[1.5.1] - 2023-12-12

Release of pyTigerGraph version 1.5.1.

Added:

• Support to use the connection's username and password in getToken()

Fixed:

• Errors when upserting MAP attributes

v1.5

[1.5] - 2023-09-25

Release of pyTigerGraph version 1.5.

Added:

• Object-oriented schema definition and modifcation. Define graph schemas in native Python, without knowing GSQL.
• gsql() handles some common error cases and raises an exception if they occur.

Changed:

• Dataloaders that experience a parsing error due to missing/dirty data handle the error more gracefully.
• Removed the use of pyTigerDriver for GSQL operations.
• Various bug fixes.

v1.4.2

[1.4.2] - 2023-09-01

Release of pyTigerGraph version 1.4.2.

Fixed:

• Fixed behavior of not being able to use upsertVertexDataframe() when MAP types were in a column.

v1.4.1

[1.4.1] - 2023-06-05

Release of pyTigerGraph version 1.4.1.

Fixed:

• Consistent batch sizes in the EdgeLoader and EdgeNeighborLoader
• Handle empty MAP attributes in dataloaders correctly
• Type error in customizeHeader() when passing integer parameters
• Built-in trainer eval metrics collection

v1.4.0

[1.4] - 2023-05-16

Release of pyTigerGraph version 1.4.

Note: if you are using the Graph Data Science dataloaders, continue to use the latest 1.3.x version until you have upgraded your ML Workbench installation.
There is a incompatibility between v1.3 and v1.4 of pyTigerGraph and the corresponding ML Workbench versions.

Added:

• Additional Query Management Support
  • showQuery() returns the GSQL of a given query.
  • getQueryMetadata() returns the metadata details about a query, such as input parameters and what is returned in PRINT statements.
  • getRunningQueries() shows the statistics of queries currently running on the graph.
  • abortQuery() aborts a selected query by ID or all queries on the graph.
• Additional System Management Support
  • ping() is a public API to check the health of the TigerGraph server.
  • getSystemMetrics() monitors system metrics such as CPU and RAM usage.
  • getQueryPerformance() returns real-time query performance statistics over a given period.
  • getServiceStatus() returns the status of TigerGraph services specified in the request.
  • rebuildGraph() rebuilds the graph immediately.
• Built in Graph ML models and Trainer
  • Various GraphSAGE models for vertex classification and regression, as well as link prediction
  • NodePiece MLP model for vertex classification.
  • General purpose trainer to enable training of Graph ML models in a concise fashion.
• Transforms
  • PyGTemporalTransform to create a sequence of subgraphs for a given batch of data, in a temporal manner.
  • NodePieceMLPTransform to transform a batch produced by a NodePiece dataloader into a batch that can be fed into a PyTorch multilayer perceptron.
• Additional Dataloader Support
  • SSL Support: two-way SSL encryption via Kerberos
  • Collaborative dataloaders: use dataloaders on multiple machines to pull batches from the same Kafka queue. Helpful for data distributed model training.
  • Datetime support in dataloaders: Output DATETIME attributes from the database using the dataloaders. Exports as UNIX epoch timestamps.
  • Optional distributed_query parameter in dataloaders if running on distributed database clusters. If set to True, installs the dataloader using the DISTRIBUTED keyword in the query heading. Useful for distributed database clusters.
  • stop() function in dataloaders: Kill the query producing batches for the dataloader immediately. Helpful for stopping the production of batches sent to Kafka after breaking out of a training loop.

Changed:

• Dataloader factory produces multiple dataloaders if filter_by is a list of different filters.
• Improved the scalability of the NodePiece dataloader.

v1.3.4

[1.3.4] - 2023-04-13

Release of pyTigerGraph version 1.3.4.

Fixed:

• The fetch() function of various dataloaders was previously ignoring a custom delimiter, now resolved.
• Improved scalability of NodePiece.

v1.3.3

[1.3.3] - 2023-04-03

Release of pyTigerGraph version 1.3.3.

Fixed:

• Made the output of batched dataloaders a consistent batch size, rather than using approximate methods.
• Change getVertexCount() endpoint to more scalable solution.

Added:

• customizeHeader() function to change default timeout and response size values.

v1.3.2

[1.3.2] - 2023-03-13

Release of pyTigerGraph version 1.3.2.

Fixed:

• Logic of shuffling vertices in dataloaders when filter_by attribute was used
• SSL certificate handling when custom certificate is used
• Remove ANSI escape characters from output of .gsql() calls

v1.3.1

[1.3.1] - 2023-02-16

Release of pyTigerGraph version 1.3.1.

Fixed:

• Support for multi-edges in the upsertEdges() function
• Changed the default delimiter used in the dataloaders from , to | in order to support MAP attributes with no user change.
