  5. WP 3 – CALS Extraction API Backport(In Progress) • Purpose: minimize the impact on existing CALS user applications • Work foreseen: • Adaptation of the old code, cleanup (done) • Old CALS API - 126 methods (in progress) • Meta-data (variables, filters, etc.) needed work on NXCALS first • Data (with Spark) • Timber Users & Groups • Timber Variable Lists & Snapshots • Derived Variables • BLM Contexts (dedicated BLM names for array extraction) • CALS command line interface • Estimated to be 1 year of development (for 1 person) • Progressive releases planned for early adopters • Focusing on methods requested by the users • First release in 3 weeks with 12+ basic methods Required to phase-out CALS in 2020 LMC BE-CO-DS

  6. Methods Implemented • getDataInTimeWindow • getDataAlignedToTimestamps • getDataInTimeWindowOrLastDataPriorToWindowWithinDefaultInterval • getDataInTimeWindowOrLastDataPriorToWindowWithinUserInterval • getVariableStatisticsOverMultipleVariablesInTimeWindow • getLastDataPriorToTimestampWithinDefaultInterval • getLastDataPriorToNowWithinDefaultInterval • getLastDataPriorToNowWithinUserInterval • getLastDataPriorToTimestampWithinUserInterval • getNextDataAfterTimestampWithinDefaultInterval • getNextDataAfterTimestampWithinUserInverval BE-CO-DS

  7. Not Implemented Yet • *Fills* & *BeamModes* • Waiting for NXCALS model & migration (in progress) • *Fundamendals* • In the pipeline, NXCALS model & migration done • Meta-data search API (Variables, etc) • In progress but needed to redesign some NXCALS APIs to clean up things, fix bugs & design flaws • Crucial for Variable searches BE-CO-DS

  8. First Release? • ASAP (planned for next week) • But impacted by • Holidays • IT infrastructure upgrades (DBs & storage, Elastic, Hadoop servers, etc) • Need to constantly fix related issues • General support (CALS, NXCALS, TRACING) BE-CO-DS
