Onder Kalaci 4d70c86645 Leaf level recursive planning for non colocated subqueries 
With this commit, we enable recursive planning for the subqueries
that are not joined on the distribution keys.

Onder Kalaci e998703ff8 Enable restriction eq. checks for top level set operations 
We used to only support pushdownable set operations inside a
subquery, however, we could easily expand the restriction
checks to cover top level set operations as well.

Onder Kalaci e8aa532a90 Refactor checks for distribution key equality

function order rules etc.

Merge pull request #1989 from citusdata/refactor_restriction_logic 
Some code refactoring and performance improvements for restriction equivalences
 2018-02-12 20:01:35 +03:00
Onder Kalaci 94c5ac6ebb Remove duplicate join restrictions 
We use PostgreSQL hooks to accumulate the join restrictions
and PostgreSQL gives us all the join paths it tries while
deciding on the join order. Thus, for queries that have many
joins, this function is likely to remove lots of duplicate join
restrictions. This becomes relevant for Citus on query pushdown
check peformance.

Murat Tuncer 678223224b Update regression test output expectation based on recent PG10 change 2018-02-06 14:44:55 +03:00
Murat Tuncer 901b543e20 Fix count distinct using field select on top level query 
We were allowing count distict queries even if they were
not directly on columns if the query is grouped on
distribution column.

When performing these checks we were skipping subqueries
because they also perform this check in a more concise manner.
We relied on oid SUBQUERY_RELATION_ID (10000) to decide if
a given RTE relation id denotes a subquery, however, we also
use SUBQUERY_PUSHDOWN_RELATION_ID (10001) for some subqueries.

We skip both type of subqueries with this change.

Brian Cloutier e6ebfc1f53 Remove VLA from UpdateNodeLocation 2018-02-01 10:30:41 -08:00
Brian Cloutier a2ed45e206 Remove variable length arrays 
VLAs aren't supported by Visual Studio.

- Remove all existing instances of VLAs.
- Add a flag, -Werror=vla, which makes gcc refuse to compile if we add
  VLAs in the future.
 2018-02-01 10:30:41 -08:00
Brian Cloutier 2efe80ce55 CheckForDistributedDeadlocks no longer uses a VLA 
- variable length arrays (VLAs) do not work with Visual Studio
- fix an off-by-one error. We incorrectly assumed there would always at
  least as many edges as there were nodes.
- refactor: reduce scope of transactionNodeStack by moving it into the
  function which uses it.
- refactor: break up the distinct uses of currentStackDepth into
  separate variables.

GetNextNodeId() incorrectly called PG_RETURN_DATUM 
- Also stabilize the output of a multi_router_planner test
 2018-01-29 15:32:36 -08:00
Brian Cloutier 61a6b846b9 Refactor: use a temporary timestamp variable 
It's against our coding convention to call functions inside parameter
lists; when single-stepping with a debugger it's difficult to determine
what the function returned.

That wouldn't be good enough reason to change this code but while
porting Citus to Windows I ran into this line of code.
assign_distributed_transaction_id was called with a weird timestamp and
I wasn't able to find the problem without first making this change.
