 <td>Each CarbonData file has a companion CarbonIndex file which maintains the metadata about the data. These CarbonIndex files are read and loaded into driver and is used subsequently for pruning of data during queries. These CarbonIndex files are very small in size(few KB) and are many. Reading many small files from HDFS is not efficient and leads to slow IO performance. Hence these CarbonIndex files belonging to a segment can be combined into  a single file and read once there by increasing the IO throughput. This configuration enables to merge all the CarbonIndex files into a single MergeIndex file upon data loading completion.<strong>NOTE:</strong> Reading a single big file is more efficient in HDFS and IO throughput is very high. Due to this the time needed to load the index files into memory when query is received for the first time on that table is significantly reduced and there by significantly reduces the delay in serving the first query.</td>
