Detailed Description

InnoDB Memcached Engine code

Extracted and modified from NDB memcached project 04/12/2011 Jimmy Yang

Definition in file innodb_engine.c.

Macro Definition Documentation

#define BK_COMMIT_THREAD_SLEEP_INTERVAL   5

Time (in seconds) that background thread sleeps before it wakes

up and commit idle connection transactions

Definition at line 49 of file innodb_engine.c.

#define BK_MAX_PROCESS_COMMIT   5

Maximum number of connections that background thread processes each

time

Definition at line 53 of file innodb_engine.c.

#define CONN_IDLE_TIME_TO_BK_COMMIT   5

Minimum time (in seconds) that a connection has been idle, that makes

it candidate for background thread to commit it

Definition at line 57 of file innodb_engine.c.

#define KEY_MAX_LENGTH   250

Define also present in daemon/memcached.h

Definition at line 45 of file innodb_engine.c.

Typedef Documentation

typedef struct eng_config_info eng_config_info_t

InnoDB Memcached engine configuration info

Enumeration Type Documentation

enum conn_mode

Defines for connection initialization to indicate if we will

do a read or write operation, or in the case of CONN_MODE_NONE, just get the connection's conn_data structure

Definition at line 682 of file innodb_engine.c.

Function Documentation

ENGINE_ERROR_CODE create_instance	(	uint64_t	interface,
		GET_SERVER_API	get_server_api,
		ENGINE_HANDLE **	handle
	)

Create InnoDB Memcached Engine.

Returns

ENGINE_SUCCESS if successful, otherwise, error code

Parameters

interface	in: protocol version, currently always 1
get_server_api	in: Callback the engines may call to get the public server interface
handle	out: Engine handle

Definition at line 145 of file innodb_engine.c.

void handler_close_thd

(

void *

my_thd

)

Close the handler

Parameters

my_thd

in: THD

Definition at line 360 of file handler_api.cc.

Here is the call graph for this function:

int handler_unlock_table	(	void *	my_thd,
		void *	my_table,
		int	mode
	)

Check the input key name implies a table mapping switch. The name

would start with "@@", and in the format of "@@new_table_mapping.key" or simply "@@new_table_mapping" Unlock a table and commit the transaction return 0 if fail to commit the transaction in: lock mode

Unlock a table and commit the transaction return 0 if failed to commit the transaction

Parameters

my_thd	in: thread
my_table	in: Table metadata
mode	in: mode
