A data storage method includes the following steps: storing data to be stored into a mutable table, the mutable table being located in a RAM. If a storage content of the mutable table is greater than or equal to a preset storage content threshold, modifying the mutable table into an immutable table and stopping receiving storage of the data to be stored; if a storage content of a lowest level in a disk is greater than or equal to a storage content threshold of a present level, and next level higher in the disk is stored with columnar format, storing data of the lowest level to the next level in the columnar format; and if the lowest level is stored with row format, storing data in the immutable table to the lowest level in the row format.

Data storage method and data storage engine

Systems and methods for switching a data access synchronization strategy for a data structure are provided. Workload characteristics of one or more threads of execution access the data structure are monitored. A target data access synchronization strategy is determined. If the current strategy is different than the target strategy, the current strategy is switched to the target data access synchronization strategy for the data structure.
