 So you need to ensure preferentially load the Gluten jar to overwrite the jar of vanilla spark. Refer to [How to prioritize loading Gluten jars in Spark](https://github.com/oap-project/gluten/blob/main/docs/velox-backend-troubleshooting.md#incompatible-class-error-when-using-native-writer).
 
+
+### Runtime BloomFilter
+
+Velox BloomFilter's implementation is different from Spark's. So if `might_contain` falls back, but `bloom_filter_agg` is offloaded to velox, an exception will be thrown.
+
+#### example
+
+```sql
+SELECT might_contain(null, null) both_null,
+       might_contain(null, 1L) null_bf,
+       might_contain((SELECT bloom_filter_agg(cast(id as long)) from range(1, 10000)),
+            null) null_value
+```
+
+The below exception will be thrown.
+
+```
+Unexpected Bloom filter version number (512)
+java.io.IOException: Unexpected Bloom filter version number (512)
+ at org.apache.spark.util.sketch.BloomFilterImpl.readFrom0(BloomFilterImpl.java:256)
+ at org.apache.spark.util.sketch.BloomFilterImpl.readFrom(BloomFilterImpl.java:265)
+ at org.apache.spark.util.sketch.BloomFilter.readFrom(BloomFilter.java:178)
+```
+
+#### Solution
+
+Set the gluten config `spark.gluten.sql.native.bloomFilter=false` to fall back to vanilla bloom filter, you can also disable runtime filter by setting spark config `spark.sql.optimizer.runtime.bloomFilter.enabled=false`.
+
 ### Fallbacks
 Except the unsupported operators, functions, file formats, data sources listed in , there are some known cases also fall back to Vanilla Spark. 
 
@@ -24,9 +52,6 @@ Gluten only supports spark default case-insensitive mode. If case-sensitive mode
 In velox, lookaround (lookahead/lookbehind) pattern is not supported in RE2-based implementations for Spark functions,
 such as `rlike`, `regexp_extract`, etc.
 
-#### Runtime BloomFilter
-Velox BloomFilter's serialization format is different from Spark's. BloomFilter binary generated by Velox can't be deserialized by vanilla spark. So if `might_contain` falls back, we fall back `bloom_filter_agg` to vanilla spark also.
-
 #### FileSource format
 Currently, Gluten only fully supports parquet file format and partially support ORC. If other format is used, scan operator falls back to vanilla spark.
