+Synopsis
+--------
+
+This folder contains a service recipe for MySQL.
+
+Its default port is 3306, but it can be modified in the mysql-service.properties.
+
+You can inherit and extend this recipe very easily, just by changing the mysql-service.properties file, without changing even one line of code in the recipe.
+
+This is achieved thanks to the following  : 
+
+1.	A Start Detection Query
+In most of our recipes, we use something like : ServiceUtils.isPortOccupied(port).
+In this case, it is usually NOT enough, because the port just means that the DB is up, but we also need the schema to be ready.
+So I added a startDetectionQuery property (to the properties file) in which you can insert an SQL query.
+The service instance is alive only if the port is occupied AND the startDetectionQuery result is true.
+
+2.	Post Start Actions : 
+In the properties file you can insert an array of postStart commands (as many commands as you want).
+These post start commands will be invoked during the... postStart lifecycle event.
+There are four types of postStart commands : 
+a)	mysqladmin: for invoking any administrative command ( for example : creating a new DB ) 
+b)	mysql : for invoking any SQL statement: insert, update, grant permissions etc.
+c)	import : for importing a DB schema ( by providing a full URL of the zip file that contains the schema )
+d)  mysqldump : for creating a db dump (snapshot)
+
+ActionType can be one of the four following: mysqladmin,mysql,mysqldump or import
+   Examples :
+
+   // In this case, dbName is a property which is defined in this properties file 
+   // All the occurrences of MYSQLHOST in actionQuery, will be replaced with the private IP address on which this service instance resides   
+   [  
+		"actionType" : "mysqladmin", 
+		"actionQuery" : "create" ,
+		"actionUser"  : "root",
+		"actionDbName" : "${dbName}",
+		"debugMsg" : "Creating db - Name  : ${dbName} ... "
+	] ,
+
+
+	// In this case, dbUser and dbPassW are properties which are defined in this properties file 
+   // All the occurrences of MYSQLHOST in actionQuery, will be replaced with the private IP address on which this service instance resides	
+	[ 
+		"actionType" : "mysql", 		
+		"actionQuery" : "\"CREATE USER '${dbUser}'@'localhost' IDENTIFIED BY '${dbPassW}';\"",
+		"actionUser"  : "root",
+		"actionDbName" : "${dbName}",
+		"debugMsg" : "Creating db user ${dbUser} at localhost, passw ${dbPassW} in ${dbName} db... " 
+	],
+
+   // In this case:
+   //    dbName,currDBZip,currImportSql are properties which are defined in this properties file 
+   //    currDBZip is the local name of the zip file ( after download )  
+   //    currImportSql is the name of the sql file which is stored in currDBZip. 
+   /     All the occurrences of REPLACE_WITH_DB_NAME in currImportSql, will be replaced with ${dbName}
+   [ 
+		"actionType" : "import", 
+		"importedZip" : "${currDBZip}",
+		"importedFile" : "${currImportSql}",
+		"importedFileUrl" : "http://dropbox/1/222/mysql.zip",
+		"actionUser"  : "root",
+		"actionDbName" : "${dbName}",
+		"debugMsg" : "Importing  to ${dbName} ..."
+	]	
+
+   // In this case:
+   //    dbName is a property which is defined in this properties file.
+   //    if actionDbName is an empty string,  then --all-databases will be used
+   //    actionArgs contain the flags that you want to use with this mysqldump command
+   //    Do NOT database flags, because they will be set according to the actionDbName.
+   //    So do NOT use the following  : --all-databases,-A,--databases
+   //    Do NOT -u flag flags, because it will be set according to the actionUser
+   [ 
+		"actionType" : "mysqldump", 
+		"actionArgs" : "--add-drop-database -c --lock-all-tables -F",
+		"actionUser"  : "root",
+		"actionDbName" : "${dbName}",
+		"dumpPrefix" : "myDumpFile_",
+		"debugMsg" : "Invoking mysqldump ..." 
+	]	
+
+
+
+
+## Custom Commands 
+
+#mysqldump - This custom command enables users to create a database snapshot (mysqldump).
+
+Usage :  <strong>invoke mysql mysqldump actionUser dumpPrefix [dbName]</strong>
+Example: <strong>invoke mysql mysqldump root myPrefix_ myDbName</strong>
+
+#query - This custom command enables users to invoke an SQL statement.
+
+Usage :  <strong>invoke mysql query actionUser dbName query</strong>
+
+Examples 
+
+1. If you want to update the users table in myDbName with the following statement : 
+<strong>update users set name='James' where uid=1</strong>
+   - then you need to run the following custom command : 
+<strong>invoke mysql query root myDbName \\"update users set name=\\'James\\' where uid=1\\"</strong>
+
+2. If you want to insert a new user named Dan, into the users table in myDbName, and you need the following SQL statement:
+<strong>INSERT INTO users VALUES (17,'Dan','hisPassword','hisemail@his.com',0)</strong>
+  - then you need to run the following custom command : 
+<strong>invoke mysql query root tamirDB \\"INSERT INTO users VALUES \\(17,\\'Dan\\',\\'hisPassword\\',\\'hisemail@his.com\\',0\\)\\"</strong>
