batch-insert

I need to insert a huge amount of nodes with relationships between them into Neo4j via REST API's Batch endpoint, approx 5k records/s (still increasing). This will be continuous insertion 24x7. Each record may require creating one node only, but other may require two nodes and one relationship being created. Can I improve the performance of the inserts by changing my procedure or modifying the settings of Neo4j? My progress so far: 1. I have been testing with Neo4j for a while, but I could not get the performance I needed Test server box: 24 cores + 32GB RAM Neo4j 2.0.0-M06 installed as a

I am fresh to Codeigniter. I have a form which looks something like this. <tr> <td><input type="text" name="Name[0]" value=""></td> <td><input type="text" name="Address[0]" value=""><br></td> <td><input type="text" name="Age[0]" value=""></td> <td><input type="text" name="Email[0]" value=""></td> </tr> <tr> <td><input type="text" name="Name[1]" value=""></td> <td><input type="text" name="Address[1]" value=""><br></td> <td><input type="text" name="Age[1]" value=""></td> <td><input type="text" name="Email[1]" value=""></td> </tr> There may be from 0 to n rows, usually 5 to 10 rows. How do I

I am inserting many records using JDBC batch inserts. Is there any way to get the generated key for each record? Can I use ps.getGeneratedKeys() with batch inserts? I am using oracle.jdbc.OracleDriver final String insert = "Insert into Student(RollNumber, Name, Age) values(StudentSEQ.nextval, ? , ?)"; final int BATCH_SIZE = 998; int count = 0; Connection con = null; PreparedStatement ps = null; try { con = getConnection(); ps = con.prepareStatement(insert); for (Student s : students) { ps.setString(1, s.getName()); ps.setInt(2, s.getAge()); ps.addBatch(); count++; if (count % BATCH_SIZE == 0)

I have some monthly weather data that I want to insert into an Oracle database table but I want to insert the corresponding records in a batch in order to be more efficient. Can anyone advise as to how I'd go about doing this in Python? For example let's say my table has four fields: a station ID, a date, and two value fields. The records are uniquely identified by the station ID and date fields (composite key). The values I'll have to insert for each station will be kept in a list with X number of full years worth of data, so for example if there are two years of values then the value lists

Does JPA/EJB3 framework provide standard way to do batch insert operation...? We use hibernate for persistence framework, So I can fall back to Hibernate Session and use combination session.save()/session.flush() achieve batch insert. But would like to know if EJB3 have a support for this... Neither JPA nor Hibernate do provide particular support for batch inserts and the idiom for batch inserts with JPA would be the same as with Hibernate: EntityManager em = ...; EntityTransaction tx = em.getTransaction(); tx.begin(); for ( int i=0; i<100000; i++ ) { Customer customer = new Customer(.....);
