I'm not sure if it's still correct, but based on my understanding,
OptimizedHybridHashJoinOperatorDescriptor does the role reversal
optimization which was done by Pouria, while
HybridHashJoinOperatorDescriptor was the old implementation before Pouria's
work and probably could be deleted.

Here you go:

As a temporary workaround, you can do the following before your query:

If you want to fix this, please take a look at

What you can do is to not inline if there is a non-pure function call

In the optimizer (the asterixdb/algebricks level), we don't have

For (1), the eventual goal is to only have underscores.
Currently it's a transition period -- all docs are based on underscores.
For new functions, it's good to only support underscores.

Hi Taewoo,
Are those fulltext search syntax extensions are only a syntactic sugar
(i.e., surface) thing that is translated into functions?
In a not-too-distant-future, we will need to surface fulltext search in
SQL++, probably using the same functions like Oracle. If the AQL fulltext

Currently you can push Project into the source but not Select.
You're welcome to enhance IMetedataProvider to support that. You can take

Hi committers,
The current code style (http://asterixdb.apache.org/dev-setup.html)
that we use clears line breaks for javadocs.
I'm proposing a one line minor change in the code style:
Attached is the updated code style file. Please reply this message if
you have different though

Steven,
Can you add a regression test before you closing that issue?
(Typically, fixing ASTERIXDB- should have a test case in the
change.)
Thanks!

It seems there is some existing instance on the docker instance and hence
it complains that the port is already used.

Hi Vignesh,
We're still working on finalizing the SQL++ doc for AsterixDB. Here is
a draft that you can take a look:
https://github.com/sigmod/sqlpp/blob/master/document.md
The ETA of the completed version would be next week.
Thanks!

Hi Taewoo,
I have a few questions regarding to your index-only change (I'm cc-ing to
dev just in case more people are interested in the topic.):
1. Is there any design doc or write up for the index-only change?
2. Do you have ddls/queries that are designed for the index-only
performance testing?
>> Is there any database or SQL implementation supporting that?
Ok, it turns out MySQL supports that, while Postgres, MS SQL and Hive do
not have that.

Very cool!!
It seems that there is an assumption that returned results are records?
For example, you can try the following query:
Q1:
for $m in dataset Metadata.Dataset
return $m.DatasetName;
Q2:
1+1;

Does anyone know/have the dataset for reproducing ASTERIXDB-1061?
https://issues.apache.org/jira/browse/ASTERIXDB-1061
https://code.google.com/archive/p/asterixdb/issues/918
It seems to be some issue dataset.
