Apart from the configuration Homes shown in this segment, some Homes in other sections may also be related to ORC:

This flag must be established to real to restrict usage of indigenous vector map be a part of hash tables to the MultiKey in queries applying MapJoin.

This flag must be established to real to permit vectorizing making use of row deserialize. The default price is false.

Comma divided listing of configuration options which should not be read by normal consumer, for instance passwords.

This flag needs to be set to accurate to empower usage of indigenous speedy vector map sign up for hash tables in queries applying MapJoin.

This flag must be set to true to help vectorized manner of query execution. The default benefit is fake.

This flag needs to be established to real to allow vectorized manner with the reduce-aspect of question execution. The default price is accurate.

By default Tez will spawn containers of the scale of a mapper. This can be used to overwrite the default.

Adjustment to mapjoin hashtable size derived from desk and column statistics; the estimate of the quantity of keys is split by this worth. If the worth is why not try these out 0, statistics are certainly not utilised and hive.hashtable.initialCapacity is utilised alternatively.

Establish if we receive a skew crucial in be part of. If we see a lot more than the required quantity of rows with the same essential in sign up for operator, we think The real key site here as a skew be part of key.

This flag should be established to genuine to limit utilization of native vector map be part of hash tables for the MultiKey in queries employing MapJoin.
