ISSUE: https://github.com/FirebirdSQL/firebird/issues/7537
|
|
TITLE: Add ability to query current value of parallel workers for an attachment
|
|
NOTES:
|
|
[03.04.2023] pzotov
|
|
::: NB :::
|
|
This is INITIAL version of test.
|
|
It checks only *ability* to query values from mon$attachments and rdb$get_context.
|
|
It does NOT check tag fb_info_parallel_workers because this is not yet implemented
|
|
(BTW, 'isc_dpb_parallel_workers' also not yet avaliable in the firebird-driver).
|
|
==============
|
|
doc/README.parallel_features.txt:
|
|
Default value is 1 and means no use of additional parallel workers. Value in
|
|
DPB have higher priority than setting in firebird.conf.
|
|
...
|
|
ParallelWorkers - set default number of parallel workers that used by user attachments.
|
|
Could be overriden by attachment using tag isc_dpb_parallel_workers in DPB.
|
|
==============
|
|
|
|
Checked on intermediate snapshot 5.0.0.1001.
