sql server - Compressing headers -


we're using nservicebus 4.6 sql server transport (2012). sql server database set high availability using availability groups.

our dbas complaining amount of "churn"a have happening in transport database, , load placing on our wan.

we using xml serialization, started looking @ other serialization options available (would favour json it's still readable). however, in starting this, i've realised our message bodies typically between 600 , 1000 bytes, whereas our message headers regularly in range of 1200 - 1800 bytes1. so, if achieve great saving in terms of body sizes, it's not going produce large scale improvements i'm looking for.

the question

given, understand it, headers don't have readable when messages stored in sql server database, there way can compress them?

or other strategies reduce amount of data we're adding , deleting database? (whilst staying on nsb 4.6 now)

1we adding few custom headers ourselves metadata doesn't belong in message classes.

asince every message @ least goes queue table, removed table , placed in audit table, before later remove older audit entries, , we've got lot of messages, we're putting lot in sql server transaction log.

you can compress , decompress messages content via mutator. mutator example based on compressing message, should easy solution part:

http://docs.particular.net/samples/messagemutators/#code-walk-through-transportmessagecompressionmutator

you can add code same headers, compressing custom attributes before writing them , decompressing them before reading them.

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
