Rajeshbabu Chintaguntla reassigned PHOENIX-7123: ------------------------------------------------ Assignee: Nihal Jain > Support for multi-column split keys > ----------------------------------- > > Key: PHOENIX-7123 > URL: https://issues.apache.org/jira/browse/PHOENIX-7123 > Project: Phoenix > Issue Type: New Feature > Components: phoenix > Reporter: Rajeshbabu Chintaguntla > Assignee: Nihal Jain > Priority: Major > > Currently there is only way to create split keys by passing array of strings > which will be leading parts of rowkey. If a table have multi-column row key > or non varchar key application developers need to do lot of research to > prepare the split keys according to columns types and need to dig internal > details of how the row key formed with separators in case of variable length > columns etc. We can support the multi column split keys by passing array of > arrays of identifiers so that split keys formed by considering data types, > fixed length or variable length column types etc. > Even we can support splitting existing regions with alter kind of queries so > that need not relay on hbase APIs to split the regions. > Example syntax: > {code:sql} > create table test(a integer not null, b varchar not null, c float, d bigint, > constraint pk primary key(a,b)) split on ([1, 'bob'],[5, 'fan'],[7,'nob']) > {code} > Similarly for dynamic splitting existing regions we can define alter command > also as below > {code:sql} > alter table test split on ([3, 'cob'],[4, 'end']) > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
