Description

• Support multi vid_ref_expression in from clause.
• Support uuid in where clause.

issue from vesoft-inc/nebula-java#81

Describe the feature:
We already dropped ganglia in version 0.6.0.

Describe a specific use case for the feature:
It be good to remove these changes, to prevent confusion.

This will be a breaking change so needs to be done with a major release.

Currently OperationDetail and OperationField are inner classes within OperationServiceV2. These should be in their own outer classes for ease of serialisation and consistency.

If you do object.association.distinct.other_association, the distinct goes away.

This is probably good for the simple implementation, but we could have a WITH DISTINCT automatically go in there on the second association

2 * X queries vs. 1

currently a single transaction with a batch X of documents does 2 * X SQL queries.
it looks whether the document exists first and then inserts or updates it:

(defrecord JdbcDocumentStore [ds dbtype]
  db/DocumentStore
  (submit-docs [this id-and-docs]            ;;    batch of documents
    ;; ...
    (doseq [[id doc] id-and-docs
      (if-not (do

all of the cors_catch wrapper stuff should be moved to http_request_expansion

Per discussion in #2743 this class is mis-named.

Also, rename LinkStreamValue to just plain LinkStream.
