chars which get exceeded. I splitted the requests; guaranteed the correct processing

I am new to hibernate i have doubt in hibernate batch processing, i read some tutorial for hibernate batch processing they said Session session = SessionFactory.openSession(); Transaction tx = session.beginTransaction(); for ( int i=0; i<100000; i++ ) { Employee employee = new Employee(.....); session.save(employee); } tx.commit(); session.close(); Hibernate will cache all the persisted objects in the session-level cache and ultimately your application would fall over with an OutOfMemoryException somewhere around the 50,000th row. You can resolve this problem if you are using batch processing

I have to do batch processing to automate business process. I have to poll directory at regular interval to detect new files and do processing. While old files is being processed, new files can come in. For now, I use quartz scheduler and thread synchronization to ensure that only one thread can process files. Part of the code are: application-context.xml <bean id="methodInvokingJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"><br/> <property name="targetObject" ref="documentProcessor" /><br/> <property name="targetMethod" value="processDocuments" /><br/> <

I want to check if a process is running or not ? if the process is not running, then i execute it (in this example I took the calculator with process name = calc.exe) I started the batch script, but I have a syntax problem I believe ! @echo off Set MyProcess=calc.exe echo %MyProcess% pause for /f "tokens=1" %%i In ('tasklist /NH /FI "imagename eq %MyProcess%"') do set ff=%%i echo %ff% If /i %ff%==%MyProcess% (Echo %ff% est en cours d^'execution) Else (Start %MyProcess%) pause Here's another way to do it using your code as a base: @echo off Set "MyProcess=calc.exe" echo "%MyProcess%" tasklist

I'm trying to create a WriteBatch to keep control of one of my dynamic references in my database. My app have a simple User-Follow-Post-Feed model where I want my user to see in his feed the posts of all the users he is following. What I'm doing after research on Firebase examples (as Firefeed ) and a lot of posts on Stack Overflow. The optimal idea is keep a path ( collection in this case) where I store the Ids of the posts that my user should see in his feed, which means keep control of copy and delete every post of all the users that he follow/unfollow. I made my Cloud functions for keep
