Use: "start",
Short: "Run the full node",
Long: `Run the full node application with Tendermint in or out of process. By
default, the application will run with Tendermint in process.
Pruning options can be provided via the '--pruning' flag or alternatively with '--pruning-keep-recent',
'pruning-keep-every', and 'pruning-interval' together.
For '--pruning' the options are as follows:
default: the last 100 states are kept in addition to every 500th state; pruning at 10 block intervals
nothing: all historic states will be saved, nothing will be deleted (i.e. archiving node)
everything: all saved states will be deleted, storing only the current state; pruning at 10 block intervals
custom: allow pruning options to be manually specified through 'pruning-keep-recent', 'pruning-keep-every', and 'pruning-interval'
Node halting configurations exist in the form of two flags: '--halt-height' and '--halt-time'. During
the ABCI Commit phase, the node will check if the current block height is greater than or equal to
the halt-height or if the current block time is greater than or equal to the halt-time. If so, the
node will attempt to gracefully shutdown and the block will not be committed. In addition, the node
will not be able to commit subsequent blocks.
For profiling and benchmarking purposes, CPU profiling can be enabled via the '--cpu-profile' flag
which accepts a path for the resulting pprof file.
