XAUTOCLAIMScan and claim idle pending entries starting from a cursor.
| 语法 | XAUTOCLAIM key group consumer min-idle-time start [COUNT count] [JUSTID] |
| 分组 | stream |
| 参数个数 | -6 |
| 起始版本 | 1.0.0 |
| 标志 | write |
| 复杂度 | O(log P + K + COUNT log N); the idle filter runs before the take, so a PEL of fresh entries is walked in full |
| Redis 兼容性 | differs: the next-cursor is last-claimed+1 rather than 0-0 when the PEL scan completes, so a client looping until 0-0 needs one extra round trip |
