Jiayu Shen updated CARBONDATA-4051:
-----------------------------------
Description:
The requirement is from SEQ，related algorithms are provided by group Discovery.
1. Replace geohash encoded algorithm, and reduce required properties of CREATE
TABLE. For example,
{code:java}
CREATE TABLE geoTable(
timevalue BIGINT,
longitude LONG,
latitude LONG) COMMENT "This is a GeoTable"
STORED AS carbondata
TBLPROPERTIES ($customProperties 'SPATIAL_INDEX'='mygeohash',
'SPATIAL_INDEX.mygeohash.type'='geohash',
'SPATIAL_INDEX.mygeohash.sourcecolumns'='longitude, latitude',
'SPATIAL_INDEX.mygeohash.originLatitude'='39.832277',
'SPATIAL_INDEX.mygeohash.gridSize'='50',
'SPATIAL_INDEX.mygeohash.conversionRatio'='1000000'){code}
2. Add geo query UDFs
query filter UDFs :
* _*InPolygonList (List<String> polygonList, OperationType opType)*_
* _*InPolylineList (List<String> polylineList, Float bufferInMeter)*_
* _*InPolygonRangeList (List<Long []> RangeList, **OperationType opType**)*_
*operation only support "OR", "AND"*
geo util UDFs :
* *GeoIdToGridXy(Long geoId) :* *Pair<Integer, Integer>*
* *LatLngToGeoId(**Long* *latitude, Long* *longitude) : Long*
* *GeoIdToLatLng(Long geoId) : Pair<Double, Double>*
* *ToUpperLayerGeoId(Long geoId) : Long*
* *ToRangeList (String polygon) : List<Long []>*
3. Currently GeoID is a column created internally for spatial tables, this PR
will support GeoID column to be customized during LOAD/INSERT INTO
