Hi All,
I have created a wiki entry for entity level locks in asterixdb at =
https://cwiki.apache.org/confluence/display/ASTERIXDB/Entity+locks+in+Aste=
rixDB =
<https://cwiki.apache.org/confluence/display/ASTERIXDB/Entity+locks+in+Ast=
erixDB>=20
It is pretty primitive at this stage but with your contribution, it can =
be improved quite a bit.
The goal of this entry is to act as a reference to our locking for =
developers, testers, and users as well. We would like to use it as the =
basis as we're adding unit tests to locking within different cursors as =
we're adding unit tests to those.

Special mention to @Taewoo to take a look :)

Cheers,
~Abdullah.=

Dear devs,
I was going over implementations of ILogicalOperator.isMap in our code =
base and here is the breakdown:

isMap()

true:
-Assign
-AbstractReplicateOperator
-AbstractUnnestOperator
-ExchangeOperator
-InsertDeleteUpsertOperator
-LimitOperator
-ProjectOperator
-SelectOperator


false:
-Order
-Aggregate
-RunningAggregate
-AbstractBinaryJoin
-AbstractOperatorWithNestedPlans
-DataSourceScanOperator
-DistinctOperator
-DistributeResultOperator
-EmptyTupleSourceOperator
-IndexInsertDeleteUpsertOperator
-IntersectOperator
-MaterializeOperator
-NestedTupleSourceOperator
-ScriptOperator
-SinkOperator
-TokenizeOperator
-UnionAllOperator
-WriteOperator
-WriteResultOperator

As I understood at some point is that isMap means (does this operator =
map input tuples to output tuples without blocking?). I am not sure how =
accurate this description is but it clearly introduces a problem as:

* InsertDeleteUpsertOperator.isMap() -> true
* IndexInsertDeleteUpsertOperator.isMap() -> false

Moreover,=20
TokenizeOperator.isMap() -> false
AbstractUnnestOperator.isMap() -> true

while clearly, as per the definition above, these two operators should =
have the same output: true

Can someone solve the mystery?
Once this is solved, I will add a wiki entry to explain this flag.

Cheers,
Abdullah.=

The attribute is called canDecreaseCardinality.

Hi,

Esri geometry-api version 2.0.0 have been released in maven central[1]. Now
I am able to use it without any license issues[2].

[2] https://asterix-gerrit.ics.uci.edu/#/c/1838

Thank you.
Sincerely,
Riyafa

It seems that it is set to true when the operator has the two =
properties:
1. A mapping from no more than one input tuple to one or more output =
tuples can be established.
2. Is not blocking operator.


As per this, we can clearly see that:
- IndexInsertDeleteUpsertOperator should have isMap() set as true
- TokenizeOperator should have isMap() set as true

Did I get anything wrong here?

As AsterixDB evolves, and additional features are added - e.g., DISTINCT 
aggregate support, or properly implemented query-bodied functions, 
supporting two query languages is hugely expensive:  Updating two 
grammars, parsers, rules, tests, ... IMO it is time to let go of AQL as 
an externally supported interface to AsterixDB and only have SQL++ going 
forward.  I think "everyone" has migrated - and if not we should force 
that migration.  (Cloudberry is on SQL++ nowadays, BAD is on SQL++ 
nowadays, ...)  Any objections?  If not, I think we should make this 
decision officially and stop putting energy into carrying the AQL legacy 
around with us.  Thoughts?

Or possibly how to retire it and then re-do similarity joins using the 
join infrastructure ideas discussed a year or so ago, perhaps.  (We 
should think about whether or not the time it would take to do SQL+++ 
might be better used to not use that approach anymore - it was an 
interesting experiment at the time it was done, but it's probably worth 
having a revisiting discussion 5 years later - and also whether the 
algorithm as it was invented is still the preferred one to support - 
though the required SQL+++ query would surely be an interesting SQL++ 
optimizer test... :-))

Hi devs,
I just added a new entry in our wiki for the index components lifecycle. =
https://cwiki.apache.org/confluence/display/ASTERIXDB/Index+Component+Life=
cycle =
<https://cwiki.apache.org/confluence/display/ASTERIXDB/Index+Component+Lif=

Hope it helps new comers and existing community members.

Please, help keep it maintained when you make any code changes.

Cheers,
Abdullah.=

Hi Devs,

In line with earlier major structural refactorings of =
storage/index-related code [1] I would like to propose a next step in =
this cleanup [2].
The main problem that I tried to solve with this patch is that code =
responsible for LSM disk/memory component lifecycle (creation, =
destruction, bulkloading, etc) is smeared across fabric methods in =
appropriate index implementations, while much of it is duplicated =
between various types of index components (bTrees, externalBTrees, =
externalBTreesWithBuddyBTree, rTrees, antimatterRTrees, invertedIndexes, =
etc). Moreover all these different disk\memory component implementations =
have a lot of commonality in how they manage lifecycle of their parts =
(main indexes, bloom filters, buddyBTrees\deletedKeysBTrees).

