Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures associated with the present application are shown in the drawings, not all of them.
Example one
Fig. 1 is a schematic flow diagram of a LDAP-based memory management method according to an embodiment of the present application, which is described in this embodiment from a first platform side. The method can be executed by an LDAP-based memory management device, which can be implemented in hardware and/or software, and can be generally integrated into a computer or other electronic device with data operation capability, and specifically includes the following steps:
In this embodiment, because some programs or data entries need to be cached by using a memory for data operation on the LDAP database, the memory is used for matching data operation on the LDAP database, and provides a memory storage service during the data operation.
In this step, the operation type of the data operation may be various, and in a specific embodiment, the target operation type of the data operation is one of the following operation types: adding operation, deleting operation, changing operation and checking operation.
The adding operation refers to adding data entries into the LDAP database, the deleting operation refers to deleting some data entries from the LDAP database, the changing operation refers to modifying the data entries in the LDAP database, and the searching operation refers to searching the required data entries from the LDAP database.
Specifically, in this step, when determining the target operation type to which the data operation belongs, the target operation type to which the data operation belongs may be determined according to the received data operation instruction, and usually, the data operation instruction may include some key program instructions, and these program instructions are usually fixed, so that the target operation type to which the data operation belongs may be determined by identifying the operation type corresponding to the program instruction.
And 102, determining a target memory operation strategy corresponding to the target operation type according to a preset mapping relation between the operation type and the memory operation strategy.
In this step, the mapping relationship may be embodied in a program instruction, that is, after the target operation type is identified, the mapping relationship may enter a corresponding memory operation program, where the memory operation program is referred to as the target memory operation policy in this step.
Therefore, the process of determining the target memory operation policy corresponding to the target operation type in this step can be implemented by corresponding program codes, such as common IF statements and the like.
And 103, performing data operation in the entry space, the entry information space and the index space of the memory based on the target memory operation strategy to provide memory storage service when performing data operation on the LDAP database.
It should be noted that the entry space, the entry information space, and the index space of the memory in this step may be spaces pre-partitioned from the memory, and as a mechanism of a Lightweight Directory Access Protocol (LDAP) mainly sets a unit of data as an entry, the entry is to be stored on a server as a data unit, and a unit of a memory management mechanism is also an entry. LDAP optimizes the items to form a tree structure for searching and inquiring, so the LDAP has excellent inquiring performance, and the LDAP is used as a protocol, and simultaneously defines calling rules and calling modes, standardizes the use of a database and provides better guarantee for data security.
Therefore, in order to accommodate LDAP, the present embodiment divides an entry space, an entry information space, and an index space from a memory. The item space is used for storing a data item structure, which can be used as a temporary storage and a provider of the query result, and therefore, the item space needs to occupy a larger space. In order to prevent the memory space from being insufficient, the embodiment may apply a certain amount of memory space as the entry space when the system is started.
In addition, the entry information space is used for storing entry information, the entry information is used for providing a convenient and fast mode for operation, and the speed of using the data entry during calling and operation is reduced due to the fact that the memory space occupied by one data entry is large, so that the key information of the data entry is extracted and stored as the entry information, and the entry information is directly used during subsequent calling and operation, so that the calling and operation speed can be increased.
It should be noted that the key information extracted may be some common attributes of the data items.
The index space in this step is used to store the index information of the data entry, and under the LDAP protocol, the index information of the data entry may be related, so that the present embodiment also sets the index space in the memory to store the corresponding index information, and may provide an index directory for the subsequent search operation.
The purpose of performing memory management in this embodiment is to better divide the memory space, use a smaller memory space, process a larger amount of data, and use a smaller cost to improve the performance of the LDAP database. In order to determine the size of each space, setting the size of the space in a configuration file of an LDAP database, wherein the entry space corresponds to a cachesize attribute in the configuration file, and the unit is an entry; the entry information space corresponds to the dncesize attribute of the configuration file, and the unit is an entry; the index space corresponds to the idlcesize attribute of the configuration file, with the unit being an entry, and examples of configuration files are as follows:
cachesize 1000000 # entries space size 1000000 entries;
the information space size of the dncesize 1000000 # entries is 1000000 entries;
idlcesize 1000000 # index space size is 1000000 entries.
