mysql – RDS Aurora Serverless "Parameter Groups"

I have a RDS Aurora Serverless MySQL cluster and I am trying to change a MySQL setting (Connection timeout). Normally, you would use a parameter group to set the value in the DB instance. However, since this is without a server, all instances are managed by AWS. So it seems that I can only configure the cluster.

Is there a way to set the parameter set used by instances created by AWS?

postgresql – AWS Aurora Database corruption

I'm using Aurora Postgres and I've noticed that the Maximum Used Transaction IDs are growing strongly. Attempting to manually suck the tables that were not automatically vacuumed led to the following errors:

sql> VACUUM sales.hist_status
[2019-01-06 15:22:44] [58P01]    ERROR: Unable to access transaction status 247756185
[2019-01-06 15:22:44] Detail: CLOG segment 29 does not exist: No such file or directory.

sql> VACUUM sales.hist_items
[2019-01-06 15:22:55] [XX001]    ERROR: xmin 235941673 from found before relfrozenxid 256796328

Running through these errors indicates corruption of the database. What should I do?

App Windows – Aria Sounds Aurora Choir v2 CONTACT | NulledTeam UnderGround

Aria sounds like Aurora choir v2 CONTACT | 6.3 GB

The Aurora Choir is an elegant and powerful choral sample library for contact, setting a milestone for Aria Sounds as the culmination of many hours of work, study and optimization.

, The library contains both sopranos and altos (separate instruments for maximum control) and has an absolutely impressive legato tone. In addition, it has short syllables, which are arranged in a very well-playable sequencer. Simply arrange your phrase in the sequence and play away – the choir automatically sings the entered syllables.
Several legato modes with multiple dynamics
The choir contains four real legato modes (ah, eh, ih, and oh) sampled on multiple dynamic layers. This results in a total of 8 REAL sampled legato sets for absolute realism and variation. In addition, there are a total of twenty-four different syllable shorts that are sequential in the graphical user interface and sampled at three dynamic levels, giving a total of 72 variations per short note.
Four microphone positions (48 kHz / 24 bit)
The choir was recorded in a medium-sized hall for a flawless and clear sound. Four microphone positions ensure that no part of the wonderful sound of the singers is wasted. Select or create a personal mix from the four available positions. The positions are sorted from close to far, and you even have the option to switch between condenser microphones and band microphones (for a darker and warmer sound). If you're looking for a more reverberant sound, there's a reverb slider on the user interface, and you'll be glad to hear that this library handles external reverb very well.

Aurora MySql 5.7 killed processes does not die

We are using AWS Aurora MySQL and have recently switched to MySQL 5.7. After upgrading to this release, issues with DDL statements were displayed. The processes in which these statements are executed depend only on the "wait for table metadata lock" state. If we tried to cancel the process, the status changes to "Killed," but the process is still running (we can see it when "show full processlist" is executed). We waited 24 hours and the process was never stopped. At the end we restarted the DB. But we can not do that every time. Has anyone had the same problem with MySQL 5.7 and somehow solved it?

Many Thanks,
