Solandra 与 ElasticSearch
我们正在使用 Cassandra 数据库,该数据库将存储 PB 级的数据。我们正在考虑使用 ElasticSearch 或 Solandra,但在决定使用哪一个之间我们很开心。我想知道我们的数据库是否可能变得太大。我知道 ElasticSearch 是可扩展的,但可扩展到什么程度 - 特别是对于 Cassandra 数据库。
另一方面,Solandra 是为 Cassandra 设计的,具有高度可扩展性,但同样,可扩展性到什么程度呢?
两者都是可扩展的,但使用 Cassandra 的可扩展性如何?
We are working with a Cassandra database that will store data in the petabyte range. We are thinking of using either ElasticSearch or Solandra, but we are having a fun time deciding between which to use. I'm wondering if the our database might get too large. I know ElasticSearch is scalable, but to what extent - especially with a Cassandra database.
Solandra on the other hand is made for Cassandra and is highly scalable, but again, to what extent?
Both are scalable, but how scalable using Cassandra?

Solandra 的使用范围为数十 TB。
你是说你想在 solandra 或一个子集中索引 PB 数据吗?我认为如果你想要 1 个包含 PB 数据的大索引,那么你就超出了极限。但如果你想要 PB 级的索引,那么这将与 Cassandra 的规模相同。
您计划运行多少个节点?每个节点有多少磁盘?
Solandra is being used in the 10s of Terabytes range.
Are you saying you want to index a PB of data in solandra or a subset? I think if you want 1 big index with a PB of data you are stretching the limits. but If you want a PB of indexes, then this will scale the same as Cassandra.
How many nodes are you planning to run? how much disk per node?
