Changelog

All notable changes to FlowKit will be documented in this file.

The format is based on Keep a Changelog.

Unreleased

Added

Changed

  • Mode is now available for use with categorical metrics when running joined spatial aggregates via api. #2021
  • Flowmachine now includes the version number in query ids which means cache entries are per-version. #4489

Fixed

  • Fixed dangling async tasks not being properly cancelled during server shutdown #6833

Removed

1.30.0

Changed

  • FlowMachine now requires python >= 3.11

Fixed

  • Direction enum not being recognised #6787

Removed

  • Removed Oracle fdw

1.29.0

Added

  • New flowmachine query CalendarActivity, which retrives subscribers pattern of active days
  • New flowmachine queries PerValueAggregate and RedactedPerValueAggregate, which group by the value column of another query and apply an aggregate to subscribers with that grouping.
  • New flowapi queries and flowclient functions for calendar_activity and localised_calendar_activity, which return counts of subscribers per sequence of active days, and per sequence of active days additionally grouped by the subscribers reference location
  • Added new StringStatistic enum, which enumerates valid statistics for use with postgres string types

Changed

  • HistogramAggregation has moved to flowmachine.features.nonspatial_aggregates
  • Statistic moved to flowmachine.core.statistic_types
  • TotalActivePeriodsSubscriber no longer returns an extra inactive_periods column

1.28.1

Fixed

  • Fixed 500 error when getting api spec from FlowAPI #6686

1.28.0

Added

  • Added support for Parquet foreign tables using parquet_fdw

Changed

  • FlowKit test and synthetic data now uses parquet foreign tables.

Warning

The location of the parquet files in the container is /parquet_data, if you are testing with larger amounts of data you may wish to add an additional bind mount for this location.

Warning

This change is not backwards compatible with earlier releases of FlowDB, and you will need to repopulate your deployment. We recommend combining this change with the new parquet support.

  • FlowETL is now built on Airflow 2.9.2

1.27.0

Added

  • Added FlowDB table infrastructure.invalid_cell_info for recording cell information that could not be included in infrastructure.cell_info (including cells with null or duplicate cell IDs). #6626
  • The file name of FlowDB's automatically generated at init config file can now be specified by setting the AUTO_CONFIG_FILE_NAME environment variable. By default this is postgresql.configurator.conf.

Changed

  • FlowDB now triggers an ANALYZE on newly created cache tables to generate statistics rather than waiting for autovacuum
  • FlowDB now produces JSON formatted logs by default. Set FLOWDB_LOG_DEST=csvlog for the old default behaviour.
  • The logging destination of FlowDB can now be configured at init by setting the FLOWDB_LOG_DEST environment variable, valid options are stderr, csvlog, and jsonlog.
  • The location inside the container of FlowDB's automatically generated config file has changed to /flowdb_autoconf/$AUTO_CONFIG_FILE_NAME.

1.26.0

Changed

  • FlowDB now enables partitionwise aggregation planning by default
  • FlowDB now uses a default fillfactor of 100 for cache table indexes
  • EXCLUDE constraint on FlowDB infrastructure.cell_info table requires unique mno_cell_id across all simultaneously-valid cells per cells_table_version, regardless of to_include. #6626

Fixed

  • Queries that have multiple of the same subquery with different parameters no longer cause duplicate scopes in tokens. #6580
  • FlowETL QA checks count_imeis, count_imsis, max_msisdns_per_imei and max_msisdns_per_imsi now only count non-null IMEIs/IMSIs. #6619

  • FlowETL get_qa_checks no longer attempts to create duplicate tasks for QA checks defined in the DAG folder. #6494

Removed

1.24.0

Added

  • Added new get_qa_checks method to flowmachine Connection objects #2704

Fixed

  • FlowAuth now runs migrations correctly on startup. #6480

1.23.0

Changed
