A key-value store.

First, make sure you have Go installed and $GOROOT set properly. You will need Go1 or a weekly release to build; Go r60.3 or earlier is too old.

$ git clone git://github.com/codeslinger/latenza.git

• CREATE table name
  • Create table using the field name as the table's primary key.
• DROP table
  • Delete table and all of its contents.
• GET table key [field]*
  • Retrieves the fields specified within record key. If no field is specified, gets all attributes of record.
• MGET table key [key]*
  • Retrieves multiple full records in one call.
• SET table key field value [field value]*
  • Sets field=value for all specified field/value pairs for the record specified by key
• DEL table key [field]*
  • Delete all specified fields from the record specified by key. If no fields are specified, deletes the entire record.
• INCR table key field delta [field delta]*
  • Increment the value of field in the record key by the amount delta.
• ADD table key field value [field value]*
  • Insert value(s) into set field within record key.
• SUB table key field value [value]*
  • Delete the values in field within record key.
• CARD table key field
  • Returns the cardinality of the set specifed by field in the record specified by key.
• MEMBER table key field value
  • Returns whether or not value is a member of set field within record key.
• STATS
  • Returns status report for running instance.

  • String (UTF-8 encoded)
  • Integral (64-bit signed integer)
  • Set of strings
  • Set of integers
• Data types are specified at the time of field creation.
• Attempts to call INCR on a string value will result in an error response.

• Table, key and field names are interpreted as UTF-8 byte strings. They must be 1-256 bytes in length.
• Total size of a given record must be less than or equal to 1MB over all field values.
