We need to make all the mapped types (that make sense to expose) available for the scripting fields api. The following is a list of all mapped field types:

Second check box shows support for source fallback.

Done

• binary (@jdconrad) Add BinaryDocValuesField to replace BytesRef (ScriptDocValues) #79760
• boolean (@stu-elastic) Script: support boolean fields in Fields API #80043
• keyword (@stu-elastic) Script: keyword fields api support #81266

• integer (@stu-elastic) Script: fields API for byte, double, float, integer, long, short #81126
• short (@stu-elastic) Script: fields API for byte, double, float, integer, long, short #81126

• scaled_float (@jdconrad) (Add scaled float to the scripting fields API #82275)
• half_float (@jdconrad) (Add half float mapping to the scripting fields API #82294)
• unsigned_long (@stu-elastic) (@jdconrad) Update Painless Fields API design to use mapped types #78950
• date (@jdconrad) Add date fields to the scripting fields api #81272
• date_nanos (@jdconrad) Add date fields to the scripting fields api #81272
• ip (@stu-elastic) Script: fields API for IP mapped type #81396
• _version (@stu-elastic) Script: fields API for x-pack version, doc version, seq no, mumur3 #81476
• sequence number (@stu-elastic) Script: fields API for x-pack version, doc version, seq no, mumur3 #81476
• version (@stu-elastic) Script: fields API for x-pack version, doc version, seq no, mumur3 #81476
• murmur3 (@stu-elastic) Script: fields API for x-pack version, doc version, seq no, mumur3 #81476
• constant_keyword (@stu-elastic) Script: fields API for x-pack constant_keyword #82292
• wildcard (@jdconrad) Make wildcard accessible from the scripting field API #82763
• flattened (@stu-elastic) Script: fields API for flattened mapped type #82590
• text - (@jdconrad) Add text field support in the Painless scripting fields API #89396

Must

(Completed)

Nice to have

• object - may require some design
• nested - requires design
• join
• integer_range Add scripting support for ranges #50190
• float_range
• long_range
• double_range
• date_range
• ip_range
• histogram
• dense_vector - (@stu-elastic) Script: Fields API for Dense Vector #83550
• sparse_vector (re-included in 8.11)

Unsupported

• alias
• aggregate_metric_double
• match_only_text
• annotated_text
• completion
• search_as_you_type
• token_count
• rank_feature
• rank_features
• percolator

Discuss

• geo_point (@jdconrad) Add a geo point field for the scripting fields api #81395 Discuss exposure of geo fields as part of the scripting fields API #82229
• geo_shape (@jdconrad) Add support for GeoShape to the scripting fields API #81617 Discuss exposure of geo fields as part of the scripting fields API #82229
• point - not supported by doc values, requires source parsing
• shape - not supported by doc values, requires source parsing

The following links have tests that may be re-usable as we add in certain basic field types:

• possible tests for boolean, long, double, and date
• possible tests for boolean, long, double, and date
• possible tests for boolean, long, double, and date
• possible tests long, double
• possible tests for double
• possible re-use of several field classes populated w/ data for other tests
• possible re-use of some code for conversion testing
• possible tests for unsigned long
• possible conversion tests for unsigned long
