Eclipse apparently doesn't scan build output looking for -D flags, so
having the value actually appear in a header is nicer for those of us
using IDEs.
Previously <curl/curl.h> was included even if compiled --without-libcurl.
This can fail when libcurl headers are not there. This commit guards this
include by checks for HAVE_LIBCURL.
Adds ```citus.enable_statistics_collection``` GUC variable, which ```true``` by default, unless built without libcurl. If statistics collection is enabled, sends basic usage data to Citus servers every 24 hours.
The data that is collected consists of:
- Citus version
- OS name & release
- Hardware Id
- Number of tables, rounded to next power of 2
- Size of data, rounded to next power of 2
- Number of workers
This commit provides the support for window functions in subquery and insert
into select queries. Note that our support for window functions is still limited
because it must have a partition by clause on the distribution key. This commit
makes changes in the files insert_select_planner and multi_logical_planner. The
required tests are also added with files multi_subquery_window_functions.out
and multi_insert_select_window.out.
We should skip if the process blocked on the relation
extension since those locks are hold for a short duration
while the relation is actually extended on the disk and
released as soon as the extension is done. Thus, recording
such waits on our lock graphs could yield detecting wrong
distributed deadlocks.
We sent multiple commands to worker when starting a transaction.
Previously we only checked the result of the first command that
is transaction 'BEGIN' which always succeeds. Any failure on
following commands were not checked.
With this commit, we make sure all command results are checked.
If there is any error we report the first error found.
Basically we just care whether the running version is before or after
PostgreSQL 10, so testing the major version against 9 and printing a
boolean is sufficient.
When a table and it's shards are dropped, and afterwards the same
shard identifiers are reused, e.g. due to a DROP & CREATE EXTENSION,
the old entry in the shard cache and the required entry in the shard
cache might be for different tables.
Force invalidation for both old and new table to fix.
Citus can handle INSERT INTO ... SELECT queries if the query inserts
into local table by reading data from distributed table. The opposite
way is not correct. With this commit we warn the user if the latter
option is used.
