------------------------------------
Hi, [~jark] nice suggestion!
{quote}(I think "{}" is not allowed in es index name, right?)
{quote}
"{}" is allowed in es index name from my test in es 6, but I think it’s ok
because using "{}" in index name is unusual and meaningless.
{quote}We can have another property 'connector.index-alias' to declare the
alias, because if the index is not a dynamic index, it should also can have an
alias.
{quote}
In this way, we can support alias event if index is not a dynamic index.
So, the final design will like following:
{code:java}
CREATE TABLE es_sink_table (
log_source varchar ,
log_content varchar ,
log_level bigint ,
log_ts timestamp,
) WITH (
'connector.type' = 'elasticsearch',
'connector.version' = '6',
'connector.index'='my-log-{log_ts|yyyy-MM-dd}'，
# elasticsearch index name, Flink support create index based on field at
# runtime dynamically, the index value comes from the dynamicIndex
# pattern when the field type is varchar, eg:'my-log-{log_source}',the #
dynamicIndex pattern support format and parse date by Java
# SimpleDataFormat when the field type is timestamp/date/bigint,
# eg:'my-log-{log_ts|yyyy-MM-dd}'.
'connector.index-alias'='my-log'，
# index alias name, the alias name mapping to all indies that
# creatd from 'connector.dynamicIndex'.
…)
{code}

> Becuase the es 6/7 not support ttl. so User need clean the index by
> timestamp. Add dynamic index is a useful function. Add with properties
> 'dynamicIndex' as a switch for open dynamicIndex. Add with properties

> change cycle mode.

> ||With property||discribe||default||Required||
