摘要:
A method, system and computer program product for improving performance of concurrent data inserting provide the features of adding a prefix to each key value in an index, wherein the prefix has a default value, allocating a corresponding prefix to each concurrent inserting process in response to an occurrence of a hot spot mode being detected, wherein each allocated prefix is different from the default value, performing an inserting operation in the hot spot mode, wherein the inserting operation includes deciding whether a key value can be inserted with the default value of the prefix, in response to a determination that an insertion of a key value with the default value of the prefix can be performed, inserting the key value with the default value of the prefix, and in response to a determination that an insertion of a key value with the default value of the prefix cannot be performed, inserting the key value with another prefix allocated by the inserting process.
