Implementing some MySQL wire protocol so that Manticore Search could support JPA and MyBatis framework #1618

guofengzh · 2023-11-23T07:20:19Z

Is your feature request related to a problem? Please describe.
Manticore failed to work with HikariCP so that it is not easier to use it on Spring boot platform with MySQL connectors. HikariCP is a popular and default data source used on Spring boot platform.

Describe the solution you'd like
It is acceptable that Manticore does not support full MySQL wire protocol, but it might be good to implement some features, like version and isolation level requests so that we can use JPA or Mybatis to access Manticore easier.

Describe alternatives you've considered
N/A

Additional context
Here is a project to demostrate the use of JPA and MyBatis with Manticore, but it uses a simple data source other than HikariCP. It also demostrates what error throws when using HikariCP.

It seems that the version of your JDK is less than 17.

This is a Spring boot 3 project that requires at least Java 17.

Please also verify, according to the doc, that mysql_version_string is set to 5.0.37.

I just verify again that the project runs well on Java 17 and 21, on WIndows 10 here.

What is wrong here? Looks good to me at first glance.

guofengzh · 2023-11-24T01:02:37Z

Sorry I didn't make it clear.

The current code does not use HikariCP, so it works fine.

The improvement I hope for is that Manticore can support datasources like HikariCP so that Manticore can be easily used in Spring boot applications.

In DataSourceConfig.java, the following code:

     @Bean
     public DataSource dataSource(){
         return createMyBatisPooledDataSource();
         // Uncommenting the following statement will throw "java.sql.SQLException: Could not map transaction isolation '<empty>' to a valid JDBC level."
         // return createHikariDataSource();
     }

Modify it to:

     @Bean
     public DataSource dataSource(){
         // return createMyBatisPooledDataSource();
         // Uncommenting the following statement will throw "java.sql.SQLException: Could not map transaction isolation '<empty>' to a valid JDBC level."
         return createHikariDataSource();
     }

The problem I reported will occur:

java.sql.SQLException: Could not map transaction isolation '<empty>' to a valid JDBC level.
...

sanikolaev · 2023-11-24T17:09:27Z

@guofengzh do you know what exactly it expects from mysql?

E.g. Manticore works like this:

root@4362a20a1625:/manticore-demo# mysql -P9306 -h0 -e "SELECT @@session.tx_isolation"
+------------------------+
| @@session.tx_isolation |
+------------------------+
|                      0 |
+------------------------+

Is this what breaks it? What's expected instead? Can you please provide a full dialog between it and mysql/mariadb, so we can see what queries need to be handled differently for that to work?

guofengzh · 2023-11-26T04:11:19Z

From what you did, I see the result of my Manticore:

mysql> SELECT @@session.tx_isolation;
+------------------------+
| @@session.tx_isolation |
+------------------------+
| <empty>                |
+------------------------+

This is the source code of com.mysql.cj.jdbc.ConnectionImpl.getTransactionIsolation(), which failed to work with HikariCP:

    @Override
    public int getTransactionIsolation() throws SQLException {

        synchronized (getConnectionMutex()) {
            if (!this.useLocalSessionState.getValue()) {
                String s = this.session.queryServerVariable(
                        versionMeetsMinimum(8, 0, 3) || (versionMeetsMinimum(5, 7, 20) && !versionMeetsMinimum(8, 0, 0)) ? "@@session.transaction_isolation"
                                : "@@session.tx_isolation");

                if (s != null) {
                    Integer intTI = mapTransIsolationNameToValue.get(s);
                    if (intTI != null) {
                        this.isolationLevel = intTI.intValue();
                        return this.isolationLevel;
                    }
                    throw SQLError.createSQLException(Messages.getString("Connection.12", new Object[] { s }), MysqlErrorNumbers.SQL_STATE_GENERAL_ERROR,
                            getExceptionInterceptor());
                }
                throw SQLError.createSQLException(Messages.getString("Connection.13"), MysqlErrorNumbers.SQL_STATE_GENERAL_ERROR, getExceptionInterceptor());
            }

            return this.isolationLevel;
        }
    }

By debugging, for my case, s is "<empty>", The following statement failed to translate the value of s to the expected value:

