Review Comment:
There is no need of this if else if now. We can just directly update :
```
if (nextGlobalSnapInfo != null) {
nextGlobalSnapInfo.setGlobalPreviousSnapshotId(
snapInfo.getGlobalPreviousSnapshotId());
metadataManager.getSnapshotInfoTable().addCacheEntry(
new CacheKey<>(nextGlobalSnapInfo.getTableKey()),
CacheValue.get(trxnLogIndex, nextGlobalSnapInfo));
}
```
