This is intended to help downstream libraries not need the engine to check for typing, as well as clear up some transient errors that can occur with certain engines on large machines. I have also added a warning message that informs the user how to clear the message. We will likely need a way to suppress these errors, because many users will not care about them and potentially want to suppress. We will probably also want to add a benchmarking page on best practices for benchmarking because this change can give the impression of a performance degradation on data ingestion even though nothing is changing from that perspective.

There was a mix of use cases for modifying the external metadata and internal metadata, and some problematic components of these APIs that could hide bugs. The implementation has been updated to ensure that these bugs do not resurface. Previously, the internal and external indices were compared, and then updated according to some arguments that were passed in. This is not scalable because collecting the indices is expensive. The possible bugs hidden in this implementation decision could end up being very difficult to detect: it implicitly updates the internal or external indices based on a somewhat cryptic string pattern combined with a boolean flag. Another very large issue is that sometimes external indices are updated based on the partition lengths metadata. This was likely done to solve a use case of not using the APIs properly. This implementation has been removed and replaced with something more explicit. If the internal indices need to be updated, they are updated explicitly via existing APIs. Likewise if external indices need to be updated, they are updated with a different API. Several QueryCompiler APIs had to be reverted because they were misusing the ReductionFunction or MapReduceFunction, thus the need for the implicit modification of metadata. When this implicit modification was removed, these APIs no longer worked, and so were reverted until they can be reimplemented using correct APIs. The following APIs were reverted as a part of this commit: * `is_monotonic_increasing` * `is_monotonic_decreasing` * `value_counts` * `searchsorted` * `dt_tz` * `dt_freq` Signed-off-by: Devin Petersohn <devin.petersohn@gmail.com> * REFACTOR-modin-project#2648: Remove debug code Signed-off-by: Devin Petersohn <devin.petersohn@gmail.com> * REFACTOR-modin-project#2648: Fix explicit rename Signed-off-by: Devin Petersohn <devin.petersohn@gmail.com> * DOCS-2653: Fix links in Modin's documentation (modin-project#2654) Signed-off-by: Alexey Prutskov <alexey.prutskov@intel.com> * FEAT-modin-project#2663: Add algebraic operator `from_labels` (modin-project#2665) Resolves modin-project#2663 This operator is necessary for efficient `reset_index` operations.
