Resources:1.-fpicGenerate position-independent Code (PIC) suitable for use with a shared library, if supported for the target machine. Such code accesses all constant addresses through a global offset table (GOT). The dynamic loader resolves the GOT entries when the program starts (the dynamic loader are not part of GCC; it's part of The operating system). If the GOT size for the linked executable exceeds a machine-specific maximum size, you get an er

The regular expression library re is a very important library.First, the regular expression has two types of representations, one is the raw string type (the primitive type), that is, we often see the wording of R ", and the other is not with R, called the string type. The purpose of raw string is to use the escaped character as a normal character, so in general, we are using the raw string type, which is more convenient.The following is the main way

NET core already does not support RealProxy, it can only be started anew. By flipping through the code of. NET core, we finally found an assembly: System.Reflection.DispatchProxy. In this program, there is a type dispatchproxy. (inspiration still comes from WCF.) WCF is a heavyweight API in. NET, and Microsoft cannot support

various column mapping schemes:Parquet Thrift also has a lot of space to optimize, and parquet is faster before the number of columns selected is less than 13 columns, which is relatively flat and most columns are generated. You can also use the predicate push-down policy so that parquet can skip some data records that do not meet the filter criteria. Parquet stores some statistics, such as the chunks of records, so in some scenarios, you can skip the entire block of data (chunk) b

performance is related to the number of columns in the data, and Null reads are not time consuming. Skip the fields that you don't need, as follows: Although, there is no reduction in I/O overhead However, you can encode only the fields of interest into the object The CPU time spent decoding a string is much higher than the overhead of reading from disk + skipping encoded bytes! Look at the comparison of the various column mapping schemes:Parquet Thrift also has a lot
