Change Log

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

• Updated to Zuko 0.6.2, core.cache 1.0.207, and ClojureScript 1.10.844.

2.0.0-alpha9 - 2021-04-02

Added

• Locking the transaction file during writes to prevent multiple processes from trying to modify it concurrently.

Changed

• Opening files no longer allows variations on paths using . and ..

2.0.0-alpha8 - 2021-03-30

Fixed

• Addressed concurrency bugs found in the JVM, for both memory-based and durable storage.

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

• Updated to Zuko 0.4.6. This adds lookup refs to entities in transactions.

2.0.0-alpha3 - 2021-03-10

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

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

1.2.0 - 2020-08-19

Added

• 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.

• 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
