What this PR does:
The default sync map based constraint cache for parquet is bad as it doesn't have TTL so memory usage can grow forever.
We set it as the default because there is another flag to control whether to enable the constraint cache. But that flag seems not working. So passing constraint cache function as nil instead to not use cache.
