作者:俊达说明在clickhouse中,如果我们想实现数据多副本存储,以提高数据可用率和查询性能,可以使用复制表。支持数据复制的表引擎包括:ReplicatedMergeTr...
每一个 part 内的.bin文件存储了 n 个 granules,用.mrk文件记录每一个 granules 在.bin文件的地址偏移[ ClickHouse 会在后台不断合并同一个 partition 的不同 parts,直到大小/分布达到“预期” 主键的选择应该尽可能考虑周全,因为主键是无法修改的,只能建新表后数据迁移。
source_replica (String) — 源副本的名称。 new_part_name (String) — 新部件的名称。 parts_to_merge (Array (String)) — 要合并或更新的分区的名称。 is_detach (UInt8) — 该标志指示 DETACH_PARTS 任务是否在队列中。 is_currently_executing (UInt8) — 该标志指示当前是否正在执行特定任务。 num...
