Alexander Belyak updated IGNITE-19247:
--------------------------------------
Description:
Code below just create TABLES tables with COLUMNS+1 columns and insert ROWS
rows into each table (with SLEEP ms interval between operations).
Simple example:
{code:java}

").append(tableName).append(" (id int primary key");
for (int i = 0; i < COLUMNS; i++) {

}

s();
}
}
private static String getInsertSql(String tableName) {

").append(tableName).append(" values(?");
for (int i = 0; i < COLUMNS; i++) {

}

}
ps.addBatch();
batch++;
if (batch == BATCH_SIZE) {
batch = 0;
ps.executeBatch();
ps.clearBatch();

}
}
}
private static int testData(Connection connection, String tableName) throws
SQLException {
try (Statement stmt = connection.createStatement();

tableName);) {
rs.next();
int count = rs.getInt(1);
int result = ROWS - count;
if (result == 0) {
System.out.println("Found " + count + " rows in " + tableName);
} else {
System.err.println("Found " + count + " rows in " + tableName +
" instead of " + ROWS);
}
return result;
}
}
public static void main(String[] args) throws SQLException {
int lostRows = 0;
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);
lostRows += testData(connection, tableName);
}
}
System.exit(lostRows);
}
}

lead to timeout exception:
