COMMANDS
DDL
CREATE INDEX <index> ON <ns>[.<set>] (<bin>) NUMERIC|STRING
CREATE LIST/MAPKEYS/MAVALUES INDEX <index> ON <ns>[.<set>] (<bin>) NUMERIC|STRING
DROP INDEX <ns>[.<set>] <index>
REPAIR INDEX <index> ON <ns>[.<set>]
<ns> is the namespace for the index.
<set> is the set name for the index.
<index> is the name of the index.
Examples:
CREATE INDEX idx_foo ON test.demo (foo) NUMERIC
DROP INDEX test.demo idx_foo
REPAIR INDEX idx_foo ON test.demo
DML
INSERT INTO <ns>[.<set>] (PK, <bins>) VALUES (<key>, <values>)
DELETE FROM <ns>[.<set>] WHERE PK = <key>
<ns> is the namespace for the record.
<set> is the set name for the record.
<key> is the record's primary key.
<key> is the record's primary key.
<bins> is a comma-separated list of bin names.
<values> is comma-separated list of bin values. Keep it NULL (case insensitive & w/o quotes) to delete the bin
Examples:
INSERT INTO test.demo (PK, foo, bar) VALUES ('key1', 123, 'abc')
DELETE FROM test.demo WHERE PK = 'key1'
QUERY
SELECT <bins> FROM <ns>[.<set>]
SELECT <bins> FROM <ns>[.<set>] WHERE <bin> = <value>
SELECT <bins> FROM <ns>[.<set>] WHERE <bin> BETWEEN <lower> AND <upper>
SELECT <bins> FROM <ns>[.<set>] WHERE PK = <key>
SELECT <bins> FROM <ns>[.<set>] IN <indextype> WHERE <bin> = <value>
SELECT <bins> FROM <ns>[.<set>] IN <indextype> WHERE <bin> BETWEEN <lower> AND <upper>
<ns> is the namespace for the records to be queried.
<set> is the set name for the record to be queried.
<key> is the record's primary key.
<bin> is the name of a bin.
<value> is the value of a bin.
<indextype> is the type of a index user wants to query. (LIST/MAPKEYS/MAPVALUES)
<bins> can be either a wildcard (*) or a comma-separated list of bin names.
<lower> is the lower bound for a numeric range query.
<upper> is the lower bound for a numeric range query.
Examples:
SELECT * FROM test.demo
SELECT * FROM test.demo WHERE PK = 'key1'
SELECT foo, bar FROM test.demo WHERE PK = 'key1'
SELECT foo, bar FROM test.demo WHERE foo = 123
SELECT foo, bar FROM test.demo WHERE foo BETWEEN 0 AND 999
MANAGE UDFS
REGISTER MODULE '<filepath>'
SHOW MODULES
REMOVE MODULE <filename>
DESC MODULE <filename>
<filepath> is file path to the UDF module(in single quotes).
<filename> is file name of the UDF module.
Examples:
REGISTER MODULE '~/test.lua'
SHOW MODULES
DESC MODULE test.lua
REMOVE MODULE test.lua
INVOKING UDFS
EXECUTE <module>.<function>(<args>) ON <ns>[.<set>]
EXECUTE <module>.<function>(<args>) ON <ns>[.<set>] WHERE PK = <key>
AGGREGATE <module>.<function>(<args>) ON <ns>[.<set>] WHERE <bin> = <value>
AGGREGATE <module>.<function>(<args>) ON <ns>[.<set>] WHERE <bin> BETWEEN <lower> AND <upper>
<module> is UDF module containing the function to invoke.
<function> is UDF to invoke.
<args> is a comma-separated list of argument values for the UDF.
<ns> is the namespace for the records to be queried.
<set> is the set name for the record to be queried.
<key> is the record's primary key.
<bin> is the name of a bin.
<value> is the value of a bin.
<lower> is the lower bound for a numeric range query.
<upper> is the lower bound for a numeric range query.
Examples:
EXECUTE myudfs.udf1(2) ON test.demo
EXECUTE myudfs.udf1(2) ON test.demo WHERE PK = 'key1'
AGGREGATE myudfs.udf2(2) ON test.demo WHERE foo = 123
AGGREGATE myudfs.udf2(2) ON test.demo WHERE foo BETWEEN 0 AND 999
