Embodiment one
The embodiment of the present invention one provides a kind of metadata storing method, referring to Fig.1, which comprises
The metadata operation that step 101, API Gateway receive the transmission of one or more file system client is asked
It asks；
In the step, API Gateway refers to application programming interface gateway.
In practical realization, metadata storage system applied by one the method for the embodiment of the present invention is as shown in Fig. 2, Fig. 2
In, API Gateway is provided between file system client and multiple Metadata Service ends, via API Gateway to text
The metadata operation request that part system client is sent carries out United Dispatching and forwarding, and to the processing that Metadata Service end returns
As a result it is transmitted to corresponding file system client.
Specifically, metadata operation request includes at least one in following request:
Increase file node information request, deletes file node information request, update file node information request, obtain text
The request of part nodal information, increase document structure information, which are requested, deletion document structure information is requested, update document structure information asks
It asks, obtain document structure information request, obtaining file root id request and obtain file node id request.
Step 102, API Gateway carry out authentication process to the metadata operation request received；
In the step, after API Gateway receives the metadata operation request of file system client transmission, docking
The metadata operation request received is unified to carry out authentication process.
Specific authentication processing method is: compare the username and password in metadata operation request, if user name and
Password is correct, then the authentication is passed；Otherwise, failed authentication.
Step 103, after the authentication is passed, request is diverted to corresponding Metadata Service end by API Gateway.
Metadata Service is managed using resource pool inside API Gateway, is asked for the metadata operation that the authentication is passed
It asks, API Gateway determines the service of current idle, and the service of current idle is distributed to authentication according to preset order and is led to
The metadata operation request crossed；It needs to wait if not idle service, until the service for having the available free time.Often
The corresponding Metadata Service end of one idle service, for the idle service of metadata operation request distribution, that is, referring to will be first
Data operation request is transmitted to Metadata Service end corresponding to the service of corresponding free time to be handled.
In a kind of optional embodiment of the invention, when the metadata operation request that the authentication is passed is multiple, API
Gateway can be according to the sequencing of the multiple metadata operation request transmission time, alternatively, according to the multiple first number
According to the priority of operation requests from high to low sequence, for the idle service of the multiple metadata operation request distribution.
And two kinds of situations are issued for bluish-green deployment and gray scale, the distribution of Metadata Service is carried out in the following ways:
1. the API Gateway is from the Metadata Service end for providing latest edition service when carrying out bluish-green deployment
Determine the Metadata Service end of current idle, and by the Metadata Service end for the current idle determined according to preset order
Distribute to the metadata operation request that the authentication is passed.
2. the API Gateway is from the Metadata Service end for providing latest edition service when carrying out gray scale publication
It determines the Metadata Service end of current idle, and determines default host name pair from the metadata operation request that the authentication is passed
The request of metadata operation transmitted by the file system client answered；
The Metadata Service end for the current idle for providing latest edition service determined is distributed according to preset order
It is requested to metadata operation transmitted by the corresponding file system client of default host name determined；By other free time
Other hosts are distributed to according to preset order in Metadata Service end (the Metadata Service end of original version service is namely provided)
Metadata operation request transmitted by the corresponding file system client of name.
It needs when carrying out gray scale publication by first number transmitted by file system client corresponding to specified host name
It is drained into the Metadata Service end that latest edition service is provided according to operation requests, and file system corresponding to other host name
Client is still split into the Metadata Service end for providing original version service.The specified host name can be according to any
Meet the algorithm of needs to be screened.
In the bluish-green deployment of progress and gray scale publication, when the preset order also refers to multiple metadata operations request transmissions
Between sequencing, alternatively, the priority of multiple metadata operations request is from high to low sequence.
Specific to bluish-green deployment, the multiple metadata operation request refers to that multiple metadata operations that the authentication is passed are asked
It asks；And issued specific to gray scale, the multiple metadata operation request refers to that the authentication is passed and its transmission client is default
Multiple metadata operations of the corresponding file system client of host name are requested, and may also mean that the authentication is passed and it sends visitor
Family end is not multiple metadata operations request of the default corresponding file system client of host name.
In a kind of optional embodiment of the invention, when not idle service, API Gateway can periodically be taken turns
The working condition for asking Metadata Service end, alternatively, reporting the sky of itself to API Gateway during idle time from Metadata Service end
Not busy state, so that API Gateway be enable to determine the Metadata Service end of current idle in time.
In a kind of optional embodiment of the invention, referring to Fig. 3, the method also includes following steps:
Step 104, API Gateway receive the processing result that Metadata Service end returns, and the processing result is first number
The processing result generated after handling according to server-side the metadata operation request received；
Specifically, the processing result include: processing whether successful identification information and file process relevant information.
The processing result is transmitted to corresponding file system client by step 105, API Gateway.
To sum up, metadata storing method provided by the embodiment of the present invention one, comprising: API Gateway receive one or
The metadata operation request that the multiple file system clients of person are sent；The API Gateway is to the metadata operation received
Request carries out authentication process；The metadata operation request that the authentication is passed is diverted to Metadata Service end by the API Gateway.
Technical solution provided by the embodiment of the present invention one at least has following advantages:
1, the utilization of resources of Metadata Service is greatly improved using Service Source pond by introducing API Gateway
Rate, and high concurrent client is reduced to the pressure of server-side.
2, due to having unified entrance, Metadata Service complexity and development cost are reduced；
3, the universal retrieval based on API Gateway improves entitlement efficiency；
4, the request shunting based on API Gateway can be realized load balancing control；
5, due to reducing the degree of coupling of file system client Yu Metadata Service end, it can very simple, side
Just bluish-green deployment and gray scale publication are completed.
