MinGuang Zhang commented on ATLAS-4884:
---------------------------------------
[~madhan] - In my understanding, atlas works as a type system. User can use
atlas to build their system as metadata store, define new type and entity
convenient for their their business system Bill Management、Staff Management ...
and finally metadata stored in atlas.
For those use case, user will be more concern their user defined properties.
like bill_total, paid_tax, staff_working_years ...
So an convenient and brief user defined properties search in DSL will be very
useful.
Maybe like this or some tips:
{code:java}
>From Bill where __bill_total > 20 and __paid_tax < 3 {code}
> approximateCount confused

> atlas should return search result total exactly when user post some search
> Conditions, like query string and filter. Is using approximateCount as
> total? but approximateCount make me confused.
> a general scene： i want the total of search result for page i one request.
> but now i should recall api to add limit (eg: 100000+) .
> the bad way: to reduce paramaters for get all and return hurge data for
> calculate.
>
> {*}Problem 1{*}:
> the response of post "/search/basic" api.
> see picture1 , i'm not add filter and set search text to find the hive_table
> contains my custom attributes, the approximateCount is correct。 by the way,
> is DSL support find __customAttribute?? how to do?

> also i can't using the entities size for work when the limit paramters
