Is `T` ever not ` amp str`

Question

Is `T` ever not ` amp str` <https github com delta io delta rs blob main rust src partitions rs L12>

KyJah Keys · Answer

Theoretically it could be any valid column value in the schema

KyJah Keys · Answer

However I think you re right since the only thing it is ever compared against is ` amp str` since `DeltaTablePartition` only has ` amp str` values

Cole MacKenzie · Answer

Yeah that is true There is also <https github com delta io delta rs blob main rust src partitions rs L40 L65|this function> which indicates it does a literal type comparison but I am unsure of the actual need for it

Cole MacKenzie · Answer

Based on <https github com delta io delta blob master PROTOCOL md partition value serialization> I guess the native type comparison would be needed to compare times and numbers as since as a string numbers can t be compared

Cole MacKenzie · Answer

I guess times can be string compared as well though since they are zero padded So only numeric types need that parsing step
