Yes, you are right. I add log to record the time of seek and find that
sometimes it is very slow. Then I use the rocksdb's files to test locally
and the same problem appears. It is very weird to find that rocksdb's seek
iterate data one by one. Until now, I add cache for rocksdb. The time is
faster than before but not solved completely. Added code is below:
public ColumnFamilyOptions createColumnOptions() {
// return new ColumnFamilyOptions();
BlockBasedTableConfig blockBasedTableConfig = new
BlockBasedTableConfig();
blockBasedTableConfig.setBlockCacheSize(1024 * 1024 *
1024);
ColumnFamilyOptions columnFamilyOptions = new
ColumnFamilyOptions();
columnFamilyOptions.setTableFormatConfig(blockBasedTableConfig);
return columnFamilyOptions;
}
