Type:

R/W:
R/W
Default:
EMPTY
IBProvider:

This property configures a connection data compression between provider’s own client and database’s server. It’s allowed an empty value or one value from the following list:
| Value | Description |
| disabled | Compression disabled. |
| enabled | Compression enabled. |
| required | Connection data must be compressed. |
By default the provider does not prohibit connection data compression, if database’s server suggests doing it.
Data compression is supported by Firebird since the third version (13th protocol).
Before specifying «remote:wire_compression=enabled» or «remote:wire_compression=required», check presence of zlib1.dll in the directory with the FB3 binary files. If the server does not has this DLL, the provider will return a read error from the connection port.
