In documentation said:
This limits the maximum size of data record in binary form. The binary form is the form used by Clover when manipulating data. Parser are here to convert text representation or database representation of data records to Clover’s internal. Some data can have larger representation in text form - dates, numbers and some shorter - strings, for example (java stores strings in unicode - 16bits per character) If you start getting buffer overflow or similar errors, increase this value. The limit is theoretically 2^31 , but you should keep it under 64K. Clover at runtime allocates several internal buffers of “MAX_RECORD_SIZE”, thus increasing this value increases also memory utilization.
I require to transmit records, that have size 1 Mb and larger. If I set MAX_RECORD_SIZE = 10 000 000, the lack of memory exception appear.
