nosql - Clarifying questions about MongoDB -

these newb questions, i'm sure, let's out of way sooner rather later: i'm new mongodb.

does mongodb guarantee entry saved? e.g. if have process load 1,000,000 objects mongodb, guaranteed load or @ to the lowest degree retry / raise error when error occurs?

is numberlong integers? if wanted utilize high precision decimals?

i know v8 / spidermonkey can fast c, has done benchmarks calculations of info in mongodb? example, if wanted find average on 1,000,000 items loaded in 1, in map-reduce way programming language... have people run in problem using javascript mongodb? think?

most mongo drivers allow insert info "safe-mode" waits insert finish sucessfully, or raises error on failure. done behind scenes calling getlasterror command after insert. mongodb's underlying storage format bson doesn't back upwards high-percision decimals, 64-bit floating point numbers. javascript in mongodb single-threaded, , can bit slow. javascript engine upgraded v8 should speed things up.
