Hi all,
We are planning to remove "FACET" (this type is used to categorize/group,
to get unique values and to drill-down) from indexing data types and we
will introduce an attribute to mark other data types as a FACET or not.
Earlier FACETs can be defined only for STRING fields and even if we define
a STRING as a FACET, then we will not be able to search it as a STRING
field. With this change, any data type field can be marked as a FACET and
then the field can be used as a FACET and as the usual data type as well.
This change will not affect the older DAS capps or event-store
configurations; It will be backward compatible with previous DAS versions
(3.0.0 and 3.0.1). However if you try to get the Schema of a table using JS
APIs, REST APIs or the Webservice, FACET type will not be there. A
attribute called "isFacet" is used to identify the FACETed fields. See
below for an example.
*Older schema*
{
"columns" : {
"logFile" : { "type" : "STRING", "isIndex" : true,
"isScoreParam" : false },
"level" : { "type" : "DOUBLE", "isIndex" : true, "isScoreParam"
: false },
"location" : { "type" : "FACET", "isIndex" : true,
"isScoreParam" : false } },
"primaryKeys" : ["logFile", "level"]
}
*Equivalent new schema*
*{ "columns" : { "logFile" : { "type" : "STRING", "isIndex" :
true, "isScoreParam" : false, **, isFacet : *false
* }, "*level*" : { "type" : "DOUBLE", "isIndex" : true,
"isScoreParam" : false, **, isFacet : *false* }, *
* "location" : { "type" : "*STRING*", "isIndex" : true,
"isScoreParam" : false, isF*acet : true
* } }, //FACET field is removed "primaryKeys" : ["logFile", "*level
*"] }*
