Hi
Actually we run on amazon EC2 large instance = 7.5 GB memory and we don't
use ESB only local disk as /mnt
here is my code o insert the data :
public void insertChannelShow(String showId, String channelId, String
airDate, String duration, String title, String parentShowId, String genre,
String price, String subtitle) throws Exception {
Calendar calendar = Calendar.getInstance();
dateFormat.setCalendar(calendar);
Date air = dateFormat.parse(airDate);
calendar.setTime(air);
String key = String.valueOf(calendar.getTimeInMillis()) + ":" +
showId + ":" + channelId;
long timestamp = System.currentTimeMillis();
cassandraClient.insert("Keyspace1",
key,
new ColumnPath("channelShow", null,
("duration").getBytes("UTF-8")),
duration.getBytes("UTF-8"),
timestamp,
ConsistencyLevel.ONE);
cassandraClient.insert("Keyspace1",
key,
new ColumnPath("channelShow", null,
("title").getBytes("UTF-8")),
title.getBytes("UTF-8"),
timestamp,
ConsistencyLevel.ONE);
cassandraClient.insert("Keyspace1",
key,
new ColumnPath("channelShow", null,
("parentShowId").getBytes("UTF-8")),
parentShowId.getBytes("UTF-8"),
timestamp,
ConsistencyLevel.ONE);
cassandraClient.insert("Keyspace1",
key,
new ColumnPath("channelShow", null,
("genre").getBytes("UTF-8")),
genre.getBytes("UTF-8"),
timestamp,
ConsistencyLevel.ONE);
cassandraClient.insert("Keyspace1",
key,
new ColumnPath("channelShow", null,
("price").getBytes("UTF-8")),
price.getBytes("UTF-8"),
timestamp,
ConsistencyLevel.ONE);
cassandraClient.insert("Keyspace1",
key,
new ColumnPath("channelShow", null,
("subtitle").getBytes("UTF-8")),
subtitle.getBytes("UTF-8"),
timestamp,
ConsistencyLevel.ONE);
}
of course I've initialized my connection like this :
tr = new TSocket(server, 9160);
TProtocol proto = new TBinaryProtocol(tr);
cassandraClient = new Client(proto);
tr.open();
I've actually 2 machine on amazon EC2. 1 large from here I run the insert
data process and cassandra. The second machine just run cassandra but it's
on small instance just 2GB memory.
Thanks
