Neo4j Aura Database feature update

The following core Neo4j Database features are now available for users in Aura:

Surface for Developers and Data Scientists

Greatly improved scalability of the block format importer, allowing for good performance even for large data sets.
Metric <prefix>.store.size.database.available_reserved becomes public. This allows us to estimate reserved but available space in the database, in bytes. Documentation is available here.

Language and Graph Model

Introduces support for CALL {...} IN CONCURRENT TRANSACTIONS. This optimizes the use of available processing resources, enabling subqueries to be broken up into multiple batches and executed concurrently. Documentation is available here. Syntax:

CALL {
       subQuery
} IN [[concurrency] CONCURRENT] TRANSACTIONS
[OF batchSize ROW[S]]
[REPORT STATUS AS statusVar]
[ON ERROR {CONTINUE | BREAK | FAIL}];

SHORTEST
: This release introduces CYPHER statements:
ALL SHORTEST, SHORTEST k, SHORTEST k GROUPS, ANY
. The new statements also support Quantified Path Patterns, combining shortest path-finding with the expressiveness of QPPs. Documentation is available here.
A new SubtractionNodeByLabelsScan operator delivers improved matching performance for label expressions with negation such as:

MATCH (:A1&A2&!B1&!B2)....

Documentation is available here.

For
GQL conformance
we have introduced
upper() and lower() functions, which are aliases for the toUpper() and toLower() functions
.Documentation is available here and here.
A new *
deprecatedBy column has been added to the output of SHOW PROCEDURES [YIELD
] and SHOW FUNCTIONS [YIELD
]
* to show if the deprecated procedure/function has a replacement. Documentation is available here
Metric <prefix>.store.size.database.available_reserved becomes public
. This allows us to estimate reserved but available space in the database, in bytes. Documentation is available here.
FOREACH will now interpret scalar values as a list
, similar to UNWIND.

Please refer to the Neo4j changelog for full details of the changes.
