replayInterval Duration Delay between each replayed requests, in milliseconds 10 no
reconnectionDelay Duration number of milliseconds between reconnection attempts 1000 no

volatile VolatileData Common volatile data, will be sent to all future requests - no


  • if queueTTL is set to 0, requests are kept indefinitely
  • The offline buffer acts like a first-in first-out (FIFO) queue, meaning that if the queueMaxSize limit is reached, older requests are discarded to make room for new requests
  • if queueMaxSize is set to 0, an unlimited number of requests is kept until the buffer is flushed
  • multiple methods allow passing specific volatile data. These volatile data will be merged with the global Kuzzle volatile object when sending the request, with the request specific volatile taking priority over the global ones.

# Getter & Setter

The properties can be writable.
For example, you can read the volatile property via getVolatile() and set it via setVolatile().
