Release Notes-TigerGraph 2.3
Release Date: April 1, 2019

New Features
Kafka Loader
- Load real-time streaming data using industry standard Apache Kafka
- Easy to configure: CREATE, GRANT... ready to use!
- Fault-tolerant and distributed
Analytics and Solutions - Graph Algorithm Library
- ​More universal: vertex type & edge type can be specified at runtime.✅
- ​Similarity: New algorithms: Cosine and Jaccard✅
- ​Path: More variations of Shortest Path✅
- ​Community: More accurate implementation of Louvain modularity✅
GSQL Enhancements
- ✅ Schema: Vertex Attribute as PRIMARY_KEY
- In classic GSQL, vertex Primary_ID is special, not consider an attribute. This minimizes storage space.
- New option to treat the Primary_ID as a regular attribute.
- ✅ MultiGraph: Different graphs can use the same query names and job names.
- ✅ Loading: User can choose how to handle edges with missing source or target vertex.
- Default: If either the source id or target id of a new edge refers to a nonexistent text, then the system will create the necessary vertices with default values.
- New option: If the source or target vertex doesn't exist, don't create the edge.
- ✅ Catalog Display: Enhanced SHOW command
- Show vertices, edges, jobs, or queries.
- Accepts a regEx or glob pattern argument to show only selected items
GraphStudio Enhancements
- ​User-defined tuples as attributes are supported (already supported in GSQL).✅
- ​When displaying a directed edge, only show the forward edge and not its companion reverse edge.✅
- ​Text size of vertex and edge label is adjustable.✅
- ​After a query is compiled, show its REST endpoint.✅
- ​See graph schema while writing GSQL queries.✅
- ​Better editing and installing experience for queries with dependencies.✅
Other Spec Changes
- ​Single Sign On: The security.sso.saml.sp.hostname parameter is replaced by security.sso.saml.sp.url, which must be a full URL, not just a local path.âš
- ​If a query is issued while another query is being installed, the query will wait rather than exit.✅
- ​CHANGE: PRIMARY_ID as INT or UINT is no longer deprecated. To support more general use of attributes as PRIMARY_ID, the following data types may be used: STRING, INT, UINT✅
- ​The keyword COMMENT is no longer reserved.ℹ
- ​The built-in REST endpoint POST /ddl (Online Post) is deprecated. Its functionality is already covered by the improved and unified LOADING JOB introduced in v2.0âš
