Arina Ielchiieva updated DRILL-7073:
------------------------------------
Description:
CREATE SCHEMA command improvements:
1. add format
2. add default
3. add column properties
TupleSchema / ColumnMetadata improvements:
1. add properties map;
2. add format;
3. add default from string literal;
4. add ser / de methods.
Example:
{noformat}
create schema
(col date not null format 'yyyy-MM-dd' default '2018-12-31' properties {
'prop1' = 'val1', 'prop2' = 'val2' })
path '/path/to/schema'
{noformat}
The following schema will be created:
{noformat}
{
"schema" : {
"columns" : [
{
"name" : "col",
"type" : "DATE",
"mode" : "REQUIRED",
"format" : "yyyy-MM-dd",
"default" : "2018-12-31",
"properties" : {
"prop2" : "val2",
"prop1" : "val1"
}
}
]
},
"version" : 1
}
{noformat}
