Summary: - `get_entity` and `put_entity` command support in ldb - Input Format for `put_entity`: `ldb --db=<DB_PATH> put_entity <KEY> <COLUMN_1_NAME>:<COLUMN_1_VALUE> <COLUMN_2_NAME>:<COLUMN_2_VALUE> ...` - Output Format for `get_entity`: `<COLUMN_1_NAME>:<COLUMN_1_VALUE> <COLUMN_2_NAME>:<COLUMN_2_VALUE>` - If `get_entity` is called against non-wide column value (existing behavior), empty key (kDefaultWideColumnName) will be printed, appended by `:<COLUMN_VALUE>` - If `get` is called against wide column value (existing behavior), first column value is printed if the first column name is kDefaultWideColumnName. # Test Checks for `put_entity` and `get_entity` added in `ldb_test.py` ``` ❯ python3 tools/ldb_test.py took 45s at 10:45:44 AM Running testBlobBatchPut... .Running testBlobDump .Running testBlobPut... .Running testBlobStartingLevel... .Running testCheckConsistency... .Running testColumnFamilies... .Running testCountDelimDump... .Running testCountDelimIDump... .Running testDumpLiveFiles... .Running testDumpLoad...
