Function sentinelInstanceMapCommand

src/sentinel.cpp:1742–1748

This function is used in order to send commands to Redis instances: the * commands we send from Sentinel may be renamed, a common case is a master * with CONFIG and SLAVEOF commands renamed for security concerns. In that * case we check the ri->renamed_command table (or if the instance is a slave, * we check the one of the master), and map the command that we should send * to the set of renam

 * to the set of renamed commands. However, if the command was not renamed,
 * we just return "command" itself. */
