@magnars t starts at 1000 and tx starts from 13194139534312, 10 billion datoms is Datomic's reccomended limit

@danielstockton @magnars In fact the 10B recommendation doesn’t stem from tx or t numbers, but rather from logistical size considerations for DBs that large (i.e. restore from backup of that size can take hours or days depending on infrastructure)

i know, i just interpreted magnars question as "when as-of takes a number, how does datomic know whether it represents a T or a tx" and i presumed the id ranges are far enough apart for them never to overlap

ah.

@marshall, and also the amount of ram that holding all the roots and idents and whatnot would use, right?

yep
