Hi everyone,
I'm not fully understand what does this means when I access
The API return
"xyzreport_20161025" : {
"primaries" : {
"fielddata" : {
"memory_size_in_bytes" : 15704336,
"evictions" : 0,
"fields" : {
"_type" : {
"memory_size_in_bytes" : 15704336
}
}
}
},
"total" : {
"fielddata" : {
"memory_size_in_bytes" : 15704336,
"evictions" : 0,
"fields" : {
"_type" : {
"memory_size_in_bytes" : 15704336
}
}
}
}
},
What is actually _type field means? I'm sure that my mapping schema does not have this field, is this mean ES internal field?
Why and when ES will use this _type for fielddata?
Please share your idea and experience.
Many thanks
