BiteTheDDDDt opened a new pull request, #43360:
URL: https://github.com/apache/doris/pull/43360
…alized_bytes
### What problem does this PR solve?
add LZ4_MAX_INPUT_SIZE check on
DataTypeString::get_uncompressed_serialized_bytes
Problem Summary:
/*! LZ4_compressBound() :
Provides the maximum size that LZ4 compression may output in a "worst
case" scenario (input data not compressible)
This function is primarily useful for memory allocation purposes
(destination buffer size).
Macro LZ4_COMPRESSBOUND() is also provided for compilation-time
evaluation (stack memory allocation for example).
Note that LZ4_compress_default() compresses faster when dstCapacity is
>= LZ4_compressBound(srcSize)
inputSize : max supported value is LZ4_MAX_INPUT_SIZE
return : maximum output size in a "worst case" scenario
or 0, if input size is incorrect (too large or negative)
