+ - **Local Dictionary Configuration**
+
+ Local Dictionary is generated only for no-dictionary string/varchar
datatype columns. It helps in:
+ 1. Getting more compression on dimension columns with less cardinality.
+ 2. Filter queries and full scan queries on No-dictionary columns with
local dictionary will be faster as filter will be done on encoded data.
+ 3. Reducing the store size and memory footprint as only unique values
will be stored as part of local dictionary and corresponding data will be
stored as encoded data.
+
+ By default, Local Dictionary will be enabled and generated for all
no-dictionary string/varchar datatype columns.
