Jonathan A. Sternberg	9d049c4b62	Optimize the spread function to process points iteratively instead of in batch	2018-04-30 11:25:29 -05:00
Jonathan A. Sternberg	d42062def2	Add technical analysis algorithms This adds numerous technical analysis algorithms: * exponential_moving_average * double_exponential_moving_average * triple_exponential_moving_average * relative_strength_index * triple_exponential_average * kaufmans_efficiency_ratio (commonly referred to as just "Efficiency Ratio") * kaufmans_adaptive_moving_average * chande_momentum_oscillator (both the common 'smoothed' version, and the ta-lib version)	2018-04-23 22:27:21 -04:00
Jonathan A. Sternberg	41bc1ab241	Use a null placeholder for NaN results This ensures that NaN gets serialized as a null value and that it does not get replaced with the fill value.	2018-03-27 08:44:44 -05:00
Stuart Carnie	f3d45ba301	influxdata/influxdb/influxql -> influxdata/influxql	2017-10-30 14:40:26 -07:00
Jonathan A. Sternberg	0ef94e0cf0	Add unsigned iterators for all types This allows unsigned data to be queried from the storage engine. Binary math is not yet implemented for unsigned types.	2017-09-18 15:09:10 -05:00
Jonathan A. Sternberg	9a2357c2c0	Separate the query engine into a separate package This change provides a clear separation between the query engine mechanics and the query language so that the language can be parsed and dealt with separate from the query engine itself.	2017-08-16 13:38:43 -05:00
