[TRAFODION-3145] Make "hbase_options" as default setting and use cqd …
…to change the default setting
As we know, for performance thinking, we always need to add below syntax in
“create table” syntax. And I know in latest version, we have made “ATTRIBUTES
ALIGNED FORMAT” as default, do we have a plan that make HBASE_OPTIONS(including
ENCODING、COMPRESSION、MEMESTORE) as the default setting when creating table? I
think this will be easier for end users?
ATTRIBUTES ALIGNED FORMAT
HBASE_OPTIONS
(
DATA_BLOCK_ENCODING = 'FAST_DIFF',
COMPRESSION = 'SNAPPY',
MEMSTORE_FLUSH_SIZE = '1073741824'
)
;
Trafodion has
cqd HBASE_DATA_BLOCK_ENCODING_OPTION ‘FAST_DIFF’;
cqd HBASE_COMPRESSION_OPTION ‘SNAPPY’;
Add
cqd HBASE_MEMSTORE_FLUSH_SIZE_OPTION '1073741824' ;
So one can use these values without explicitly specify them when create
table.