Further, in this step, when the target operation type is an add operation, the process of performing data operation in the entry space, the entry information space, and the index space of the memory based on the target memory operation policy may be:
after data is added to a disk of an LDAP database, the added data items are obtained from a memory; extracting key information of the data entry to obtain entry information, and storing the entry information into an entry information space of a memory; and adding the acquired data entries into an entry space of the memory, and adding entry indexes of the data entries into an entry index space of the memory.
It should be noted that, the process of refining the key information of the data entry is to extract the preset attribute in the data entry as the key information. Because newly added data is generally more likely to be queried, corresponding information of newly added data entries can be stored in an entry space, an entry information space and an index space in the memory, so that the newly added data entries can be directly acquired from the memory during subsequent query, and the query rate is improved to a certain extent.
In addition, in this step, when the target operation type is a delete operation, the process of performing data operation in the entry space, the entry information space, and the index space of the memory based on the target memory operation policy may be:
after deleting data from a disk of an LDAP database, searching whether an entry index to be deleted corresponding to the deleted data exists in an entry index space of a memory; if the data entry exists, deleting the entry index to be deleted in the entry index space, deleting the entry information to be deleted corresponding to the entry index to be deleted in the entry information space of the memory, and deleting the data entry to be deleted corresponding to the entry index to be deleted in the entry information space of the memory.
Since the corresponding data is deleted from the LDAP database, the data is not subsequently queried, that is, the data is not needed, and therefore, in order to save the memory space, the data entry is deleted synchronously in the entry space, the entry information space, and the index space of the memory.
In this step, when the target operation type is a change operation, the process of performing data operation in the entry space, the entry information space, and the index space of the memory based on the target memory operation policy may be:
after the attribute modification is carried out on the data entry to be modified in the disk of the LDAP database, whether an entry index to be modified corresponding to the data entry to be modified exists in an entry index space of a memory is searched; if the data item exists, searching the information of the item to be modified according to the index of the item to be modified, and searching the corresponding data item to be modified from the item space of the memory through the information of the item to be modified; and modifying the attribute of the data entry to be modified in the entry space of the memory.
It should be noted that, because the modification operation involves modifying the attribute, and the refined entry information also consists of the attribute, this embodiment can determine whether the attribute to be modified is the key information in the entry information to be modified; and modifying the key information in the item information to be modified based on the modified attribute under the condition that the attribute to be modified is the key information in the item information to be modified.
In addition, in this step, when the target operation type is a lookup operation, the process of performing data operation in the entry space, the entry information space, and the index space of the memory based on the target memory operation policy may be:
searching whether a target entry index meeting the searching condition in the data operation exists in an index space of a memory; if yes, searching corresponding target entry information from the entry information space through the target entry index, mapping the target entry information to a target data entry of the entry space, and feeding back the target data entry serving as a query result; if not, searching a target data item meeting the searching condition in the data operation from a disk of the LDAP database; extracting key information of the target data entry to obtain target entry information, and storing the target entry information into an entry information space of a memory; and adding the target data entry into the entry space of the memory, and adding the target entry index of the target data entry into the entry index space of the memory.
When the data operation of the search operation is performed, since the previous increment operation and the search operation may pre-store the data entry to be queried by the data operation corresponding to the current search operation in the memory, it may be first queried whether the data entry exists in the memory. If the data exists, the feedback is directly carried out, and the data reading and writing speed of the memory is high, so that the query efficiency is improved to a certain extent.
In addition, after a certain data entry is queried, multiple queries are usually performed on the data entry in a short time, so that if the data does not exist in the memory, after the data entry is found from the LDAP database, the data entry, corresponding entry information and index information can be stored in a corresponding space, thereby facilitating subsequent re-queries.
In the embodiment, under the condition that the data operation needs to be performed on the LDAP database, the target operation type to which the data operation belongs is determined; determining a target memory operation strategy corresponding to the target operation type according to a preset mapping relation between the operation type and the memory operation strategy; and performing data operation in the entry space, the entry information space and the index space of the memory based on the target memory operation strategy so as to provide memory storage service when performing data operation on the LDAP database. Based on this, in this embodiment, the memory space is divided according to the LDAP protocol, the entry space, the entry information space, and the index space are determined, then different memory operation policies are set for different operation types of data operations, so as to provide a memory storage service for the data operations performed on the LDAP database, and different spaces are set, and the different spaces are adapted to the LDAP protocol and are matched with the LDAP database, so that the efficiency of the data operations is higher, and the space utilization rate of the memory is also higher.
