max data file size

[trendl]

Hi,

is there an upper limit on the data file size? Does using multiple
databases hence multiple files provide performance gain?

Thanks,
Tomas

RavenDB's underlying data store is ESENT. The same database microsoft builds Exchange on top of. It supports volumes into the terrabytes.

[Mauro Servienti]

if I recall well 16tb

According to Wikipedia, an ESENT database can hold up to 16 terabytes, see  http://en.wikipedia.org/wiki/Extensible_Storage_Engine#Databases

But I think you might hit a limit with the Lucene indexes if you try and index that much data!

Esent can hold up to 16tb, and as Matt indicated it may not be the bottleneck at those sizes

You probably want to consider sharding if you ever get to that scale. Multi-tenancy should be used by different applications, or the same application in different contexts

[Oren Eini (Ayende Rahien)]

The physical limit is 16 TB for documents.

Indexes are stored separately, and are not counted for this measure.

You can have multiple databases, and each will have a 16 TB size limit.

Note that at those sizes, we recommend sharding the data.
