GS_ABO_MODEL_STATISTIC

GS_ABO_MODEL_STATISTIC records the metadata, model name, and operator information of the ABO-based model estimation based on the feedback cardinality.

**Table 1** GS_ABO_MODEL_STATISTIC columns
Name	Data Type	Description
oid	oid	Hidden column.
modelname	name	Model name, which is unique.
createtime	timestamp	Time when a model is created or updated.
groupkey	oid	Hash of the operator corresponding to the model.
joinkey	oid	Hash of the operator connection shape corresponding to the model.
fixed_selectivity	real	Fixed selectivity for operators that do not contain numeric conditions.
avg_qerror	real	Average errors of qerror in the model.
max_qerror	real	Maximum errors of qerror in the model.
feedback_num	integer	Model training data volume.
status	integer	Model status. The value 0 indicates that the model is invalid. The value 1 indicates that the model is valid. The value 2 indicates that the model is to be updated. The value 3 indicates that the model is in the blocklist.
train_count	integer	Total number of model training times.
train_failure_count	integer	Number of model training failures.
prediction_count	integer	Total number of prediction times of a model.
predfiction_failure_count	integer	Number of model prediction failures.
rtable_ids	oid[]	Sequence of entering model conditions in the base table.
attnums	int2[]	Model condition input condition involves the column sequence.
