This method (and dependencies) should probably move out of snuba/web/delete_query.py since we no longer want to support the synchronous delete from an endpoint (everything should flow through Kafka and the LW deletion consumer). But it can be follow-up work.

Bug: EAPItemsFormatter uses a hardcoded NUM_ATTRIBUTE_BUCKETS, causing incorrect bucket indexing if configuration changes, leading to silent delete failures.
Severity: CRITICAL | Confidence: 1.00
🔍 Detailed Analysis
The EAPItemsFormatter uses a hardcoded NUM_ATTRIBUTE_BUCKETS = 40 for calculating attribute bucket indices. If the num_attribute_buckets configuration changes (e.g., to 64), but the hardcoded value is not updated, delete queries will incorrectly calculate bucket indices. For example, an attribute hashing to 45 would target attributes_string_5 instead of attributes_string_45, leading to silent failures where data is not deleted as intended, causing data inconsistency.
💡 Suggested Fix
Parameterize EAPItemsFormatter to receive num_attribute_buckets as a constructor argument, injecting the value from the canonical storage configuration, similar to other transformers.

Potential issue: The `EAPItemsFormatter` uses a hardcoded `NUM_ATTRIBUTE_BUCKETS = 40`
for calculating attribute bucket indices. If the `num_attribute_buckets` configuration
changes (e.g., to 64), but the hardcoded value is not updated, delete queries will
incorrectly calculate bucket indices. For example, an attribute hashing to 45 would
target `attributes_string_5` instead of `attributes_string_45`, leading to silent
failures where data is not deleted as intended, causing data inconsistency.
