Onder Kalaci d5472614df Use non-data connection for intermediate results 
Make sure that intermediate results use a connection that is
not associated with any placement. That is useful in two ways:
    - More complex queries can be executed with CTEs
    - Safely use the same connections when there is a foreign key
      to reference table from a distributed table, which needs to
      use the same connection for modifications since the reference
      table might cascade to the distributed table.

mehmet furkan şahin 2b2ce036eb create_distributed_table honors sequential mode 2018-06-19 17:33:45 +03:00
Onder Kalaci 8f5821493a Implement C interface for setting GUC 
We need the ability to switch to sequential mode (e.g.,
 SET LOCAL citus.multi_shard_modify_mode = 'sequential'). This
commit enables that.

for this functionality.

Add node_conninfo GUC and related logic 
To support more flexible (i.e. not at compile-time) specification of
libpq connection parameters, this change adds a new GUC, node_conninfo,
which must be a space-separated string of key-value pairs suitable for
parsing by libpq's connection establishment methods.

To avoid rebuilding and parsing these values at connection time, this
change also adds a cache in front of the configuration params to permit
immediate use of any previously-calculated parameters.

Onder Kalaci a5370f5bb0 Realtime executor honours multi_shard_modify_mode 
We're relying on multi_shard_modify_mode GUC for real-time SELECTs.
The name of the GUC is unfortunate, but, adding one more GUC
(or renaming the GUC) would make the UX even worse. Given that this
mode is mostly important for transaction blocks that involve modification
/DDL queries along with real-time SELECTs, we can live with the confusion.

Onder Kalaci df44956dc3 Make sure that sequential DDL opens a single connection to each node 
After this commit DDL commands honour `citus.multi_shard_modify_mode`.

We preferred using the code-path that executes single task router
queries (e.g., ExecuteSingleModifyTask()) in order not to invent
a new executor that is only applicable for DDL commands that require
sequential execution.

notices a failure in the COMMIT callback.

Brian Cloutier 4c2bf5d2d6 Move call to RemoveIntermediateResultsDirectory 
Errors thrown in the COMMIT handler will cause Postgres to segfault,
there's nothing it can do it abort the transaction by the time that
handler is called!

RemoveIntermediateResultsDirectory is problematic for two reasons:
- It has calls to ereport(ERROR which have been known to trigger
- It makes memory allocations which raise ERRORs when they fail

Once the COMMIT process has begun we don't use the intermediate results,
so it's safe to remove them a little earlier in the process. A failure
here will abort the transaction. That's pretty unnecessary, it's not
that important that we remove the results, but it's still better than a
crash.
