default_transport_compress_func

Note

• Due to the architecture optimization of OceanBase Database V4.x, each module selects its own compression algorithm instead of using the unified default compression algorithm, and this parameter has been deprecated since OceanBase Database V4.0.0.
• For OceanBase Database V4.x:
• In OceanBase Database V4.1.0 and later, you can use the tenant-level parameter log_transport_compress_func to specify the algorithm for compressing logs for transmission. For more information about the log_transport_compress_func parameter, see log_transport_compress_func.
• In OceanBase Database V4.2.1 and later versions of V4.2.x, you can use the tenant-level parameter kv_transport_compress_func to specify the algorithm for compressing OBKV-Table query results for transmission. In OceanBase Database V4.3.x, you can use the cluster-level parameter tableapi_transport_compress_func to specify the algorithm for compressing OBKV-Table query results for transmission. For more information about the tableapi_transport_compress_func parameter, see tableapi_transport_compress_func.

Description

default_transport_compress_func specifies the remote procedure call (RPC) compression algorithm for the entire cluster.

Attributes

Attribute	Description
Type	String
Default value	none
Value range	none lz4_1.0 snappy_1.0 zlib_1.0 zstd_1.0 zstd_1.3.8
Modifiable	Yes. You can use the ALTER SYSTEM SET statement to modify the parameter.
