It looks like it might be knobs (which can be changed via config file) called MAX_WRITE_TRANSACTION_LIFE_VERSIONS and MAX_READ_TRANSACTION_LIFE_VERSIONS now (defined in ServerKnobs.cpp)? It's in microseconds and probably needs to be synced client and server.
I don't know the details know, but it was definitely configurable when I wrote it :) I remember arguing for setting it to a default of 30/60 seconds we decided against as that would have impacted throughput at our default RAM budget. I thought might have been a good tradeoff to get people going, thinking they could tune it down (or up the RAM) if they needed to scale up perf later.