Integer intTI = mapTransIsolationNameToValue.get(s);

mapTransIsolationNameToValue is of HashMap type, and defined statically in this class:

    private static Map<String, Integer> mapTransIsolationNameToValue = null;
    static {
        mapTransIsolationNameToValue = new HashMap<>(8);
        mapTransIsolationNameToValue.put("READ-UNCOMMITED", TRANSACTION_READ_UNCOMMITTED);
        mapTransIsolationNameToValue.put("READ-UNCOMMITTED", TRANSACTION_READ_UNCOMMITTED);
        mapTransIsolationNameToValue.put("READ-COMMITTED", TRANSACTION_READ_COMMITTED);
        mapTransIsolationNameToValue.put("REPEATABLE-READ", TRANSACTION_REPEATABLE_READ);
        mapTransIsolationNameToValue.put("SERIALIZABLE", TRANSACTION_SERIALIZABLE);
    }

I set s to "READ-UNCOMMITTED" by the dubug tool, All the tests passed.

However, I don't know why on the MySQL terminal I can't set up the isolation level.

If the MySQL terminal is connected to MySQL server, I can use the following statement to set it:

SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED;

Exit the terminal and reconnect to MySQL, I can see the isolation level is changed. But the above statement does not works with Manticore.

guofengzh · 2023-11-28T05:34:07Z

@sanikolaev, how can I set the Manticore transaction isolation level by the command line, or how can I change the value of @@session.tx_isolatio, so I can move on.

As documented, Manticore do not aim to provide isolation (it is overly isolated). so there will be no problem setting one of that values, like "READ-COMMITTED", although it is semantically incorrect, but very close.

My test codes in my project use different transaction to operate Manticore. If I place these operations in the same transaction, for example:

    @Test
    @Transactional
    public void testIsolation() {
        testRTJPAService.deleteAll();
        TestRTJPA testRTJPA = new TestRTJPA();
        testRTJPA.setTitle("List of Acer gaming laptops");
        testRTJPA.setContent("Predator Helios Nitro");
        testRTJPA.setGid(150);
        int n = testRTJPAService.save(testRTJPA);
        assertEquals(1, n);

        List<TestRTJPA> testRTList = testRTJPAService.findMatched("List of Acer");
        assertEquals(1, testRTList.size());
        assertEquals("List of Acer gaming laptops", testRTList.get(0).getTitle());
    }

The test will fail (because of the overly isolated).

So I think setting Manticore transaction isolation level default to "READ-COMMITTED" is acceptable， but this needs to be made explicit in the documentation.

sanikolaev · 2023-11-28T05:45:51Z

how can I set the Manticore transaction isolation level by the command line

Manticore doesn't support isolation levels. We can only try to mock that, i.e.

SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED should not fail which is already ok
SELECT @@session.tx_isolation should return READ-COMMITTED or perhaps just not <empty>

Can you try the latest dev version? I see it the select returns 0 there unlike the latest release:

Tried the latest dev version. The error is:

java.sql.SQLException: Could not map transaction isolation '0' to a valid JDBC level.

From the analysis here, we know that @@session.tx_isolation must be a specific string, just like in mysql (here is the output of MySQL 8):

mysql> select @@session.transaction_isolation;
+---------------------------------+
| @@session.transaction_isolation |
+---------------------------------+

I was trying to use manticore with spring data JPA, but Hikari-cp was unable to establish connection witn manticore instance. Probably manticore is returning some empty string to hikari-cp while creating a connection, I have attached log traces below.

The exception

java.lang.NumberFormatException: For input string: "<empty>"

indicates that mysql_version_string is not set or the value is incorrect, see Notes on MySQL connectors.

However, after solving this problem, Manticore still cannot work on Spring boot's default data source. See this project for a workarround solution.
