Change Log

2.2.4 - 2022-02-22

Added

The :db/ident and :id attributes may now use compound keys.

Fixed

Fixed a problem where resolving a pattern on disk will lead to an error if the resolution is empty.

2.2.3 - 2021-11-10

Added

The asami.core/entity function now accepts Connections as well as Databases. This will select the latest database from the connection.

Changed

The third argument to the asami.storage.Database/entity function is now required. This change should not affect most users, as this is an internal function and should be accessed with asami.core/entity, which has not changed.

Fixed

Using an entity :id will now correctly select and update entities in transactions.

2.2.2 - 2021-10-19

Added

Added a new :input-limit option to transact. When included, the transaction will attempt to keep at or below this number of triples.

2.2.1 - 2021-10-16

Fixed

Accepting java.time.Instant objects on the since and as-of database functions.

2.2.0 - 2021-10-10

Added

transact-async has been added. On the JVM this will return a future that has not yet been completed. There is currently no difference between transact and transact-async for ClojureScript.

Changed

Transaction results now includes datoms that reflect the changes to the database, and not the changes requested of the database.
Calling delete-database on an in-memory database URL will clear any open connections of data. If data is transacted into the connection, it will be reattached to the database registry as if it had been freshly opened.

2.1.3 - 2021-09-10

Added

OR expressions no longer require the same variable bindings for each sub-expression

2.1.2 - 2021-08-18

Added

Queries now test that projected variables in the :find clause appear in the :where clause.
In memory graphs now how transaction IDs (not yet exposed in public APIs).

Fixed

User plans now using the correct return type, so complex queries don't cause errors while testing.
Multiple bindings in the :in clause will now combine correctly during testing.

2.1.1 - 2021-06-28

Added

Added asami.core/export-str. This is a shortcut to convert a data export to a string, suitable for clojure.core/spit, since the default will write this as a LazySeq label.
asami.core/import-data now accepts an opts argument, the same way that edn readers do. This is used when reading from edn text.

Changed

Single-end bindings on transitive constraints applied to memory graphs are now using the unbound form internally to gain log(n) complexity.
Cleanups to internal code.

Fixed

In memory transitive attribute constraints have been fixed for the case of an unbound constraint for a given attribute.
Boolean values saved to disk no longer create errors when reading back false.

2.1.0 - 2021-06-22

Added

Transactions include resource usage, so resources (files) can be cleaned up after failure.

Fixed

Recursive entities now correctly cut the recursion when extracting entities from the graph.
Shutdown now releases connections. This truncates files to used space only.

Changed

Nodes now serialized using vector notation and without a redundant space. Previous node deserialization still supported.
Serializing numbers is now smaller.
Arrays and maps can now be serialized as values. This will show up in the API soon.
Indexes now share file resources. This has removed 4 files.

2.0.6 - 2021-06-10

Added

A new CLI for loading data and executing queries. This builds natively with GraalVM.
Exposing now and instant? from asami.core
Serialization of arrays and maps. This will enable upcoming features.
An :id attribute can now be used as a synonym for :db/ident. These values are not removed from entities, unlike the :db attributes.

Fixed

Aggregates correctly group even when selections are not sensible.

Changed

Integrating entity code fully into Asami. This is no longer imported from Zuko.
Minor efficiency improvements to in-memory updates and reads.
Booleans are now encoded into IDs and no longer serialized.

2.0.5 - 2021-05-27

Changed

Entity conversion to statements is no longer recursive on arrays. This allows for larger arrays.

2.0.4 - 2021-05-07

Fixed

Fixed missing functions on read-only trees

2.0.3 - 2021-05-06

Fixed

Fixed problem where the internal node IDs were not initializing from saved transactions.
Imports now update the node ID generator to allocate IDs after imported data.

2.0.2 - 2021-04-28

Fixed

Removed multiple extensions for filenames.
Fixed grouping for some aggregate queries.

2.0.1 - 2021-04-20

Fixed

Entity references to top-level entities no longer delete the referenced entity when the reference changes.

Added

Expanded handling of graph conversion for query objects, including getting the latest database from a connection.

Changed

Updated to Zuko 0.6.4.
Top level entities now include :tg/owns edges to all sub structures that they own.

2.0.0 - 2021-04-08

Changed

Changed

Updated to Zuko 0.6.0. This introduces new portable i/o operations.

2.0.0-alpha7 - 2021-03-20

Changed

Updated to Zuko 0.5.1. This allows arbitrary keytypes for entities.

2.0.0-alpha6 - 2021-03-19

Changed

Updated to Zuko 0.5.0. This means that entities without a temporary ID do not map their new IDs back to themselves in the :tempids of transactions.
Zuko no longer brings in the unneeded Cheshire and JacksonXML dependencies.
Cleaned up reflection in the durable layer, with a 35% speed improvement.

2.0.0-alpha5 - 2021-03-18

Added

count-triple implemented to scan index tree with reduced block access.

2.0.0-alpha4 - 2021-03-17

Added

Supporting lookup refs in transactions (thanks to @mk)
Supporting transitive attributes for durable graphs.

Fixed

Fixed some transitive attribute operations that did not handle zero-steps correctly.

Changed

Fixed

Fixed bug that ignored :db/retract statements.

2.0.0-alpha2 - 2021-03-09

Added

Internal node type. This avoids the need for interning keywords as nodes.
Added the asami.Peer class. This is very early access.

Changed

Updated to Zuko 0.4.4. This shifts the function whitelist into Zuko, and reduces the number of functions referenced in ClojureScript.
Added functions for and and or.

Fixed

Functions from clojure.string can now be accessed in Clojure.

Fixed use of macro as a value in CLJS

Added

delete-database function.

Fixed

Fixed problem that duplicated optional constraints during query planning.
Fixed zero steps for transitive paths between nodes.

optional operator, as per the SPARQL OPTIONAL operation.
Added show-plan function to observe how a query will be performed.

Changed

Selecting variables as transitive attributes returns a path vector for that column.

Fixed

Fixed issue with filter arguments sometimes failing.
Transitive querying. Now handles unbound path elements better, planning is improved, and zero-steps are properly handled.
Tuple selector in the :find clause now work for single elements, and with empty results.
Single graph element in the :in clause now works.

1.1.0 - 2020-08-05

Added

Introduce new :find clause syntaxes (see Find Clause Description doc for details)
Created documentation for the API, data structures, querying, and creating transactions.

Changed

Entities now represent multi-arity attributes as a set of values. If more than one of an attribute is found, then a set of those values is returned in the entity. Similarly, providing a set will result in using the attribute multiple times in the graph.

Fixed

Entity arrays are now returned as vectors and not lists.

Added

New Datomic-style API
Implemented Datom object for transaction reporting
