| 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.= |

| My understanding is that isMap() is set to true when the cardinality of the |
| input may not be equal to the the cardinality of the output. To settle this |
| issue, I come up with one explicit property in my Limit Push down branch. |
| 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]. |
| |

| |
| Thank you. |

| 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:Â 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? |

| interesting experiment at the time it was done, but it's probably worth |
| having a revisiting discussion 5 years later - and also whether the |

| though the required SQL+++ query would surely be an interesting SQL++ |
| optimizer test... :-)) |

| 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]. |