This change removes much of boilerplate from LSM component-handling code =
and relies on more object-oriented design to bring in the logic of a =
particular element of the component into one place.
It also introduces a composable method of assembling bulkload pipelines, =
allowing to create a chain of operators,  responsible for bulkloading a =
piece of component, and easily extend this pipeline with additional =
operations (calculating stats\inferring schema\etc).

If your are interested or have an opinion on how this part of the =
codebase should be structured (or it will break all your code in a =
private branch ;)), please have a look [2].

Best regards,

Subject: inserting into an autogenerated key dataset from a query result

Hi all,
I'm seeing a strange issue when inserting into a dataset with an
autogenerated key the result of a query. I was wondering if anyone has had
success with such a case. I have a simple example below which fails on
master (The full JIRA issue is here:
https://issues.apache.org/jira/browse/ASTERIXDB-2101)


drop dataverse channels if exists;
create dataverse channels;
use channels;
create type result as {
  id:uuid
};
create type subscriptionType as {
  subscriptionId:uuid,
  param0:int
};
create dataset roomRecordsResults(result)
primary key id autogenerated;
create dataset roomRecordsSubscriptions(subscriptionType)
primary key subscriptionId autogenerated;
use channels;
insert into channels.roomRecordsResults (
  select sub.subscriptionId
  from channels.roomRecordsSubscriptions sub
);

Note that this works on the release from a couple of weeks ago, so this 
is a regression that got missed by our tests (surprise!) it seems.

Hi all,

I'm a PhD student at UCR advised by Dr Eldawy and I have started working 
on AsterixDB.
Since I have updated to the last version, I cannot even run the SQL++ 
examples from the Asterix website. More specific, when I'm trying to 
create datasets/indexes, I'm getting the following errors (copy-paste 
from IntelliJ IDE):

Cleaned and rebuilt several times with no result. Any ideas why I'm 
getting these errors?
(I'm sorry for the long email and if the answer is obvious, but it's not 
a while since I had started working with AsterixDB)

Thank you in advance,
Zacharias Chasparis

Using commandline, from the root asterixdb dir:

cd asterixdb/asterix-runtime/
mvn clean install -o -DskipTests

Then try again and it should work. This error is due to not having IDE =
integration for the source code generation part of asterixdb.

Let's know if you need further help,
Abdullah.

Hi,

apparently something went wrong with one of the recent BAD changes [1]:
The Gerrit review has been merged, but the change is not in the ASF git 
repository [2] (or the GitHub mirror [3]).
How can we fix this?

Thanks,
Till

Hi Devs,

Recently I was facing a problem with the IntersectOperator. Previously
we've used the IntersectOperator to intersects primary keys returned from
searching multiple secondary indexes, and use them to perform primary key
lookups. However, with component Id-based acceleration, each primary key
returned from a secondary index would carry a component Id (which is two
numbers). Thus, inside the IntersectOperator, we only intersect the primary
keys, while need to select a proper component Id based on these inputs. For
example, for 3 input tuples (a, [1, 3]), (a, [0, 2]) and (a, [2, 2]), where
'a' is the primary key and the interval is the component Id, we may return
(a, [2, 2]) as the output of the intersection.

Thus, my question is that *is there any function interface inside AsterixDB
which takes a list of input tuples and produce a tuple as a result*? With
this functionality, we can devise strategies to select the best component
Id for each primary key. Any help is appreciated!

Best regards,
Chen Luo

NVM, I think I can implement a customized aggregate function for this
purpose (though it's semantics is slightly different from traditional SQL
aggregate functions which only produce one result value). Please correct me
if my understanding is wrong...

Subject: Strange error trying to run Asterix master

Hi all,
I've been stuck for some time now trying to get master Asterix to debug
correctly for me in Eclipse on my machine. It seems to deal with the class
generation being done by maven, but that's as far as I can see so far. No
one I've talked to has a similar issue, so I was wondering if anyone from
the community at large has had such an issue. It manifests itself when
tying to create the evaluator for a function. The stack trace is attached
below. If anyone has seen such an issue, I would love to get any advice you
may have.

I got the same issue before. I did "clean project" and the issue seems to
be resolved.

Hi Devs,

With the patch in [1], we will no longer support using '#'  for line
comment. You may use '--' or '//' as alternatives. Meanwhile, backquoting
function name for invoking external UDF in SQLPP is not enforced now. You
can use either

testlib#getCapital("England") or `testlib#getCapital`("England")

to invoke your external UDF.

Best,
Xikui

Hi Steven,

I was using Eclipse (on mac) to debug AsterixDB's code, and things work
well for me. After switch to another branch, I think we need to run "mvn
clean install" to rebuild class files, and in the meanwhile need to refresh
the workspace in Eclipse to rebuild things in Eclipse.

Best regards,
Chen Luo
