All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be understood that the step numbers used herein are for convenience of description only and are not intended as limitations on the order in which the steps are performed.
It is to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
The terms "comprises" and "comprising" indicate the presence of the described features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
The term "and/or" refers to and includes any and all possible combinations of one or more of the associated listed items.
In a first aspect:
referring to fig. 1, an embodiment of the present invention provides an unstructured data federation storage method, including:
s10, establishing a federal node unique identification code specification;
s20, establishing a federal node access specification according to the code of the unique identifier of the federal node;
s30, registering the specification information of the Federal node access specification to a registration center, and acquiring the brevity code returned by the registration center;
And S40, generating id for the object entity stored on the federal node according to the brevity code and the object id generation specification.
In this embodiment, it should be noted that the unstructured data object storage technology is a basic unit for storing a storage object, a bucket is a container for storing the storage object, each bucket has attributes such as its storage category and access right, and the bucket can be located by an access domain name of the bucket on the internet. The mainstream storage mode of unstructured data at present is an hdfs system that stores unstructured data by using a hadoop cluster. However, this method needs to write data block by block, so the storage process is very slow and inefficient, and the throughput of the whole HDFS file system is limited by the throughput of a single NameNode, which becomes the performance bottleneck of HDFS. Therefore, the present embodiment mainly intends to provide an efficient data storage method.
Specifically, a federal node unique identification code specification is established in step S10; it should be noted that the unique identifier name of the federate node is named in a form of a geographical space location name abbreviation plus a numerical sequence number where the storage server is located, wherein the naming structure is as follows: "national-province-city-machine room serial number-cluster serial number". For example, the unique identifier of the unstructured storage cluster established in the patrol No. 1 machine room of Zhaoqing city, Guangdong province, China is as follows: "cn-gd-zq-jx 01-01".
Further, a federal node access specification is established in step S20; when the federal node accesses the federal registration center, the node must provide the following information, including: the unique identification code of the federal node, the main access domain name or vip, the standby access domain name or vip, the type of the accepted service and the information of whether the reading function is open or not.
Next, at S30, the information of the federal node access specification is used to register in the registry, and the brevity code returned by the registry is obtained.
In this embodiment, a registry of the federation cluster is preferably constructed by adopting a zookeeper cluster with three nodes, each federation node registers the specification information agreed in the step S20 to the registry through a registry http service, and obtains a brevity code returned by the registry. The brevity code is globally unique in a registration center and corresponds to the federal nodes one by one; the abbreviated code format is full alphabetic, all-digital, or a combination of alphanumeric. For example: and the unique identifier of the federal node is 'cn-gz-zq-jx 01-01', and the brevity code is's 001' after the registration is successful.
In one embodiment, the federal node needs to poll for renewal at a preset period, for example, once every 2 seconds; if no renewal is made, the registry marks the federated node down-line and does not respond to any object store and read requests. It is understood that the polling duration of 2 seconds is only a preferred mode of the embodiment, and in practical applications, the preset period can be selected according to requirements, and is not limited herein.
In a certain embodiment, the registration center can set polling weights for the federal nodes registered in the center, and the polling weights are used for shunting and regulating the response pressure of each federal node.
And S40, generating id for the object entity stored on the federal node according to the brevity code and the object id generation specification.
Upon receiving the brevity code in step S30, step S40 primarily implements data storage and generates a canonical id for the object entity. The generation specification of the federal node object id is as follows: when the object entity is stored in the federal node, the node generates a uuid, and takes the node brevity code input parameter issued by the receiving registration center as a primary key suffix, and the node brevity code input parameter is spliced into a unique id by means of "-" segmentation, and the unique id is used as a unique identifier of the object stored in the node.
For example: when a picture is stored in the federal node with s001 brevity code, the issued component id is "756 d19c3f07b-812e5a1cd83eac702bb6-s 001".
In one embodiment, the unstructured-data federated storage method further includes: and establishing a federal node access gateway to realize the forwarding of the federal access request.
It should be noted that, when the object storage request reaches the gateway layer, the gateway layer extracts the object entity and the service type information in the request, obtains the federal node information of all the objects receiving the service type modification in the registry, and polls and distributes the federal node information to one of the nodes according to the weight;
When the object reading request reaches the gateway layer, the gateway layer extracts the id information in the object request, obtains the federated node access address information from the registration center by segmenting the federated node brevity code at the end of the id, and forwards the request to the federated node of the actual service to complete the acquisition of the object entity.
The federated storage method provided by the invention has more efficient performance, can provide a plurality of NameNodes and provide services to the outside at the same time, has good expandability, can increase the storage capacity by adding new NameNodes and DataNodes, and can not influence the existing data while increasing the storage capacity, therefore, the data migration is not needed, and the storage of the cluster is conveniently and rapidly expanded.

Further, in the unstructured-data federal storage device provided in this embodiment, the federal node access specification includes: the method comprises the steps of unique identification codes of the federal nodes, main access domain names or vips, standby access domain names or vips, accepted service types and read function opening information.
Further, when the unstructured-data federated storage device provided in this embodiment executes the storage method, a federated node access gateway is also established to implement the forwarding of a federated access request.
When the object storage request reaches the gateway layer, the gateway layer extracts object entities and service type information in the request, acquires all federal node information of the objects which accept the service type change in the registration center, and polls and distributes the federal node information to one node according to the weight;
when the object reading request reaches the gateway layer, the gateway layer extracts the id information in the object request, obtains the federated node access address information from the registration center by segmenting the federated node brevity code at the end of the id, and forwards the request to the federated node of the actual service to complete the acquisition of the object entity.
Further, when the unstructured data federation storage device provided by the embodiment executes the storage method, polling renewal is performed according to a preset period through a federation node; if no renewal is made, the registry marks the federated node down-line and does not respond to any object store and read requests.
Further, when the unstructured-data federated storage device provided by this embodiment executes the storage method, a polling weight is also set by the registration center for a federated node that has registered in the center, so as to shunt and regulate the response pressure of each federated node.
