MySQL Error 4144: Bulk Parser Buffer Exceeded
Description
This error occurs when MySQL attempts to parse a data file (e.g., during `LOAD DATA INFILE`), and the total number of columns that need to be buffered for processing exceeds an internal server-defined maximum. It indicates that the input data's structure or size is too complex for the current buffer settings.
Error Message
The number of input columns that need to be buffered for parsing exceeded predefined buffer max size for file '%s'.
Known Causes
4 known causesExcessive Number of Columns
The input data file contains an unusually high number of columns, exceeding MySQL's internal limits for buffering during parsing.
Very Wide Columns or Large Data Size
Even with a moderate column count, individual columns containing very large data types or extensive content can collectively exhaust the parsing buffer.
Low Server Buffer Configuration
The MySQL server's internal buffer limits for bulk parsing operations are set too low for the size or complexity of the data being processed.
Malformed or Corrupted Input File
An incorrectly formatted or corrupted input file might lead MySQL to misinterpret column boundaries, causing it to buffer an unexpectedly large number of 'columns'.
