i have xml looks this: <root> <header> ... </header> <entries> ... </entries> </root> there single header node, lot of entries. there way extract node java bean, without reading whole xml file. if possible, there support in springbatch or xstream? i don't think using springbatch chunk-oriented tasklet staxeventitemreader appropriate since want read 1 item. you can write own itemreader extending staxeventitemreader (or, better, delegating it), redefine method itemreader.read() , change condition indicate reader "exhausted" returning null after first valid node read: when spring-batch found itemreader.read() method returning null stop processing file. can use chunk-oriented , avoid full file read.

i'm trying plan new database-environment scratch , i'm wondering how many servers needed , how performance should provide. since want fast, i'm considering using ssd-memory , loads of ram. however, flash-memory expensive , makes biggest part of cost of server. thus, entire system should set horizontal scaling start, can add more nodes when need more storage/performance. to started i'm thinking of using 2 shards, each consisting of master , replica-slave redundancy. mongodb-documentation suggests using 1 master , 2 slaves, i'm afraid won't in available budget, since each of these servers equipped 200 gb of ram , 6x400 gb ssd raid 10. when using shards, suggested using 3 config-servers failsafe/high-availability. same above, i'm thinking 1 master , 1 slave start. what sort of hardware recommend put config-servers on? should equally performant shard-nodes in terms of cpu/memory/harddisk? or can put them on virtualization or on cheaper hardware? do...

someone explain me when gmap javascript api calls mapsbackend.loadmap method reported in google api console? is called when first script google using " http://maps.googleapis.com/maps/api/js?key= ..." url? called when gmap objects dynamically loaded google server? or called when map rendered on screen? (in case, method never called if map container tag display: hidden or display: none ?) thanks in advance each time create google.maps.map -instance map-load counted. from docs : a map load counted when map initialized on web page i've tested little bit, seems map-load counted first time when tilesloaded-event of map fires. this event fire when map hidden, when map-div isn't part of document @ all. it not fire when 1 of required arguments constructor missing(e.g. zoom), set required property tilesloaded-event fire , load counted.
