Database 如何在不同的存储介质上存储不同的Cassandra表？
在阅读中，似乎可以将表配置为转到某个存储介质。在尝试搜索文档之后，我找不到任何关于它的信息 Cassandra的存储配置应该如何支持这种设置Database 如何在不同的存储介质上存储不同的Cassandra表？,database,cassandra,storage,media,Database,Cassandra,Storage,Media,在阅读中，似乎可以将表配置为转到某个存储介质。在尝试搜索文档之后，我找不到任何关于它的信息 Cassandra的存储配置应该如何支持这种设置 非常感谢 Cassandra 1.1 and later releases provide fine-grained control of table storage on disk, writing tables to disk using separate table directories within each keyspace director
非常感谢
Cassandra 1.1 and later releases provide fine-grained control of table storage on disk, writing tables to disk
using separate table directories within each keyspace directory. Data files are stored using this directory
and file naming format:
/var/lib/cassandra/data/ks1/cf1/ks1-cf1-hc-1-Data.db
The new file name format includes the keyspace name to distinguish which keyspace and table the file
contains when streaming or bulk loading data. Cassandra creates a subdirectory for each table, which
allows you to symlink a table to a chosen physical drive or data volume. This provides the capability to
move very active tables to faster media, such as SSD’s for better performance, and also divvy up tables
across all attached storage devices for better I/O balance at the storage layer.
