Re: [SQL] index row size 2728 exceeds btree maximum, 2713

Hi

It is not advisable to add a variable length data field in the Index key, since it is very difficult predict the size of the field which may vary from record to record.

are you included this field for Full text search on data field?

Hi,

One of the columns in primary key is of type "TEXT". I am able to insert with small data, but for around 3000 characters it's failing. How to handle that?

Thanks

Hi,

The issue looks like your Index width exceeds the maximum width of the index key limit, Please review the keys used in the index.

Column | Type

-----------+-----------------------+-----------

scan_id | bigint

host_ip | character varying(15)

port_num | integer

plugin_id | integer

severity | character varying(50)

Indexes:

"pk_scanned_port_info" PRIMARY KEY, btree (scan_id, host_ip, port_num, plugin_id, severity, data)

On inserting record I am getting this error "index row size 2728 exceeds btree maximum, 2713"
