Description
在二哥的Java进阶之路的八股面经里 Redis 主从复制（问题 17）
原文中提到“Redis 2.8 之后主节点为每个从节点维护一个复制积压缓冲区”，
按其他的资料和我的理解这里应该是 复制缓冲区 而非 复制积压缓冲区，
复制积压缓冲区（repl_backlog_buffer）是主节点上的全局环形缓冲区，主要用于从节点断线重连后的 PSYNC 增量复制；而主节点为每个从节点单独维护的，应该是 replication buffer（复制缓冲区），用于在线状态下的命令传播。

Research direction
Find the Redis 主从复制 section in the Java interview notes, specifically question 17, and compare the two replication buffer terms described in the issue. Update the wording so the per-replica buffer and the global replication backlog buffer are distinguished, then review the surrounding text for consistency.
