Release 1.7.0 ¶

Updates with special concerns¶

MultipleValues standing queries will not migrate from Quine 1.6.4.

If you have any MultipleValues standing queries and you are using RocksDB, your database files will not carry forward.

If you are using MultipleValues standing queries and Cassandra, perform the following steps to remove all MultipleValues data while leaving your graph intact:

Before shutting down Quine 1.6.4, use the API to delete all MultipleValues standing queries
After shutting down Quine 1.6.4, but before launching Quine 1.7.0, use cqlsh to TRUNCATE standing_query_states
After launching Quine 1.7.0, use the API to recreate all MultipleValues standing queries

Ad-hoc queries now reflect SETs and REMOVEs made during the query

If your ad-hoc (i.e., ingest, Cypher standing query output, or /query/cypher/ POSTed) queries rely on the original "capture state on MATCH" behavior, add a variable with WITH capturing the state you need.

For example, MATCH (n) SET n.x = 2 RETURN n.x AS oldX becomes MATCH (n) WITH n, n.x AS oldX SET n.x = 2 RETURN oldX

Enhancements¶

MultipleValues standing queries have been rewritten from the ground up for massive performance gains
Failing to deserialize an ingested record now logs a warning + INFO message, and resumes the stream, rather than moving the stream to an error state
Updated the behavior of the SET and REMOVE clause to reflect their expected changes on the in-memory copies of query-related values
Protobuf message types can now be set by short name or full name
Added toProtobuf Cypher serialization procedure
Protobuf procedures now yield null values on failing to serialize/deserialize
Enhanced telemetry with basic feature usage indicators to support prioritizing most-used features
Simplified and tuned ingest registration logic

Unregistered routes will now return a "not found" page instead of an error about a missing query parameter
The cypher interpreter will no longer report "undefined variable" when returning variables bound to pattern expressions (e.g., MATCH p=(a) RETURN p)

Release 1.2.0 ¶

This release brings several API improvements, new Cypher query features, and persistence backend bugfixes and optimizations to better support supernodes and other extreme-scale datasets. Some of these changes affect the data format on disk, and accordingly data from prior versions (<= 1.1.2) can not be used with Quine 1.2.0 without migration. Furthermore, this release increases the minimum supported Java version to 11.

Features¶

Add reify.time, a Cypher procedure to generate a uniform structured representation of timestamp data within the graph, to make time-related data analysis via Standing Queries easier and more consistent
Add a REST API endpoint to request a specific node save a snapshot and go to sleep
Added support for Cypher subqueries via the CALL {} syntax
EXPLAINed query ASTs will now be logged at debug level, if enabled
Improved serialization for nodes with an extremely large edge and/or property counts in the persistence backend
Nodes with an extremely large edge and/or property count can now be correctly accessed via the Literal Operations REST APIs
Iteration and sort order of Map-type values in Cypher queries are handled consistently
Add a configuration option for writing updates to disk before applying effects in-memory: quine.persistence.effect-order
Add a startup check to verify that Cassandra's configuration matches the provided Quine configuration, warning if there is a mismatch
Calling the debug API on a node in a historical query now only includes journal events up to the time of the historical query

Bugfixes¶

Application start up can no longer log an opaque warning like "Current state = CODING, previous state = FLUSHED"
Setting snapshot-singleton=true, snapshot-schedule=on-node-update, and journal-enabled=false no longer causes the most recent event on a node to be dropped
Map-type values in Cypher hash to a consistent value, independent of how they were constructed
Accessing nodes just as they fall out of the cache can no longer cause the system to enter a failsafe mode
Historical queries that restore journals with noncommutative effects after a snapshot from Cassandra apply updates in order
Fix an issue with RocksDB where some Standing Query states weren’t restored
Added a minimum header width to recipe status query output
Fix an issue where standing queries were not properly restored on startup

Misc¶

Remove support for DistinctId queries that do not specify a DISTINCT keyword
Remove support for toInt in Cypher queries (use toInteger instead)
Remove support for filter and extract in Cypher queries (use list comprehensions instead)
ID values returned via the exploration UI are now pretty-printed
Use Cypher for query UI edge queries for better performance and fewer timeouts when querying supernodes
Make recipes and example queries more consistent in styling
Make use of datetime() in Apache log recipe to parse timestamps
When the system clock moves backwards, Quine handles the issue transparently. Change the log level for this occasion from warn to info.

Increase resilience of persistence operations in deployments with unreliable persistors
Improve performance of historical queries involving nodes with many edges
Add persistor exceptions, including timeouts, to the list of exception types that are retried for ingest queries and when shouldRetry = true
