okp4d start
Run the full node
Synopsis
Run the full node application with CometBFT in or out of process. By default, the application will run with CometBFT in process.
Pruning options can be provided via the '--pruning' flag or alternatively with '--pruning-keep-recent', and 'pruning-interval' together.
For '--pruning' the options are as follows:
default: the last 362880 states are kept, pruning at 10 block intervals nothing: all historic states will be saved, nothing will be deleted (i.e. archiving node) everything: 2 latest states will be kept; pruning at 10 block intervals. custom: allow pruning options to be manually specified through 'pruning-keep-recent', 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.
The node may be started in a 'query only' mode where only the gRPC and JSON HTTP API services are enabled via the 'grpc-only' flag. In this mode, CometBFT is bypassed and can be used when legacy queries are needed after an on-chain upgrade is performed. Note, when enabled, gRPC will also be automatically enabled.
