Using SciDB as a key/value store



May i use SciDB as a key/value store ?
Is there a built-in type for binary large object(ie blob) in SciDB ?



Hi Xavier

There’s currently no builtin blob datatype.
There is a string datatype that has a variable size.
User-defined types can be introduced fairly easily (see source for example).

Every value in a SciDB array has a uint32 size. So values may not exceed ~4GB. More restrictive limits may apply at other places in the architecture.

Does this help answer your question?


Yes it does.
Thanks for your help.
