**NOTE**:
- * In case of data load failure to the SI table, then we make the SI table
disable by setting a hive serde
- property. The subsequent main table load will load the old failed loads along
with current load and
- makes the SI table enable and available for query.
+ * In case of data load failure to the SI table, segments of main table and SI
table will not be in sync.
+ In this scenario the subsequent query pruning will be performed at segment
level. It means all successful SI segments
+ will be pruned with SI table and rest of the segment pruning will be
performed with help of main table.
+ The subsequent main table load will load the old failed loads along with
current load and
+ makes the SI and main table segments in sync.
## Querying data
Direct query can be made on SI tables to check the data present in position
reference columns.
