uwdata/mosaic v0.11.0

on GitHub

Changelog:

• Breaking: Replace apache-arrow with @uwdata/flechette to access Apache Arrow IPC data with better performance and smaller footprint. While the API for Flechette tables mirrors many aspects of the Arrow JS reference implementation, it is not a perfect one-to-one replacement. It is possible that some Mosaic users may need to adjust query result processing in response.
• Breaking: Redesign the data cube indexer to write index tables into a named schema (default 'mosaic'). This allows data cube index tables to be managed in a largely isolated environment and to be reused across users and sessions. Temporary index tables are no longer supported, as temporary tables can not be created within a named schema.
• Breaking: Remove temp option for data cube index tables.
• Breaking: Remove data cube indexer enabled method, instead use get/set properties.
• Add data cube indexer schema get/set properties.
• Add data cube indexer dropIndexTables() method. This method issues a query to remove the entire data cube index table schema. It should be called if base tables are updated, causing index tables to become stale and inaccurate.
• Add Selection include to define a Selection that includes the clauses from one or more upstream selections. This addition allows selections to be composed to build up larger clause sets from sub-selections.
• Add client initialize method. This method supports dynamic client re-initialization, issuing new field info and client query requests.
• Fix throttle utility to be resilient to callback rejections. (thanks @andyrooger!)
• Fix canceled queries by rejecting them, rather than leaving them pending. (thanks @andyrooger!)
• Fix index creation queries to no longer be canceled when clearing the data cube indexes. These indexes may already be used in other queued requests. (thanks @andyrooger!)
• Fix Plot class to re-initialize mark clients upon dynamic field updates.
• Fix data cube indexer to generate correct averages in variance and covariance calculations. (#487)
• Fix broken usage of json_format and add loadJSON test. (thanks @geoffreyd!)
• Fix management of cancelled queries, remove race condition. (thanks @andyrooger!)
• Fix query consolidation to flag aggregate queries with no groupby. (#479, thanks @andyrooger!)
• Fix variable access typo in DuckDBStatement within node.js DuckDB lib.
• Fix time interval year span calculation. (#484)
• Fix nearest interactor with param-compatible clause for single-field selections. (#502)
• Fix nearest interactor for consistent param and selection updates. (#508)
• Fix Coordinator queryRequest to always return a Promise. (#507)
• Update Jupyter widget, remove temp_indexes property and add dataCubeSchema property.
• Update types, method signatures in Coordinator and DataCubeIndexer.
• Update test runner from mocha to vitest. (thanks @domoritz!)
• Update Coordinator API documentation.
• Update athletes example to use Selection include. We now use an upstream selection to limit text search options to the current sport and sex.
