  decode msg from bytebuffer

  Posted by aele on May 16, 2024 at 5:42 pm

  Hi kx community,

  I am running to trouble while decoding msg from ByteBuffer.

  The background is that I am consuming live data from solace bus, with live data feed ingested into kdb+, it is not something could be directly cast into character. What I get with the attempt to cast from binary is code like:

  “\PAR1\025\004\025\010…”

  Could anyone enlighten me how to decode those without routing into a java parser with ByteBuffer?

  Thanks a lot.

  The is a kdb+ Solace interface

  • https://solace.com/kx/

  One of the getPayloadAs* functions may be what you need
