Performance testing identified that the decoding of provider GetSchema responses took a non trivial quantity of time and memory. This removes the problematic global provider schema cache and instead manages the primary cache as a field passed to the GRPC providers. This, combined with better handling of the GetProviderSchemaOptional=false case, dramatically reduces the overhead of running providers. The primary downside to this approach as it currently stands is that a new contextPlugins is created for each backend operation (validate, plan, apply). This will start up and then subsequently quickly shut down an already cached provider. In practice, this is still a performance win and should be addressed in a subsequent PR that overhauls the provider and provisioner management interfaces in a more comprehensive fashion.

OpenTofu
OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu can manage existing and popular service providers as well as custom in-house solutions.
The key features of OpenTofu are:
-
Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
-
Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.
-
Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
-
Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
