/insert/records

URL: https://<aws.fqdn>/<aws.cluster.name>/gpudb-0/insert/records

Adds multiple records to the specified table. The operation is synchronous, meaning that a response will not be returned until all the records are fully inserted and available. The response payload provides the counts of the number of records actually inserted and/or updated, and can provide the unique identifier of each added record.

The input parameter options parameter can be used to customize this function's behavior.

The update_on_existing_pk option specifies the record collision policy for inserting into a table with a primary key, but is ignored if no primary key exists.

The return_record_ids option indicates that the database should return the unique identifiers of inserted records.

Input Parameter Description

Name

Type

Description

table_name

string

Name of table to which the records are to be added, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.

list

array of bytes

An array of binary-encoded data for the records to be added. All records must be of the same type as that of the table. Empty array if input parameter list_encoding is json.

list_str

array of strings

An array of JSON encoded data for the records to be added. All records must be of the same type as that of the table. Empty array if input parameter list_encoding is binary.

list_encoding

string

The encoding of the records to be inserted. The default value is binary. The supported values are:

binary
json

options

map of string to strings

Optional parameters. The default value is an empty map ( {} ).

Supported Parameters (keys)

Parameter Description

update_on_existing_pk

Specifies the record collision policy for inserting into a table with a primary key. If set to true, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record (the new data will be "upserted"). If set to false, any existing table record with primary key values that match those of a record being inserted will remain unchanged, while the new record will be rejected and the error handled as determined by ignore_existing_pk, allow_partial_batch, & return_individual_errors. If the specified table does not have a primary key, then this option has no effect. The default value is false.

Supported Values	Description
true	Upsert new records when primary keys match existing records
false	Reject new records when primary keys match existing records

ignore_existing_pk

Specifies the record collision error-suppression policy for inserting into a table with a primary key, only used when not in upsert mode (upsert mode is disabled when update_on_existing_pk is false). If set to true, any record being inserted that is rejected for having primary key values that match those of an existing table record will be ignored with no error generated. If false, the rejection of any record for having primary key values matching an existing record will result in an error being reported, as determined by allow_partial_batch & return_individual_errors. If the specified table does not have a primary key or if upsert mode is in effect (update_on_existing_pk is true), then this option has no effect. The default value is false.

Supported Values	Description
true	Ignore new records whose primary key values collide with those of existing records
false	Treat as errors any new records whose primary key values collide with those of existing records

return_record_ids

If true then return the internal record id along for each inserted record. The default value is false. The supported values are:

true
false

truncate_strings

If set to true, any strings which are too long for their target charN string columns will be truncated to fit. The default value is false. The supported values are:

true
false

return_individual_errors

If set to true, success will always be returned, and any errors found will be included in the info map. The "bad_record_indices" entry is a comma-separated list of bad records (0-based). And if so, there will also be an "error_N" entry for each record with an error, where N is the index (0-based). The default value is false. The supported values are:

true
false

allow_partial_batch

If set to true, all correct records will be inserted and incorrect records will be rejected and reported. Otherwise, the entire batch will be rejected if any records are incorrect. The default value is false. The supported values are:

true
false

dry_run

If set to true, no data will be saved and any errors will be returned. The default value is false. The supported values are:

true
false

Possible Parameters (keys)	Parameter Description
