Numbers I get on my 3.2 GHz i7-8700B (median time per test, ms):

version add-1 add-5 add-all init retract-5 q1 q2 q3 q4 qpred1 qpred2
0.17.1-jvm 795.8 670.7 651.8 79.4 617.5 2.3 5.4 8.2 13.1 7.1 27.3

Tests are as follows:

Test Description
add-1 Add 100k datoms to an empty DB, one datom per transaction
add-5 Add 20k entities to an empty DB, 5 datoms per transaction, 100k datoms total
add-all Add 20k entities to an empty DB in a single transaction, 100k datoms total
init “Fast” datascript DB creation from an already sorted array of datoms (used in DB deserialization), 100k datoms
retract-5 Retract 20k entities from a DB with 100k datoms. Each entity removes 5 datoms. 1 entity per tx.
q1 Query with 1 clause over a DB with 100k datoms, ~12k tuples in resultset [:find ?e :where [?e :name "Ivan"]]
q2 Query with 2 clauses, 1 join, ~12k tuples [:find ?e ?a :where [?e :name "Ivan"] [?e :age ?a]]
q3 Query with 3 clauses, 2 joins, ~6k tuples [:find ?e ?a :where [?e :name "Ivan"] [?e :age ?a] [?e :sex :male]]
q4 Query with 4 clauses, 3 joins, ~6k tuples [:find ?e ?l ?a :where [?e :name "Ivan"] [?e :last-name ?l] [?e :age ?a] [?e :sex :male]]
qpred1 Query with a predicate, ~50k tuples [:find ?e ?s :where [?e :salary ?s] [(> ?s 50000)]]
qpred2 Query with a predicate and dynamic input, ~50k tuples [:find ?e ?s :in $ ?min_s :where [?e :salary ?s] [(> ?s ?min_s)]]

For Datomic an datomic:mem:// database was used.

What we see:

  • 20..40% faster transactions,
  • 75% faster deserialization (db-init),
  • No significant change on queries,
  • JVM transactions are more than twice as fast as V8,
  • JVM queries are 3-4 times as fast as V8,
  • DataScript transactions are 25..70% faster that Datomic in-memory. Query times vary.

0.17.1

  • Upsert works in vector form too (issue #99, #109)

  • Guard conn? will check that value is derefable instead of checking for (instance? Atom)

0.13.0

  • [ BREAKING ] Old datascript.core (internal namespace) was renamed to datascript.db
  • [ BREAKING ] datascript.shim (internal namespace) was renamed to datascript.arrays

Motivations:

  • Usage of top-level namespaces is discouraged and even generates a warning in CLJS.
  • Better sooner than later.
  • 0.13 seems like a great number for this sort of release.

Migration procedure:

  • Just change (require '[datascript :as d]) to (require '[datascript.core :as d]) and you’re good to go.

For the sake of easy migration, there’re no other changes in this release. Just renamings.

0.12.2

  • Fix null pointer exception when contains? is called with an entity (PR #114, thx Kevin Lynagh)

0.12.1

  • db-init respects :db/index property

0.12.0

[ BREAKING ] Introducing new :db/index schema attribute:

  • Attributes are not put to AVET by default anymore

  • Following attributes are put to AVET:

    • :db/index true
    • :db/unique :db.unique/identity
    • :db/unique :db.unique/value
    • :db/valueType :db.type/ref

  • All attributes put to AVET should be comparable. Note: maps and list are not comparable by default, vectors are compared value-by-value

  • [ BREAKING ] Min/max aggregation functions will only work on a comaparable values

Benefits:

  • You can finally store any trash easily and reliably in DataScript database: maps, vectors, functions, JS objects. It doesn’t even have to be comparable. Just do not mark it as :db/index and do not make it :db.cardinality/many
  • Faster transactions. There’s ⅓ less indexes to fill
  • Good defaults. Most cases where you’ll probably use AVET (lookup by value)—lookup refs, external ids, references—they are all indexed by default

Caveats:

  • Your code may break (see below)
  • Queries can do lookup by value event without :db/index attribute, but it’ll be slower

Migration procedure:

  • Check your code for datoms, seek-datoms calls with :avet index, and index-range call
  • Check your queries to see if they utilize AVET index. It happens when you use this pattern: [?free-var <constant-attr> <constant-value>]
  • Mark necessary attributes with :db/index true in the schema

0.11.6

  • Ported BTSet to JVM

0.3.0

Proper entities implementation:

  • Entities are now lazy and implement usual Map protocols
  • [ BREAKING ] When accessing attribute of :db/valueType :db.type/ref, its value will be automatically expanded to entites, allowing for recursive exploration of entities graphs (e.g. (-> (d/entity db 42) :parent :parent :children))
