Swap serialization in DatabaseBackendFactory

Why you need such hack instead of changing serializer at PHP level? It looks like tremendous overhead for build-in operation

I think we should do that in core:

#3014514: Make igbinary the default serializer if available, it saves 50% time on unserialize and memory footprint

Per @andypost I do not need this patch if I update my services.yml to use the proper serializer. Is my interpretation correct?

As core 11.0/10.3 has serializer configurable #839444: Make serializer customizable for Cache\DatabaseBackend

maybe it needs follow-up to fix arguments

Hello,

As the 8.x-1.x branch is no more supported and as the 2.0.x module has a different approach, is this issue still relevant? Could it be closed?

D10.3/11 added #839444: Make serializer customizable for Cache\DatabaseBackend.
Does it have any impact on this module version 2.x?

I think we need to add PECL extension to CI images to make ball roll

now all 8.3-8.5 images has igbinary PECL enabled
