# Proposed changes Issue Number: close #xxx This pr mainly brings one ## Problem summary This PR implements a buffered reader optimized for object reading, which can pre-read in segments based on the buffer size required by the user(which is 16MB by default, and can be specified by user). In multiple local tests, Doris without this optimization took an average of 23 minutes to load and import the table `lineitem` of TPCH SF100 data of 79G using S3 load. With this optimization, the average time was reduced to around 5 minutes and 30 seconds.
