Techniques for more efficient generation of XML events from XML data sources

A method comprising:

• based on one or more characteristics of a plurality of XML data sources, determining a memory size for an XML event-generating process to process said plurality of XML data sources;
• prior to processing the plurality of XML data sources using the XML event-generating process, requesting, from a memory manager, allocation of a memory chunk of the memory size for use with the XML event-generating process;
• processing the plurality of XML data sources using the XML event-generating process, thereby generating one or more XML events, wherein processing the plurality of XML data sources comprises:
• wherein, for each particular XML data source of the plurality of XML data sources, processing the particular XML data source requires the use of at least one memory buffer;
• and
• the XML event-generating process creating without calling the memory manager, each memory buffer required for processing the plurality of XML data sources in the same previously allocated memory chunk;
• upon completion of processing the plurality of XML data sources, requesting that the memory manager deallocate the memory chunk;
• wherein the method is performed by one or more computing devices.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more computing devices, cause performance of steps comprising:

• based on one or more characteristics of an XML data source, determining a memory size for an XML event-generating process to process said XML data source;
• prior to processing the XML data source using the XML event-generating process, requesting, from a memory manager, allocation of a memory chunk of the memory size for use with the XML event-generating process;
• processing the XML data source using the XML event-generating process, thereby generating one or more XML events, wherein processing the XML data source comprises:
• the XML event-generating process determining that processing the XML data source requires the use of a plurality of memory buffers;
• and
• the XML event-generating process creating the plurality of memory buffers in the previously allocated memory chunk, without calling the memory manager;
• and
• after processing the XML data source, requesting that the memory manager deallocate the memory chunk.
