Feature Description
Controls whether to enable or disable the crash detection feature.
After this feature is enabled, each TDStore node will establish a persistent connection with all other TDStore nodes. If the persistent connection is interrupted and several retries fail, the remote TDStore node will be considered down. At this point, the downtime callback will be triggered to perform some cleanup work (such as releasing residual participant contexts).
The negative impact of enabling this feature is that, when node pressure is very high, it may theoretically cause connection interruptions, thus posing risks of killing transactions by mistake. In addition, if the number of nodes is particularly large, it will also lead to an increase in the number of connections.
