问题
I am trying to connect Gemfire 8.2 using apache calcite geode adopter. As per following logs its connectied properly but while try to execute query getting exception .
Note : http://calcite.apache.org/news/2018/03/19/release-1.16.0/
Moreover, a new adapter to read data from Apache Geode was added in this release. In addition, more progress has been made for the existing adapters
1) Connection class
package com.khan.vaquar;

public class GemfireJDBCTest1 {
public static void main(String[] args) {
//
new GemfireJDBCTest1().connection1();
//
//new GemfireJDBCTest1().connection2();
}
/***

*/
public void connection1() {
try {
Class.forName(org.apache.calcite.jdbc.Driver.class.getName());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Properties info = new Properties();
info.setProperty("lex", "JAVA"); // Enables case sensitivity
info.setProperty("model",
"C://Users//vkhan//Documents//scala-workspace//CalciteGemfire//src//com//khan//vaquar//myModel.json "); // See
// section
// below
try {
Connection connection = DriverManager.getConnection("jdbc:calcite:", info);
Statement statement = connection.createStatement();
ResultSet resultset = statement.executeQuery("select * from account"); //("select * from \"account\"");
final StringBuilder buf = new StringBuilder();
while (resultset.next()) {
ResultSetMetaData metaData = resultset.getMetaData();
/*
for (int i = 1; i <= metaData.getColumnCount(); i++) {
}
*/
}
System.out.println("Conected---------------------------");
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
2) JSON "myModel.json"

回答1:
The Geode Adapter is compiled with Geode version: 1.3 (https://github.com/apache/calcite/blob/master/pom.xml#L79) that corresponds to Gemfire 9.x.
Because the Gemfire 8.x is code incompatible with Gemfire 9.x. you would not be able to use the Geode Adapter on the Gemfire 8.x or older. Furthermore the OQL in Gemfire 8.x doesn't support GROUP BY construct either.
回答2:
I have made following changes into my code to connect Gemfire 9.6 using apache calcite.
1) Geode or Gemfire has no concepts of schema however in apache calcite we have to define it,example
final String geodeModelJson =
"inline:"
+ "{\n"
+ " version: '1.0',\n"
+ " schemas: [\n"
+ " {\n"
+ " type: 'custom',\n"
+ " name: 'TEST',\n"
+ " factory: 'org.apache.calcite.adapter.geode.rel.GeodeSchemaFactory',\n"
+ " operand: {\n"
+ " locatorHost: 'localhost', \n"
+ " locatorPort: '10334', \n"
+ " regions: 'test1', \n"
+ " pdxSerializablePackagePath: 'org.apache.calcite.adapter.geode.domain.*' \n"
+ " }\n"
+ " }\n"
+ " ]\n"
+ "}";
Here you can see schema name =TEST , this is mandatory to connect gemfire else will get error no object found.
Then you have to use in sql
ResultSet resultSet = statement.executeQuery("select * from \"TEST\".\"test1\"");
2) You need to define your region name in "" else it will convert to uppercase and gemfire region name is case sensetive so account ,ACCOUNT,Account are three diffrent region in gemfire
\"TEST\".\"test1\"
Here you find full Java code :
