     Here is a short, but nice socket tutorial.

     You have to distinguish the client and server side. I cannot tell for MySQL, but typically the server side is implemented so, that for a connection, a new thread is processing the requests.

     A connection pool is there to minimize socket opening overhead. Typically, you do not care via which connection (assuming all connected as the same user); you received the result set from database.

     You do not want to consume resources, so you want to be nice and when you are finished you close your connection. I believe every server today ends a connection if there isn't any activity for some time (timeout).

     I have no clue about Go, but I can read the documentation, which suggests that you need to use this:

     root:root@tcp(newserver)/metro-

     Or possibly:

     mysql://root:root@tcp(newserver)/metro-

   • What is wrong with this Database connection string?

     Top Answer

     Answered Dec 19, 2012 · 10 votes

     Order of your parameter is wrong, it should be:

     db_server, db_Name, db_User, db_Pass-

     Currently it is:

     "server = {0}; database = {1}; uid = {2}; pwd = {3}" db_Server db_User db_Pass db_Name

     So your statement should be:

     MySqlConnection myConnection = new MySqlConnection(string.Format("server = {0}; database = {1}; uid = {2}; pwd = {3}", db_Server,db_Name, db_User, db_Pass));

     EDIT: based on the comments and discussion, the error you are getting is that you are trying all the stuff at class level. You should have these lines inside a method and call that method where you need it. Something like:

     class MyClass{ string db_Server = "10.0.0.0"; string db_User = "myUser"; string db_Pass = "myPassword"; string db_Name = "myDatabase"; public MySqlConnection GetConnection() { MySqlConnection myConnection = new MySqlConnection(string.Format( "server = {0}; database = {1}; uid = {2}; pwd = {3}", db_Server, db_Name, db_User, db_Pass)); return myConnection; }}

     There is a known bug which causes problems with jdbc connections using hostnames. Try using an Ip address instead.

   • What is the best solution for database connection pooling in python?

     Top Answer

     Answered Nov 19, 2020 · 16 votes

     IMO, the "more obvious/more idiomatic/better solution" is to use an existing ORM rather than invent DAO-like classes.

     It appears to me that ORM's are more popular than "raw" SQL connections. Why? Because Python is OO, and the mapping from a SQL row to an object is absolutely essential. There aren't many use cases where you deal with SQL rows that don't map to Python objects.

     I think that SQLAlchemy or SQLObject (and the associated connection pooling) are the more idiomatic Pythonic solutions.

     Pooling as a separate feature isn't very common because pure SQL (without object mapping) isn't very popular for the kind of complex, long-running processes that benefit from connection pooling. Yes, pure SQL is used, but it's always used in simpler or more controlled applications where pooling isn't helpful.

     I think you might have two alternatives:

     • Revise your classes to use SQLAlchemy or SQLObject. While this appears painful at first (all that work wasted), you should be able to leverage all the design and thought. It's merely an exercise in adopting a widely-used ORM and pooling solution.
     • Roll out your own simple connection pool using the algorithm you outlined -- a simple Set or List of connections that you cycle through.

     In MySQL?

     I'd say don't bother with the connection pooling. They're often a source of trouble and with MySQL they're not going to bring you the performance advantage you're hoping for. This road may be a lot of effort to follow--politically--because there's so much best practices hand waving and textbook verbiage in this space about the advantages of connection pooling.

     Connection pools are simply a bridge between the post-web era of stateless applications (e.g. HTTP protocol) and the pre-web era of stateful long-lived batch processing applications. Since connections were very expensive in pre-web databases (since no one used to care too much about how long a connection took to establish), post-web applications devised this connection pool scheme so that every hit didn't incur this huge processing overhead on the RDBMS.

     Since MySQL is more of a web-era RDBMS, connections are extremely lightweight and fast. I have written many high volume web applications that don't use a connection pool at all for MySQL.

     This is a complication you may benefit from doing without, so long as there isn't a political obstacle to overcome.

     Wrap your connection class.

     Set a limit on how many connections you make. Return an unused connection. Intercept close to free the connection.

     Update: I put something like this in dbpool.py:

     import sqlalchemy.pool as poolimport MySQLdb as mysqlmysql = pool.manage(mysql)
