Alexander Belyak updated IGNITE-19247:
--------------------------------------
Description:
Simple example:
{code:java}
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.Statement;
public class TimeoutExceptionReproducer {
private static final String DB_URL = "jdbc:ignite:thin://172.24.1.2:10800";
private static final int COLUMNS = 100;
private static final String TABLE_NAME = "t1";
private static final int ROWS = 1000;
private static final int TABLES = 1000;
private static final int BATCH_SIZE = 100;
private static String getCreateSql(String tableName) {
StringBuilder sql = new StringBuilder("create table
").append(tableName).append(" (id int primary key");
for (int i = 0; i < COLUMNS; i++) {
sql.append(", col").append(i).append(" varchar NOT NULL");
}
sql.append(")");
return sql.toString();
}
private static void createTables(Connection connection, String tableName)
throws SQLException {
try (Statement stmt = connection.createStatement()) {
System.out.println("Creating " + tableName);
stmt.executeUpdate("drop table if exists " + tableName );
stmt.executeUpdate(getCreateSql(tableName));
}
}
private static String getInsertSql(String tableName) {
StringBuilder sql = new StringBuilder("insert into
").append(tableName).append(" values(?");
for (int i = 0; i < COLUMNS; i++) {
sql.append(", ?");
}
sql.append(")");
return sql.toString();
}
private static void insertData(Connection connection, String tableName)
throws SQLException {
long ts = System.currentTimeMillis();
try (PreparedStatement ps =
connection.prepareStatement(getInsertSql(tableName))) {
int batch = 0;
for (int i = 0; i < ROWS; i++) {
ps.setInt(1, i);
for (int j = 2; j < COLUMNS + 2; j++) {
ps.setString(j, "value" + i + "_" + j);
}
ps.addBatch();
batch++;
if (batch == BATCH_SIZE) {
batch = 0;
ps.executeBatch();
ps.clearBatch();
long nextTs = System.currentTimeMillis();
System.out.println("Batch " + BATCH_SIZE + " took " +
(nextTs - ts) + " to get " + i + " rows");
ts = nextTs;
}
}
if (batch > 0) {
batch = 0;
ps.executeBatch();
ps.clearBatch();
}
}
}
public static void main(String[] args) throws SQLException {
try (Connection connection = DriverManager.getConnection(DB_URL)) {
for (int i = 0; i < TABLES; i++) {
String tableName = TABLE_NAME + i;
createTables(connection, tableName);
insertData(connection, tableName);
}
}
}
}
{code}
lead to timeout exception:
