Find the bootstrap transactions for a datomic database. Bootstrap transactions are the first few transactions which create all the datoms necessary for datomic to work (e.g., the initial partitions, types, attributes, and tx functions). They are not accessible directly via the transaction log.

bootstrap-txes-0-9-5173.edn

;; Result of bootstrap-txes function above under datomic 0.9.5173
;; Bootstrap transactions are 0, 
;; More bootstrap transactions or datoms may be added in later datomic versions.
;; First non-bootstrap transaction is always T >= 1000.
;; Format is [[t [[e a v tx added] ...] ...] ...]
