US 2014/0279825 A1 · EXTENSIBILITY MODEL FOR DOCUMENT-ORIENTED STORAGE SERVICES

Abstract

A document service may be provided by many document service packages, each presenting a particular set of service characteristics (e.g., the performance achievable on various storage device types; the available indexing models; and the types of transactions, scripts, and queries supported by the document service). For a particular project, an administrator may endeavor to select a document service package exhibiting characteristics that match some criteria of the project and to configure or adapt the document service for other criteria, but the range of adaptability for each document service package may be limited. Presented herein are architectures for document services involving a composable set of components respectively providing a service feature with a service characteristic. The document service may be automatically composed by, for each service feature of the document service, selecting a service component for the service feature that matches the service criteria specified in a service level agreement.

Dependent claims

A method of configuring a server to provide a document service on a device having a processor, the method comprising:

executing on the processor instructions configured to:
for respective service features of the document service, provide at least two candidate components respectively providing the service feature with at least one service characteristic;
and
upon receiving a request to provide the document service according to a service level agreement specifying, for respective service features, at least one service criterion:
for respective service features, among the candidate components for the service feature, identify a selected service component providing the service feature with service characteristics satisfying the at least one service criterion specified by the service level agreement for the service feature;
and
compose the selected service components to provide the document service.

A document service provided on a server having a memory and a processor, the document service comprising:

for respective service features of the document service, at least two candidate components respectively providing the service feature with at least one service characteristic, the service features including:
a file system interface provided by at least two file system components respectively configured to access documents of the document service according to a file system schema exhibiting at least one file system performance characteristic;
an indexing interface provided by at least two indexing components respectively configured to index documents of the document service according to a document indexing technique exhibiting at least one indexing characteristic;
a transaction interface provided by at least two transaction components respectively configured to apply transaction requests to at least one document of the document service according to a transaction model exhibiting at least one transaction characteristic;
a replication interface provided by at least two replication components respectively configured to replicate the document service over at least two servers according to a replication model exhibiting at least one replication characteristic;
a query interface provided by at least two query engine components respectively configured to apply queries to the document service according to a query model exhibiting at least one query model characteristic;
a scripting interface provided by at least two scripting environment components respectively configured to execute scripts in a script language against the document service according to a scripting environment exhibiting at least one scripting characteristic;
and
a security interface provided by at least two security components respectively configured to apply to the document service a security model exhibiting at least one security characteristic;
and
a document service component selector comprising instructions stored in the memory that, when executed on the processor, compose the document service by:
upon receiving a request to provide the document service according to a service level agreement specifying, for respective service features, at least one service criterion:
for respective service features, among the candidate components for the service feature, identifying a selected service component providing the service feature with service characteristics satisfying the at least one service criterion specified by the service level agreement for the service feature;
and
composing the selected service components to provide the document service.
