Abstract
Official abstract text for this publication.
A computer-implemented method for offloading extensible markup language (XML) data to a distributed file system may include receiving a command to populate a distributed file system with an XML table of a database. The XML table may be queried in response to the command. The source data in the XML table may be offloaded, by a computer processor, to the distributed file system in response to the querying. The offloading may include converting the source data to a string version of the source data and converting the string version of the source data back into XML format.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method for offloading extensible markup language (XML) data to a distributed file system, comprising: receiving a command to populate a distributed file system with an XML table of a database; querying the XML table in response to the command; offloading, by a computer processor, source data in the XML table to the distributed file system in response to the querying; receiving an XML path language (XPath) query against the XML table in the database; processing the XPath query based on the source data in the distributed file system to generate a result data; and storing the result data on the distributed file system in response to the XPath query. 2. The computer-implemented method of claim 1 , wherein the database is a DB2 database and the distributed file system is Hadoop Distributed File System (HDFS), and wherein the processing the XPath query based on the source data in the distributed file system to generate the result data comprises use of MapReduce functionality. 3. The computer-implemented method of claim 2 , further comprising: receiving a DB2 user-defined function to retrieve the result data; and storing the result data to the DB2 database in response to the DB2 user-defined function. 4. The computer-implemented method of claim 2 , further comprising: receiving a request for the result data from the DB2 database; and storing the result data to the DB2 database responsive to the request. 5. The computer-implemented method of claim 2 , wherein the offloading is performed by a BigInsights server. 6. The computer-implemented method of claim 2 , wherein the offloading is performed by a server for the DB2 database. 7. The computer-implemented method of claim 1 , wherein the offloading comprises converting the source data to a plain text version of the source data and converting the plain text version of the source data back into XML, format.
