ant_nebula updated SPARK-24727:
-------------------------------
Description:
private val cache = CacheBuilder.newBuilder().maximumSize(100).build
The cache 100 in
org.apache.spark.sql.catalyst.expressions.codegen.CodeGenerator is too small
for realtime streaming calculation, although is ok for offline calculation.
Because realtime streaming calculation is mostly more complex is one driver,
and performance sensitive.
I suggest spark support configging for user with default 100, such as
spark.codegen.cache.
