Prefer instanceof to getClass when implementing Object#equals.

Importing nested classes/static methods/static fields with commonly-used names can make code harder to read, because it may not be clear from the context exactly which type is being referred to. Qualifying the name with that of the containing class can make the code clearer. Here we recommend using qualified class: AwsTransactionHandle.

The field 'LEGACY_UPDATE_DELETE_IMPLEMENTATION' is never read.

Method 'encodeRow' is never used.

The field 's3' is never read.

The local variable 'columns' is never read.
