| Description | The allocation ratio of StorageEngine, QueryEngine, SchemaEngine, Consensus, StreamingEngine, and Free Memory. Since V2.0.11, half of the free memory serves as the total memory budget of the AutoResizingBuffer in the RPC layer, which limits the overall memory usage of framed transport read/write buffers and compression/decompression buffers. |

### 1.1 Float Precision

The time series of **FLOAT** and **DOUBLE** type can specify (MAX\_POINT\_NUMBER, see [this page](../SQL-Manual/SQL-Manual_apache) for more information on how to specify), which is the number of digits after the decimal point of the floating point number, if the encoding method is [RLE](../Technical-Insider/Encoding-and-Compression.md) or [TS\_2DIFF](../Technical-Insider/Encoding-and-Compression.md). If MAX\_POINT\_NUMBER is not specified, the system will use [float\_precision](../Reference/DataNode-Config-Manual.md) in the configuration file `iotdb-system.properties`.
