blog talks about different indices and when to use which one.
+
+Hoodie dataset can be of two types in general, partitioned and
non-partitioned. So, most index has two implementations one for partitioned
dataset and another for non-partitioned called as global index.

+- InMemory
+- Bloom
+- Simple
+- Hbase
+
+You could use “hoodie.index.type” to choose any of these indices.
+
+### 1.1 Motivation
+Different workloads have different access patterns. Hudi supports different
indexing schemes to cater to the needs of different workloads. So depending on
one’s use-case, indexing schema can be chosen.
