DEBUGDebug subcommands; SLEEP blocks the shard, other subcommands are tolerated as OK.
| 语法 | DEBUG SLEEP seconds | subcommand [args ...] |
| 分组 | server |
| 参数个数 | -2 |
| 起始版本 | 1.0.0 |
| 标志 | readonly, admin |
| 复杂度 | SLEEP: parks the ANSWERING shard's reactor thread for the duration (other shards keep serving). Everything else: O(1) |
| Redis 兼容性 | differs: SLEEP is the only subcommand with an effect and it blocks one shard, not the server; every other subcommand is accepted and answered OK without doing anything |
